Shenzhen REUNION Electronic Co., Ltd. has been supplying interconnect solutions for industrial automation since 2011. The company’s product range covers circular connectors and cable assemblies used in robotic cells, sensor networks, motor drives, and control cabinets. Industrial automation connectors from REUNION are engineered to maintain stable power, signal, and data transmission under continuous vibration, temperature fluctuation, dust, and oil exposure.
Rather than offering general-purpose components, the engineering team works from application parameters such as mating cycles, current load, cable routing, and environmental sealing to specify or develop a suitable connector series. This approach supports both standard installations and custom machine builds.
Connectors in automation equipment face mechanical stress beyond simple electrical contact. Actuators, indexing tables, and moving gantries generate vibration that can loosen threaded or bayonet couplings over time. Dust from machining operations and coolant splashes can degrade contact surfaces. For these reasons, many machine builders specify interfaces with positive locking and sealed construction. Waterproof Connector designs rated IP67 or higher are common on machine exteriors and washdown zones, while lighter-duty non-sealed versions remain appropriate inside protected electrical enclosures.
Shell material also affects service life. Nickel-plated brass or stainless steel resists impact and provides shielding in noisy electrical environments. Engineering plastics such as PBT or PA offer adequate rigidity at lower weight and cost, particularly for sensor-level connections.
Field-level automation frequently combines low-current sensor signals with higher-current actuator power on separate or shared conductors. Compact circular formats such as M12 Series Connector and M8 variants have become standard for Ethernet, I/O link, and sensor connections due to their coding options and reliable field termination. When a single connection point must carry both motor power and feedback signals, Power and Signal Connector configurations allow hybrid contact layouts inside one housing, reducing harness complexity and installation time.
REUNION supplies these interfaces with solder, crimp, or PCB terminations. Custom pin assignments are supported to match specific PLC modules, servo drives, or sensor types, and the engineering team verifies current-carrying capacity and dielectric strength before finalizing a layout.
The Shenzhen factory occupies approximately 4,000 square meters and employs about 150 people across 10 production lines. Monthly output capacity is around 100,000 sets. More than 30 customized automation projects are completed each year, including angled connectors, overmolded cable exits, and application-specific keying or color coding. The company holds 13 patents and 2 software copyrights related to connector design and assembly processes.
Quality systems follow ISO 9001 and ISO 14001, with ISO 13485 certification covering medical-related products. Incoming materials are controlled through an approved supplier list, and each batch is tracked in the ERP system from raw material receipt to final continuity, insulation resistance, and dimensional checks.
Metal housings are recommended when the connection point is exposed to impact, frequent coupling, or electromagnetic interference. Plastic housings work well in lighter-duty locations, offer corrosion resistance, and help reduce system weight. The decision should consider mounting position, cable strain, and whether shielding continuity is required.
Yes. In-house processes include wire cutting, stripping, soldering, and overmolding. Customers specify wire gauge, jacket material, cable length, and termination type. REUNION then supplies assemblies ready for direct integration into machines or control panels, reducing on-site wiring errors.
Depending on the series and sealing configuration, products range from IP50 for protected cabinet use up to IP68 for temporary immersion and high-pressure washdown. Sealed versions incorporate O-rings, gaskets, and cable glands. The correct rating depends on whether the connector is located inside an enclosure, on a machine frame, or exposed to direct liquid spray.
