JS1-24V-F Panasonic JS Power Relay – 1 Form C, 10 A, 24 V DC Coil, Sealed
The Panasonic JS1-24V-F (Panasonic part number AJS1312F) is a cubic PCB power relay from the JS series. It has one changeover contact (1 Form C) rated up to 10 A and a 24 V DC single-side-stable coil drawing 360 mW. Its sealed construction allows automatic washing after soldering, and its compact cubic body weighs only about 12 g. JS relays were widely used in home appliances, office equipment, vending machines and industrial control boards. Panasonic has discontinued the JS series, and the JS1-24V-F is supplied as a direct replacement for PCBs and equipment already in service.
