40.61.9.090.0303 Finder Miniature PCB relay 1pole 16A DC 90V

Why Choose the Finder 40.61.9.090.0303 Electromechanical Relay?

The Finder 40.61.9.090.0303 is an electromechanical relay from the Finder 40 Series, designed for electrical switching, industrial automation and electronic control applications. Featuring a 90 V DC coil and a single changeover contact, this relay enables a compatible DC control circuit to operate a separate electrical switching circuit.

The Finder 40.61 relay configuration provides a 16 A nominal contact rating, making it suitable for switching appropriately rated electrical loads. Its single-pole changeover arrangement offers both normally open and normally closed contact functions, providing flexibility for control, signalling and equipment interface applications.

Designed for integration into compatible printed circuit board assemblies, the Finder 40.61.9.090.0303 provides a compact switching solution for OEM equipment manufacturers, control system designers and maintenance engineers. The complete part number identifies a specific relay variant, so the manufacturer's technical documentation should be consulted to confirm its detailed coil characteristics, contact materials and electrical performance before installation or replacement.

Electromechanical Switching for Industrial Control and Automation

Electromechanical relays provide an effective method of interfacing electronic control circuits with external electrical loads. The Finder 40.61.9.090.0303 uses a 90 V DC operating coil to actuate a single changeover contact, allowing compatible control equipment to switch or signal through an electrically separate contact circuit. This makes the relay suitable for equipment designed around a 90 V DC control supply.

The 16 A nominal contact rating provides switching capability for appropriately rated loads, while the changeover configuration supports both normally open and normally closed circuit arrangements. Engineers should verify the intended switching voltage, load type, inrush current, electrical endurance and relevant contact derating against Finder's technical documentation. For replacement applications, the full 40.61.9.090.0303 part number should be checked rather than relying solely on the relay series or contact rating.
