A B Series Metal Push-pull Connector combines a metal circular housing with a push-pull locking mechanism to support fast, secure electrical connections. Depending on the selected configuration, this connector family can accommodate multiple contact arrangements, different mounting styles, and solder, crimp, or PCB termination options. These characteristics make it worth considering for equipment that requires repeated connection, space-efficient installation, and reliable signal or power transmission. This article explains how the connector works, its main design advantages, application scenarios, selection criteria, and quality considerations. It also outlines the technical information buyers should confirm with Reunion before specifying a connector for a new design or replacement project.
A B Series Metal Push-pull Connector is a circular electrical connector that uses a push-pull self-latching mechanism to connect and disconnect mating components. Unlike conventional threaded connectors, which typically require rotational tightening, a push-pull design allows users to establish a connection by inserting the plug into its compatible receptacle. The locking mechanism engages when the connector is correctly mated and releases through the designated pull action.
The metal housing provides a robust mechanical interface and may contribute to electromagnetic compatibility when the connector's shielding structure is correctly integrated into the equipment. Depending on the configuration, the connector can support electrical signal transmission, power delivery, or a combination of circuit requirements.
Reunion's B Series product information covers multiple connector sizes and configurations. Available options may include straight or angled constructions, different contact arrangements, and alternative termination methods. Buyers should consult the applicable product drawing and specification to verify the exact features of a selected model.

The push-pull mechanism is designed to make electrical connection operations straightforward without sacrificing the security of the mating interface. Its operation can be understood in three stages.
This operating principle is particularly useful in equipment that requires frequent connection changes, maintenance access, or operation in confined spaces. It can reduce the time spent on repetitive connector handling compared with connection systems that require multiple tightening steps.
However, the locking mechanism should not be treated as a substitute for correct installation. Cable strain, connector misalignment, incompatible mating parts, and improper handling can still compromise connection performance. Users should follow the manufacturer's instructions for mating, release, and cable management.
The self-latching design supports quick mating and intentional release. It is useful when operators need to connect or disconnect electrical circuits regularly without repeatedly turning a coupling nut.
The metal shell provides a durable connector structure and can support shielding continuity in appropriately designed systems. Effective electromagnetic interference protection depends on the complete connection, including shell contact, cable shielding, grounding, and installation quality.
Different equipment designs require different numbers of electrical circuits. The B Series family includes multiple contact configurations, allowing engineers to assess options according to signal count, power requirements, available space, and wiring architecture. The exact number of contacts and their electrical ratings must be verified for the selected model.
Depending on the product configuration, termination choices may include:
Contact style, conductor size, assembly tooling, and installation space should be evaluated together before the connector is specified.
Keying features help guide the plug into the correct mating orientation. This can reduce the risk of incorrect alignment and improve assembly consistency, especially when equipment contains multiple similar connectors.
The B Series Metal Push-pull Connector can be considered for equipment that benefits from a compact circular interface and convenient connection handling. Actual suitability depends on the selected model's electrical, mechanical, and environmental ratings.
For medical, safety-critical, or other regulated applications, the connector must meet the requirements of the complete equipment design. A connector's general product description does not independently establish compliance with every application-specific standard.
Choosing a connector based only on appearance or shell size can lead to compatibility problems. Engineers and purchasing teams should evaluate the full electrical and mechanical requirements before placing an order.
Identify how many power and signal circuits the equipment needs. Allow for the intended wiring architecture and confirm whether the selected insert supports the required contact arrangement. Do not assume that connectors with similar external dimensions have identical internal layouts.
Check the rated current and working voltage for the exact connector configuration. These values can vary with contact diameter, contact count, conductor size, temperature, and operating conditions. The maximum rating of one model should never be applied automatically to the entire series.
Choose solder, crimp, or PCB termination according to the equipment design and manufacturing process. Confirm the required tooling, cable specification, PCB layout, and available assembly space.
Verify the plug and receptacle part numbers, shell dimensions, panel cutout, mounting arrangement, and cable diameter range. For replacement projects, compare the existing connector's drawings and contact arrangement rather than relying on the product name alone.
Review operating temperature, humidity, vibration, mechanical shock, corrosion exposure, and ingress protection. Select a protection level appropriate to the intended environment and ensure that the complete assembled connection meets the requirement.
The following table summarizes the main factors to consider when evaluating a B Series connector for a new equipment design.
| Selection Factor | What to Check | Why It Matters |
|---|---|---|
| Contact count | Number and arrangement of electrical contacts | Ensures the connector supports the required circuits |
| Electrical ratings | Rated current, working voltage, and contact specifications | Helps prevent electrical overstress and unsuitable operating conditions |
| Termination type | Solder, crimp, or PCB configuration | Determines wiring method, tooling, and assembly requirements |
| Connector orientation | Straight or angled construction, where available | Helps accommodate cable routing and installation space |
| Locking and alignment | Compatible mating parts and keying arrangement | Reduces incorrect mating and unintended disconnection risks |
| Environmental protection | IP rating, temperature, humidity, vibration, and corrosion conditions | Supports reliable operation in the intended environment |
| Service requirements | Expected mating frequency and maintenance access | Helps determine whether the connector suits the operating workflow |
This table is a selection checklist, not a substitute for the official product datasheet. Confirm every critical value against the current technical documentation for the exact part number.
Correct installation helps preserve connector performance throughout the equipment's service life. Even a well-designed connector can fail prematurely if it is assembled incorrectly or exposed to conditions outside its rated limits.
Cleaning methods and lubricants, if any are permitted, should follow the manufacturer's instructions. Unapproved chemicals or abrasive tools may damage contact plating, insulation, or sealing components.
For OEM projects and repeated production orders, connector quality should be assessed through documented requirements rather than general claims alone. A structured evaluation can help purchasing teams compare suppliers and reduce integration risks.
Before approving a connector, consider the following points:
Reunion's B Series product page provides a starting point for product evaluation. For critical design decisions, buyers should obtain the current model-specific specifications and confirm that the proposed configuration meets their requirements.
Its main advantage is the combination of push-pull self-locking operation and a metal circular connector structure. This design can simplify repeated mating and disconnection while supporting secure connections in compatible equipment.
Depending on the selected model, options may include solder, crimp, and PCB contacts. Buyers should confirm the available termination style and assembly requirements for the exact part number.
It may be suitable for compatible medical and diagnostic equipment when its electrical, mechanical, cleaning, and environmental requirements match the application. The complete device manufacturer must verify all relevant regulatory and safety requirements before use.
No. Environmental protection varies by connector design and configuration. Buyers should check the stated IP rating and whether it applies to the mated assembly, unmated connector, or another specified condition. Do not assume that a metal housing alone provides waterproof protection.
Provide the required contact count, electrical ratings, plug and receptacle types, termination method, cable dimensions, mounting requirements, operating environment, and estimated order quantity. An existing part number, drawing, or sample can also help the supplier assess compatibility.
A B Series Metal Push-pull Connector can be a practical choice for equipment requiring convenient connection handling, secure self-latching, and a compact circular electrical interface. The right configuration depends on contact count, current and voltage ratings, termination method, mechanical compatibility, and environmental requirements. By checking the detailed specifications and validating the connector within the intended equipment, engineers and purchasing teams can make more confident sourcing decisions.
