8.MB series maintained linear electromagnets
3 sizes available, each in several versions.
Pulse supply. Core activates when powered up (+ red wire); held in retract position by magnetic locking, with power off. Unlocks by reverse polarity with a minimum pulse of 50 → 100 ms.
Linked to a return system (spring, earth, etc.), this type of electromagnet ensures 2 stable positions with the power off (bistable).
Recommended for applications requiring 2 stable states without consumption. For example: mechanical memory function, improving the service life of battery-powered systems.
