The Reunion M5 series Industrial waterproof connector is a purpose-built miniature circular interconnect, certified to DIN EN 61076-2-105, specifically designed for sensors, actuators, and control modules where space constraints rule out M8 or M12 formats. Unlike standard miniature connectors that rely solely on material declarations, this M5 series Industrial waterproof connector integrates a threaded locking mechanism with a precision-compressed O-ring sealing system, delivering verified IP67 protection (1m immersion for 30 minutes, batch-tested with water — not theoretical calculations). The nickel-plated metal shell provides mechanical robustness and effective EMI shielding, while the precision-machined brass contacts — ensure stable signal transmission. Available in 2-, 3-, and 4-pin configurations, the M5 series Industrial waterproof connector supports discrete sensor signals, analog outputs (0-10V, 4-20mA), and low-power distribution up to 1A/60V.

All production processes for the M5 series Industrial waterproof connector operate under statistical process control (SPC). Batch IP67 immersion testing is performed in clear water at 1m depth for 30 minutes, with the connector fully mated. Test records — including photographs and electrical post-test data — are archived and available for customer audit within 24 hours of request.
Reunion recommends 0.2–0.3Nm for the panel-mount fixing nut — hand-tight plus a quarter-turn with a torque wrench. Over-tightening beyond 0.4Nm can stress the O-ring and degrade sealing performance. For critical washdown applications, we recommend factory-overmolded cable assemblies to eliminate field-installation errors entirely. O-rings should be inspected quarterly and replaced after 50–100 mating cycles for applications with daily washdown.
Independent lab comparisons (ITEP, 2025) confirm that the Reunion M5 series Industrial waterproof connector matches the electrical durability (contact resistance <3mΩ after 500 cycles) and IP67 sealing integrity of premium European equivalents. The primary differences are: (1) Reunion's ≥0.3µm gold plating equals or exceeds their standard spec; (2) PUR cables are a standard, in-stock option versus a special-order item; (3) 12-15 day lead time versus 4-8 weeks. For procurement, this translates to a 22% TCO reduction without sacrificing reliability.
Absolutely. Samples are available within 5–7 days. We encourage customers to perform their own washdown simulation — and we offer engineering support to review your test setup and application requirements.
