Why Choose the Finder 40.61.8.024.1001 Power Relay?

The Finder 40.61.8.024.1001 is a compact 16 A electromechanical power relay featuring a 24 V AC coil, single-pole changeover contacts (SPDT / 1 CO) and silver-nickel (AgNi) contact material. Part of the established Finder 40 Series, this miniature relay provides dependable switching for industrial automation, electrical control panels, machinery and electronic control equipment.

Designed for applications requiring reliable switching in a space-efficient format, the Finder 40.61.8.024.1001 combines a 16 A rated contact current, 250 V AC rated contact voltage and 4,000 VA AC1 switching capacity. Its changeover contact arrangement provides both normally open and normally closed switching paths, offering flexibility for control, signalling and load-switching circuits.

A distinguishing feature of this particular model is its RT III wash-tight construction, which offers enhanced protection against the ingress of liquids during suitable manufacturing and cleaning processes. Combined with its AgNi contacts, compact housing and compatibility with suitable Finder 95 Series sockets, the relay is a practical choice for OEM manufacturers, maintenance engineers and electrical panel builders.

Reliable 24 V AC Relay Switching for Industrial Automation

The Finder 40.61.8.024.1001 operates using a 24 V AC electromagnetic coil. When the coil is energised, the internal changeover contact transfers from its normally closed position to its normally open position. When the coil supply is removed, the relay returns to its normal state. This provides a straightforward method of controlling electrical loads and auxiliary circuits using a separate control signal.

The relay's SPDT contact configuration makes it useful for applications requiring changeover switching rather than a simple normally open output. Its 16 A contact rating and AgNi contact material support a range of compatible industrial control duties, while the compact housing makes it suitable for densely populated electrical assemblies.

The RT III wash-tight construction distinguishes this model from standard flux-proof relay variants. It provides additional protection during suitable PCB washing and manufacturing operations. However, wash-tight construction should not be interpreted as a waterproof rating for unrestricted exposure to liquids or outdoor environments. Installation and cleaning must follow Finder's handling recommendations.

Typical Applications

  • Industrial automation and machine control circuits.
  • Electrical control panels and switching assemblies.
  • PCB-mounted electronic control equipment.
  • OEM machinery and electrical equipment manufacturing.
  • Heating, ventilation and air-conditioning control circuits.
  • Industrial signalling and auxiliary control systems.
  • Electrical interlocking and changeover circuits.
  • Building automation and equipment control.
  • Control of suitably rated resistive electrical loads.
  • Equipment manufactured using compatible PCB washing processes.
  • Maintenance and replacement of compatible Finder 40 Series relays.

Does the Finder 40.61.8.024.1001 use a 24 V AC or 24 V DC coil?

This model uses a 24 V AC coil rated for 50/60 Hz operation. It is not the 24 V DC version. The relay has a nominal AC coil consumption of 1.2 VA and a nominal coil resistance of approximately 320 Ω.

What does the RT III wash-tight designation mean?

RT III wash-tight indicates that the relay has a construction intended to provide protection against liquid ingress during suitable manufacturing and cleaning processes. This is particularly useful for compatible PCB assembly operations. It does not mean the relay is suitable for continuous immersion or unrestricted exposure to water.

What is the contact configuration and rating of the Finder 40.61.8.024.1001?

The relay has one changeover contact (SPDT / 1 CO) rated at 16 A and 250 V AC, with a maximum switching voltage of 400 V AC. Its rated AC1 switching capacity is 4,000 VA. The actual permissible load depends on the switching category and electrical characteristics.

Can the Finder 40.61.8.024.1001 be installed in a relay socket?

Yes. The Finder 40.61.8.024.1001 can be mounted directly onto a suitable PCB or installed into a compatible Finder 95 Series relay socket. The relay has a 5 mm contact terminal pitch. Socket compatibility and wiring arrangements should be checked against Finder's documentation before installation.
