SYRM 1.905 mm Pitch Rectangular PCB Connectors
1.905 mm pitch · 10–206 contacts · 55302 type
Rugged Rectangular PCB Connectors
Rectangular board-to-board and board-to-cable connectors for rugged electronics — 55302 type, DIN 41612 type, mixed power, zero insertion force and modular.
Rugged electronic units need board connectors that survive vibration and shock, carry both signal and power, and stay reliable over many mating cycles.
Our range covers SYRM (1.905 mm, up to 206 contacts), SYRMD with 13 A and 23 A power contacts, SYW and J55302 (MIL-DTL-55302 type) on a 2.54 mm grid, PDS and J18 (DIN 41612 type) with wire-spring sockets, CZ4 modular connectors to 50 A and 15,000 cycles, and DMK zero-insertion-force connectors.
