IDEC Force Guided Relays

IDEC Force Guided Relays are used in safety circuits to detect failures such as contact welding and damage to the contact spring. Contacts of a force guided relay are forced to open and close by a guide connected to the armature. Due to requirements of standard EN50205, a force guided relay has independent NO and NC contacts. If a NO contact welds, a NC contact will not close even when the relay coil is turned off (de-energized) and must maintain a gap of at least 0.5 mm. Furthermore, if a NC contact welds, a NO contact will not close when the relay is turned on (energized) and must maintain a gap of at least 0.5 mm.

  • Response time of 8ms ensures safety by turning the load off quickly (200 m/s² minimum).
  • Compact size enables size reduction of the PC board.
  • High shock resistance suitable for use in machine tools and in environments subjected to vibration and shocks.
  • Available with a built-in LED.
  • Force guided contact mechanism complies with international standards (EN50205 Type A TUV approved).
  • PC board mount and DIN rail mount sockets are available.
