CVC VOICE COIL ACTUATORS WITHOUT GUIDING
The CVC series voice coil actuators don't incorporate a shaft or bearing system. The coil former is made of aluminium offers threaded holes for mounting the coil to the external mechanics which needs to provide the guidance for the coil assembly. The leads are connected to the wire inside of the coil former and the gap is then filled with epoxy to provide a stable and reliable connection.
- 15 sizes with 16 to 90mm diameter (bigger version available on request)
- continuous force range 1 to 120N
- stroke 5 to 40mm
- hollow shaft version available
