BEI Sensors announces the launch of the LP Series of heavy-duty rotary encoders that provide reliable and precise motion control feedback in a compact, low profile encoder package for harsh applications. 

  • Uses innovative sensing technology that allows for accurate position and speed sensing
  • Withstands extreme temperatures, shock and vibration, and wet and dirty environments
  • Three distinct encoder types are available in incremental or absolute single turn outputs - a compact version with cable or connector terminations, a terminal box option and an explosion proof model
  • Each version provides rugged and reliable motion control solution for a wide range of harsh applications in material handling, wind turbine, off-highway vehicle, and oil and gas industries
  • Heavy-duty design provides ingress protection rating of IP66 and protects internal components from exposure to the elements, making these encoders durable and well suited for dirty and dusty outdoor applications
  • Encapsulated electronics protect against humidity, make it vibration resistant up to 200 m/s2 (55 to 2,000 Hz) and shock resistant up to 3000 m/s2 (5ms half-sine), and enables operation in extreme temperatures from -40 to 100 C
  • Standard aluminum anodized housing resists corrosion and ensures long operational life 
  • Terminal box option simplifies installation and allows pre-wiring, preventing wiring errors
  • Termination style also comes standard with enhanced electronics providing overvoltage protection which prevents failure and saves automated systems from costly downtime
  • Advanced electronic design with terminal blocks contain especially robust output drivers that allow for the use of long cable runs with no loss of signal
  • Captive screws are standard to simplify installation and prevent loss of screws while mounting in tight, hard-to-reach places
  • Low profile design makes for easy installation into space-restricted applications where available shaft space is limited
  • Programmable option enables user to select any resolution from 1 to 10,000 PPR, adding to versatility in wide variety of applications 
  • Variety of mechanical configurations available including shafted, through shaft, blind shaft or shaft with integrated coupling to suit particular applications
