High Shock Resistance High shock resistant suitable for use in machine tools and in PC board mount DIN rail mount 2 environments subjected to vibration and shocks. (200 m/s minimum) Counter-electromotive force diode model Clear Visiblilty The diode protects the operating coil circuit from counter electromotive force when the relay is denergized. Available with a built-in LED. What is a force guided relay Relays 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 NO NC NO NC contact contact Guide Armature contact contact Guide Armature De-energized Energized connected to the armature. (Normal (Normal Due to requirements of standard EN50205, a force guided relay has independent Condition) Condition) 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. (General-purpose relays do not have the above characteristics.) NO contact A gap of at least A gap of at least NC contact De-energized is welded 0.5 mm is maintained Energized 0.5 mm is maintained is welded (Abnormal (Abnormal NC contact Guide Condition) Condition) NO contact Applications Force guided relays are used in safety circuits in combination with interlock switches, light curtains, and emergency stop switches to control outputs. They can also be used to expand outputs for safety relay modules and safety controllers.
