Banner Engineering SI Series Safety Limit Switches

As an addition to Banner Engineering’s SI Safety Interlocking Switch family, the SI series of safety limit (position) switches expand the solutions for monitoring the position of a wide variety of guards, gates, covers, and other movable machine fixtures/tooling. These switches can be employed in interlocked guard safety applications because of the positive-opening design of the normally closed contacts (per IEC 60947-5-1). They can also solve simple position monitoring applications, such as end-of-travel and home-position.

Three new series have been introduced:

  • SI-LM40: die-cast aluminum housing and metal actuating systems provide a robust switch for the industrial environment.
  • SI-LS31: plastic body provides protective insulation and is resistant to many aggressive chemicals and liquids found in the industrial environment.
  • SI-LS83: compact, plastic body for confined spaces.
A wide variety of actuating systems and contact arrangements are available.
