D4B Limit switches
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 life-
time,theD4B is first choice for all applications from standard to demanding environ- ments and for highest flexibility in mountingand connectivity preferences.
• Direct openingmechanismand approval by notifiedbody
• Rugged metal housing and extended mechanical switching lifetime
(snap action models)
• Terminal block for direct wiring

1NO/1NC Contact (Snap-action)
If metal deposition betweenmating contacts occurs on the NC contact side, they can be pulled apart by the shearing force and tensile force generatedwhen 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.
