High Performance Space

This custom linear actuator is designed for use in vacuum or shallow underwater. The actuator has a 1.25-inch stroke length, a custom 200W brushless DC motor with a power-off brake, high-load ball bearing nut with a 0.125″ pitch, and a total gear reduction of 6.24:1. This actuator also includes an integrated version of Ultra Motion’s Phase Index® digital absolute position encoder with a 0-5V analog output. This encoder provides robust high-speed position feedback reliably and over a wide temperature range. An internal linear potentiometer is also included for redundant position feedback. The actuator is fully shielded against EMI, and has D38999 interface connectors. Contact Us for more information.
