Schneider Electric CA2DK122FA60 Latching Relay

Schneider Electric CA2DK122FA60 is a mechanical-latching relay accessory in the TeSys CA2/DK family, designed to be paired with Schneider Electric CAD control relays and LAD6K latch blocks in industrial control panels. The unit uses an 110–120 VAC coil (A60 family), compatible with 50/60 Hz supply, to set or reset the latch when a momentary control signal is applied. Once energized for the appropriate pulse, the device retains its contact state without continuous coil current, providing energy-efficient, memory-type control for auxiliary circuits. It is typically used to implement memory functions in automation applications, such as maintaining a contactor’s latch state in start/stop circuits, sequencing, and interlock logic, when integrated with the CAD/TE connectivity ecosystem. The CA2DK122FA60 is part of Schneider Electric’s older CA2DK line, which historically paired with mechanical latch blocks for robust, modular control relays; in some markets these devices have been phased into TESYS D solutions, so check compatibility with current CAD control relays and latch blocks for new designs. For best results, match the coil voltage (110–120 V AC, 50/60 Hz) and mount in designed enclosures or DIN-rail compatible assemblies using the appropriate CAD/LAD accessories.
