Why Choose the Finder 40.61.7.012.4021 Miniature Power Relay?

The Finder 40.61.7.012.4021 is a compact and reliable miniature electromechanical power relay designed for switching electrical loads in industrial automation, control panels and electronic equipment. As part of the established Finder 40 Series relay range, it combines a high-current changeover contact with a sensitive DC coil, making it suitable for applications requiring dependable switching from low-power control signals.

This relay features a single changeover contact (1 CO / SPDT) with a rated switching current of 16 A and a nominal contact voltage of 250 V AC. Its 12 V DC sensitive coil enables operation from compatible low-voltage control circuits, while the changeover contact provides normally open and normally closed switching functionality.

The Finder 40.61.7.012.4021 belongs to the 40.61 relay family, which features a compact construction, high electrical isolation between coil and contacts, and compatibility with suitable Finder 95 Series sockets. The relay family is designed for industrial switching applications where reliable operation, compact dimensions and convenient integration are important.

Key Advantages

  • Compact 16 A miniature power relay for industrial and electronic control applications.
  • 12 V DC sensitive coil suitable for low-voltage control circuits.
  • Single changeover contact (SPDT) for flexible switching arrangements.
  • 250 V AC nominal contact rating for compatible electrical loads.
  • Maximum switching voltage of 400 V AC under specified operating conditions.
  • 6 kV impulse withstand voltage between coil and contacts in the 40.61 series.
  • Compact design supports efficient use of space in electrical equipment.
  • Compatible 40.61 relay variants can be used with Finder 95 Series relay sockets.
  • Suitable for automation, control equipment and electrical switching systems.

Key Features

  • Finder 40 Series miniature electromechanical relay.
  • 40.61 single-pole power relay configuration.
  • 12 V DC sensitive coil.
  • 16 A rated contact current.
  • 1 CO (SPDT) changeover contact.
  • 250 V AC rated contact voltage.
  • 400 V AC maximum switching voltage.
  • 30 A maximum peak contact current for applicable 40.61 contact configurations.
  • 4,000 VA rated AC1 switching load.
  • 0.55 kW single-phase motor rating at 230 V AC.
  • 5 mm contact pin pitch.
  • High coil-to-contact insulation with 8 mm creepage and clearance distances.
  • Compact relay body measuring approximately 29 × 12.4 × 25 mm.
  • Designed for use in industrial control and automation systems.

Reliable Electrical Switching for Industrial Automation

Electromechanical relays such as the Finder 40.61 provide an effective method of controlling electrical loads using low-voltage signals. When the relay coil is energised, the changeover contact transfers between its normally closed and normally open positions, allowing compatible control circuits to operate external electrical equipment.

The Finder 40.61 relay family is designed for applications requiring a compact switching component with a relatively high contact current rating. Its 16 A changeover contact makes the series suitable for a variety of resistive and appropriately rated inductive loads, including control circuits, lighting equipment and small motor-control applications.

With high electrical isolation between the coil and contacts, the 40.61 series supports separation of low-voltage control electronics from switched load circuits. This makes the Finder 40.61.7.012.4021 a practical choice for compatible industrial automation equipment, electronic controllers and electrical panel assemblies.

Typical Applications

  • Industrial electrical control panels.
  • PLC and electronic controller output switching.
  • Machine automation and production equipment.
  • Low-voltage control circuit interfacing.
  • Lighting and electrical load switching.
  • Small motor and auxiliary equipment control.
  • Power management and electrical distribution equipment.
  • OEM electronic assemblies and control systems.
  • Building automation and electrical control installations.
