Rotary Limit Switches


Rotary limit switches are electromechanical controls consisting of an input shaft, gear reducer, signal transmitter and limit or safety switches. If desired, encoders, resolvers, power interfaces or potentiometers can also be integrated (consult category POSITION Transducers for additional product information). These products are available in a range of configurations:

  • FRL90 are CE-approved in 90mm (3.5″) OD synchro cans for flange or servo mounting
  • KW series are open frame for integration in customer’s housing
  • DWG series are CE-approved combination Potentiometer + Limit Switches packaged in heavy duty NEMA-style rectangular housing
  • KWG series are CE-approved general purpose units packaged in heavy duty NEMA-style rectangular housing (NOTE: A 4-20mA position output option is available)
  • MR221/MR222 series are UL/cUL/CE-approved Heavy Duty NEMA-style rectangular units available in die cast aluminum or stainless steel housing
