Bistable actuator

Why you might need the Bistable linear actuator

The direct drive linear bistable actuator can be used to shift camshafts of various groove distances for cylinder deactivation or discrete variable valve lift applications. This improves the engine’s performance and reduces CO2 emissions.
Our actuator is the reference single bobbin, bistable solution on the market, featuring high switching speed in a compact design. It applies a stable force to the pins during their entire travel. This dual-pin actuator features fixed magnets which accentuate its simple, robust design.

This ensures lifelong reliability and constant performance in the demanding operating conditions close to the internal combustion engine.
