Why Choose the Finder 45.71.7.009.1310 Miniature PCB Power Relay?

The Finder 45.71.7.009.1310 is a miniature electromechanical power relay from the Finder 45 Series, designed for industrial control equipment, printed circuit board assemblies and electrical switching applications. It combines a 9 V DC sensitive coil with a single normally open contact and a versatile PCB and Faston terminal arrangement.

Featuring a 1 NO (SPST-NO) contact configuration, the Finder 45.71 relay platform is designed for switching appropriately rated electrical loads. Its 16 A contact rating, compact construction and reinforced coil-to-contact insulation make it suitable for equipment requiring a dependable interface between low-voltage control electronics and higher-power circuits.

The 45.71.7.009.1310 configuration combines a sensitive DC coil, silver nickel (AgNi) contacts and the standard RT II flux-proof construction. The relay's combined PCB and Faston 250 connections provide installation flexibility for compatible electronic and electrical equipment.

Part-number verification note: The requested code, 45.71.7.009.1310, has not been independently confirmed as an exact catalogue listing. However, the Finder 45 Series manufacturer's ordering structure identifies the 1310 suffix as an AgNi, normally open, flux-proof configuration. The information below is based on that ordering structure and the published 45.71 series specifications. Confirm the complete code with Finder before procurement.

Key Advantages

  • 16 A miniature power relay for industrial and electronic switching applications.
  • 9 V DC sensitive coil for compatible low-voltage control circuits.
  • Single normally open contact for straightforward load switching.
  • Silver nickel contact material for suitable power-switching applications.
  • PCB and Faston 250 connections provide flexible electrical integration.
  • Reinforced coil-to-contact insulation supports safe equipment design.
  • 6 kV impulse withstand capability between the coil and contact circuit.
  • RT II flux-proof construction suitable for specified PCB soldering processes.
  • Monostable operation automatically opens the contact when coil power is removed.
  • Compact construction suitable for space-conscious control equipment.

Reliable 9 V DC Control of Industrial Electrical Loads

The Finder 45.71.7.009.1310 uses an electromagnetic coil to operate a single normally open contact. When the 9 V DC coil is energised, the contact closes, completing the connected load circuit. When the coil supply is removed, the contact returns to its open position.

This SPST-NO switching arrangement is useful in equipment requiring a low-voltage electronic control signal to operate a separate electrical load. Typical functions include auxiliary power switching, equipment enable circuits, heating control and industrial machinery control, provided the electrical characteristics of the connected load are within the manufacturer's limits.

The silver nickel contact configuration is suitable for appropriately rated power-switching applications. However, the relay's nominal 16 A rating should not be interpreted as a universal switching capacity for every load. Motors, solenoids, capacitive loads, lighting drivers and DC circuits may require additional derating, suppression or a different relay specification.

The Finder 45.71 platform provides reinforced insulation between the control coil and switched contact, including an 8 mm insulation distance and 6 kV impulse withstand rating. These characteristics help support electrical separation in suitably designed equipment, but the complete assembly must still meet the relevant safety and installation requirements.

Typical Applications

  • Industrial automation control boards.
  • 9 V DC-operated switching circuits.
  • Printed circuit board power-switching assemblies.
  • Industrial machinery auxiliary control.
  • Building automation equipment.
  • Heating and ventilation control circuits.
  • Electrical equipment enable and interlocking circuits.
  • Electronic control modules.
  • OEM industrial electrical assemblies.
  • Power supply control equipment.
  • General-purpose electrical load switching within rated limits.
  • Maintenance of compatible Finder 45 Series installations.

Frequently Asked Questions

What is the Finder 45.71.7.009.1310 used for?

The Finder 45.71.7.009.1310 is a miniature electromechanical relay configuration intended for switching electrical loads using a low-voltage DC control signal. The 45.71 platform is used in industrial control equipment, electronic assemblies and PCB-based power-switching applications.

What coil voltage does the Finder 45.71.7.009.1310 require?

The part-number structure specifies a 9 V DC nominal coil. A suitable DC supply and coil driver must be provided, with the exact coil characteristics confirmed against the applicable manufacturer documentation.

What is the contact configuration of the Finder 45.71.7.009.1310?

The ordering code specifies one normally open contact (1 NO / SPST-NO). The contact closes when the relay coil is energised and opens when the coil is de-energised.

What is the contact current rating of the Finder 45.71 relay?

The Finder 45.71 relay platform has a 16 A rated contact current. The actual permissible switching load depends on voltage, load characteristics, ambient temperature and the manufacturer's applicable ratings.

What contact material does the 1310 configuration specify?

According to the Finder 45 Series ordering structure, the 1310 suffix specifies silver nickel (AgNi) contacts, a normally open contact arrangement and an RT II flux-proof construction.

How is the Finder 45.71 relay connected?

The Finder 45.71 is designed with a combination of through-hole PCB connections and Faston 250 terminals. The exact connection arrangement and PCB footprint should be checked against the manufacturer's dimensional and wiring diagrams.

What is the difference between RT II and RT III relay protection?

RT II refers to a flux-proof relay construction, while RT III identifies a wash-tight construction suitable for specified PCB washing processes. The requested 1310 configuration uses the RT II designation and should not be assumed to be wash-tight.
