Product Information

The ZJ41F is an ultra-thin (5 mm wide) plug-in power / interface relay — 28 × 5 × 15 mm, just ~5 g — with one SPDT (1 Form C) Ag-alloy contact rated 6 A at 250 V AC / 30 V DC. High sensitivity (coil ~0.17 W), 4 kV coil-to-contact isolation (6 kV surge), UL Class A insulation and VDE 0700/0631 reinforced insulation — for high-density PLC I/O, control boards and interface modules.
