Product Description

M12 cylindrical microswitches are used in potentially explosive atmospheres as position switches or as an additional safety element. Thanks to its compact housing and durability, the M12 type is ideal for many industrial applications.

The housing with an M12x1 thread allows for precise positioning, and the switch can be mounted directly into standard M12 inductive sensor holes.

Standard versions

  • For direct mounting on machines
    • With 3 x 0.5 mm² cable, 3 m
    • Item no.: 500027
  • For mounting inside Ex d-certified enclosures
    • With 3 x 0.5 mm² cable, 1 m
    • Item no.: 500026

Scope of delivery:

  • Switch with two M12 PA nuts
  • (Other cable lengths available upon request)

Design features

  • Precise position adjustment thanks to M12x1 thread
  • Actuator can be mounted directly or separately, can be completely concealed
  • Element made of corrosion-resistant stainless steel
  • Actuator is non-magnetic (does not affect inductive sensors)
  • Halogen-resistant cable, compliant with DIN VDE 0293-308
  • Wire color code: H05V-K 3 x 0.5 mm²
  • Wires with ferrules
  • Gold-plated contacts – suitable for low-voltage operation
  • Suitable for mounting in standard M12 sensor holes
