Features

Guard-locking door switch in plastic housing

The D4NL guard-lock safety door switches are available with four or five built-in contacts. When locked, they have a key holding force of up to 1300N. Mechanical lock/solenoid release types and vice versa set up the complete range in combination with various conduit types, e.g. M20.

  • Safety door switch with electromagnetic lock or unlock mechanism
  • Models with four or five built-in contacts
  • Strong key holding force: 1300N
  • For standard loads and micro loads
  • Keys are compatible with D4GL and D4NS
