The LP Series rotary encoder product family is built to withstand extreme temperatures, shock and vibration, and wet and dirty environments. This industrial encoder line provides reliable and precise rotary motion control feedback via a compact, low profile encoder package for harsh duty environment applications.

LP Series Encoders Product Review by Design World

LP Series Overview

  • Three LP Series encoder types are available to fit a variety of system needs:
Compact Terminal Box Explosion Proof
HHU9 HHUB HHUX
  • Each of the three encoder model types is available in incremental or absolute single turn outputs. The compact version comes with either a cable or connector termination . 


  • The compact version comes with either cable or connector terminations.

  • The terminal box version features enhanced electronics which makes it resistant to wiring errors.

  • All LP Series encoder models provide a rugged and reliable motion control solution for a wide range of harsh environments and are ideal for use in these industries:
    • Material handling
    • Metal process
    • Wind turbine
    • Off highway vehicle
    • Elevator
    • Agriculture
    • Oil and gas
    • Building automation

 


Mechanical Options

A variety of mechanical encoder configurations are available including shafted, through shaft, blind shaft or shaft with integrated coupling to fit a wide range of installations.
