Safety switch STP

Description

Based on the plastic-encapsulated safety switch TP with guard locking, the safety switch STP features both an actuating head and an internal cam made of metal. As a result, the switch can be used for applications that require high locking forces (up to 2500 N). The safety switch STP has a switching element with 4 switching contacts. EUCHNER supplies the STP safety switch with various contact combinations (positively driven contacts / NO contacts).

Dual-channel wiring to achieve the maximum possible safety level is possible with all possible variants. Given the particular property of the switching contacts of switching a minimum current of 1 mA, the safety switch STP is also suitable for use on safe control systems.

Features

  • Metal actuating head suitable for highest requirements
  • Two LED displays (optional) for the visual display of the door position and the position of the solenoid
  • Flexible connection options using three cable entries
  • High degree of protection IP67

Safety switch STP-BI

If persons are at risk of becoming unintentionally trapped in accessible danger areas, the EC Machinery Directive prescribes the following: “Machinery must be designed, constructed or fitted with a means of preventing a person from being enclosed within it or, if that is impossible, with a means of summoning help.”

The safety switch STP with bi-state function is used for the prevention of accidental locking-in inside the danger area. The guard locking always remains in its current position when electrically isolated (for example shut down of the system, power failure…) and meets the requirements on a guard locking device as per DIN EN ISO 14119:

  • The safety door remains either continuously locked after a loss of power, that is the user cannot enter the danger area at all
  • Or the safety door can be opened or closed as required, because the guard locking cannot be activated unintentionally due to locking of the guard locking pin

Safety switch STP-Extended

Safety switch with directly integrated controls and indicators

  • Guard locking, door unlock request, acknowledgment and start directly at the safety switch
  • Saving on external buttons and their wiring
  • Wide selection of different buttons, indicators, EMERGENCY STOP, key-operated rotary switches, etc.
