Latching Solenoids
From automotive to aerospace, our solenoids power critical applications across industries worldwide. Experience the difference precision engineering makes.
Latching Solenoids (DC) — No-Power Hold, Reverse-Polarity Release
Guardian’s DC latching solenoids provide bistable actuation that holds position with zero continuous power, reducing heat and energy draw in battery-powered or always-on equipment. The plunger seats to the pole face at a specified holding force and stays latched through power interruptions; reverse the polarity to release. Standard units are UL Recognized and RoHS-compliant (2011/65/EU), with rapid customization for voltages, plungers, mounting, terminations, and value-added packages. 100% Made in the USA.
