Reliable Electromechanical Power Switching for Industrial Equipment

Electromechanical power relays such as the Finder 40.61.7.012.4020 allow a low-voltage control circuit to switch a separate electrical load using an electromagnetic coil and mechanical contacts. When the 12 V DC coil is energised, the internal changeover contact transfers between its normally closed and normally open positions. This provides flexible control of compatible AC and DC circuits while maintaining electrical separation between the coil and switching contacts.

The Finder Series 40 relay family is designed for compact electronic equipment, industrial automation assemblies and control applications requiring dependable electromechanical switching. The 40.61.7.012.4020 combines a high-current changeover contact, sensitive DC coil and compact housing with PCB and socket installation options. Its silver-tin oxide contact material and mechanical durability make it suitable for appropriately rated power switching and auxiliary control duties.

Typical Applications

  • Industrial automation and machine control equipment.
  • PCB-mounted electrical control circuits.
  • Industrial power switching and auxiliary control systems.
  • Heating, ventilation and air conditioning control equipment.
  • Electrical control panels and electronic assemblies.
  • Lighting and signalling control circuits.
  • Power supply and electrical distribution control equipment.
  • Industrial machinery and manufacturing automation.
  • OEM electronic equipment and control board manufacturing.
  • Compatible AC and DC load switching applications.
