Technical Specifications Coil: dual set/reset winding, 24 V DC pulse; Contact configuration: SPDT; Contact rating: 8 A resistive at 250 V AC; Operate pulse width: ≥ 20 ms; Holding power: 0 W continuous; Operating temperature: -40 °C to +70 °C; Enclosure rating: IP20; Vibration withstand: 10 g peak without false operation.
Functional Features Permanent magnet latching mechanism; independent set and reset control; zero holding power consumption; vibration-resistant contact retention; LED status indication; DIN rail mountable.
Application Scenarios State-retention control circuits, energy-saving automation systems, power-off memory interlocks, low-power remote sites, battery-backed control systems.
Performance Parameters Contact bounce: < 3 ms; Operate time: < 15 ms; Reset time: < 15 ms; contact life: > 500,000 operations.
Material Composition Flame-retardant plastic housing; permanent magnet latching assembly; dual copper coil winding; silver alloy contact material; mounting hardware.
Structural Characteristics DIN rail mount form factor; front panel status indicator LED; rear set/reset and load terminal block.
Working Principle A set pulse energizes the set coil, pulling the armature into contact and latching it via permanent magnet. A reset pulse energizes the reset coil to release the contact. State is maintained with no coil power.
Installation Requirements Mount on standard DIN rail; wire separate set and reset pulse circuits; verify initial contact state before commissioning; test latching and release function.
