Product Details
The M19 5‑pin model uses Φ2.0mm copper‑alloy power contacts delivering 15A together with additional smaller signal contacts in hybrid configurations. The push‑locking, anti‑vibration design provides reliable mating retention. The housing is fully sealed to IP67, rated UL94‑V0 for flame retardancy, and operates across a wide temperature range (-40°C to 105°C). Certified to ISO9001, CE, UL, TUV and RoHS.
