Space constraints on your production line? When sourcing a compact yet industrial-grade interconnect, Reunion M5 series industrial connector delivers the ruggedness of M12 in a 5mm footprint. Engineered for robot arms and dense sensor arrays, this threaded circular solution solves assembly headaches with IP67 sealing and gold-plated contacts. Procure a miniature workhorse that maintains signal integrity where space is the ultimate luxury—Reunion M5 series industrial connector ensures your automation upgrade pays off without retrofit nightmares.
The Reunion M5 series industrial connector was born on the factory floor, not just in a CAD library. We watched engineers struggle with oversized M8 plugs on compact pick-and-place heads — so we designed this DIN EN 61076‑2‑105 compliant miniature circular connector to fit where others simply cannot. With a 5mm coupling thread, it reduces sensor pitch to just 15mm, enabling cabinet space savings of up to 30%. Available in 2-, 3-, and 4-pin configurations, it handles sensor signals, 4-20mA analog loops, and low-power distribution. The threaded locking mechanism has been field-verified on 200+ robotic installations — it resists loosening under continuous 50Hz vibration. Entirely manufactured in Reunion's Shenzhen cell, every batch undergoes 100% electrical testing. This isn't just a smaller connector — it's a reliability upgrade for high-density automation.

Frequently Asked Questions — Honest Answers from Our Application Engineers
Q1: "100 mating cycles" seems low for daily changeovers. Is the M5 suitable?
The DIN spec is a conservative minimum. In real‑world use, our M5 series industrial connector consistently achieves 300–500 cycles while staying within contact resistance limits.
Q2: What torque ensures IP67 sealing without damaging the O‑ring?
- Fixing nut torque: 0.2–0.3Nm — hand‑tight plus a quarter‑turn with a small wrench. Over‑tightening stresses the O‑ring.
- O‑ring replacement: After 50–100 mating cycles for critical sealing applications.
- Cable bend radius: Minimum 5× cable diameter at the entry point.
- Mating force: Hand‑tight only — never use pliers to force the thread.
- Orientation: For washdown areas, point the cable exit downward to prevent pooling.
For aggressive chemicals (e.g., peracetic acid), we recommend PUR cable and annual O‑ring replacement as preventive maintenance.
