Thorlabs’ Motorized Actuators are designed for use with optical positioning devices. They offer high resolution in lightweight packages, which makes these actuators ideally suited for demanding optical automation applications. These 1″ (25 mm) travel motorized actuators are available with three drive types: 2-phase stepper motors, DC servos with encoders, or piezo inertia actuators. Vacuum-compatible models with DC servos or piezo inertia actuators provide functionality down to 10^-6 Torr. See the table to the right for an overview of the available models or below for more details.

Z925BV Actuator

The vacuum-compatible cable integrated with the Z925BV actuator is terminated in a female IDC 10-Pin socket connector. A short converter cable, which adapts this female IDC socket connector to a D-type male HD15 pin connector, is included with the Z925BV actuator to facilitate connecting it to the recommended KDC101 controller. This converter cable, whose terminating connectors are shown below, is not vacuum compatible.  Information describing the pin assignments for both the female IDC socket and male D-type HD connector (when it is connected to the female IDC socket connector) follows.
