Features

Limit switch with metal housing

The D4B series of limit switches in a rugged metal housing is suitable for both safety and non-safety applications due to its direct opening mechanism and TÜV approval. Furthermore with the increased temperature range and enhanced mechanical switching lifetime, the D4B is first choice for all applications from standard to demanding environments and for highest flexibility in mounting and connectivity preferences.

  • Direct opening mechanism and approval by notified body
  • Rugged metal housing and extended mechanical switching lifetime (snap action models)
  • Terminal block for direct wiring

1NO/1NC Contact (Snap-action)

If metal deposition between mating contacts occurs on the NC contact side, they can be pulled apart by the shearing force and tensile force generated when part B of the safety cam or plunger engages part A of the movable contact blade. When the safety cam or plunger is moved in the direction of the arrow, the Limit Switch releases.

1.The NC contacts provide the approved direct opening mechanism.D4B_rev02-1.png

2.For models with stainless steel rollers and temperature resistance of -40°C refer to WL-_-TC.

3.The values are acquired for an ambient temperature of 5 to 35°C and an ambient humidity of 40 to 70%.

4.-25 to 80°C for the flexible-rod actuator.
