RS PRO SPNO 12 V DC Latching Relay, 50 A PCB Mounting


Need to switch a large current flow? This SPNO (single-pole, normally-open) latching relay from RS PRO uses a low-current pulse to activate the switch and will hold its position once actuated. The 3 W set and reset coils should not be energised at the same time and not for more than one minute.
This component is designed for mounting to a PCB (printed circuit board). Latching relay systems of this kind are commonly found in industrial counting and sorting systems, HVAC (heating, ventilation and air-conditioning) units and industrial cleaning equipment.
