| The HAT Latching Relay is a heavy duty, single-coil latching relay, capable of switching 40 amps. The KLT Latching Relay is a highly reliable, miniature, single-coil latching relay; capable of switching up to 15 amps. These energy saving relays require no current to maintain contact closure, once the relay has been switched. To unlatch, simply reverse the polarity of the coil voltage. Save energy by implementing one of these latching relays into your system.

Remark:
1) In case of no tolerance shown in outline dimension: outline dimension <1mm. tolerance should be +/-0.2mm; outline dimension >1mm and <5mm. tolerance should be +/-0.3mm; outline dimension >5mm. tolerance should be +/-0.4mm.
2) The tolerance without indicating for PCB layout is always +/-0.1mm. |
Notice
1. Relay is on the “reset” or “set” status when being released from stock, with the considerationof shock risen from transit and relay mounting, relay would be changed to “set” or “reset” status, therefore, when application (connecting the power supply), pleasereset the relay to “set” or “reset” status on request.
2. In order to maintain “set” or “reset” status, energized voltage to coil should reach the rated voltage, impulse width should
be 5 times more than “set” or “reset” time. Do not energize voltage to “set” coil and “reset” coil simultaneously; and also
long energized time (more than 1 min.) should be avoided.
