Linear Voice Coil Actuator delivers peak force of 0.5 lb.
Mechanical Power Transmission

Linear Voice Coil Actuator delivers peak force of 0.5 lb.

With an outside diameter of 0.375 in., Model LAH04-10-000A features an operating stroke of 0.157 in. The moving magnet design offers optimized heat dissipation. By allowing the magnet to move and keeping the coil fixed, any heat generated by the coil assembly can be conducted away. No moving wires and high heat dissipation makes this VCA best suited for high duty cycle applications such as pick...
