RY2KS Series — Miniature Magnetic Latching Relays

Key features of the RY2KS series include:

• Standard “ice cube” base, solder lug (14-pin) termination

• Operates by pulse input and maintains condition even
during power failure

• High vibration and shock resistance

• Excellent self-holding performance

• Optional manual check button for circuit testing

• DIN rail, surface, and panel mount sockets
available for a wide range of mounting applications
