High-Resolution Closed-Loop DC-Mike & Stepper Actuators

High-Resolution Closed-Loop DC-Mike & Stepper Actuators

Physik Instrumente

  • Catalog Number: M-230
  • Description: M-230 are ultra-high-resolution linear actuators providing linear motion up to 25 fmm with sub-micron resolution in a compact package. They consist of a micrometer with non-rota-ting tip driven by a 2-phase stepper motor or a closed-loop DC motor/gearhead combination with motor-shaft-mounted, high-resolution encoder (2048 counts/rev.).

    Non-Rotating Tip
    Compared to conventional rotating-tip micrometer drives, the non-rotating-tip design offers several advantages:

    • Elimination of torque-induced positioning errors
    • Elimination of sinusoidal motion errors
    • Elimination of wear at the contact point
    • Elimination of tip-angle-dependent wobble
    M-230 actuators provide a cost-effective solution for heavier-duty industrial and OEM environments. They feature extremely low-stiction, low-friction construction, allowing for minimum incremental motion as low as 50 nanometers and speeds up to 1.5 mm/sec.

    Non-Contact Limit and Origin Switches
    Integrated, non-contact, high-precision Hall-effect origin and limit switches protect your equipment and increase versatility in automation applications.

    NIntegrated Line Drivers
    M-230 actuators include an integral 0.5 m cable with 15-pin sub-D connector and a 3 m extension cable. On the DC-servo versions, the connector features integrated line drivers for cable lengths up to 10 meters between actuator and controller.

    A screw-in ball tip and a flat tip are included.

    • 10 & 25 mm Travel Range
