40.61.9.090.1303 Finder Miniature PCB relay 1pole 16A DC 90V

Why Choose the Finder 40.61.9.090.1303 Miniature Power Relay?

The Finder 40.61.9.090.1303 is a compact 16 A electromechanical power relay designed for industrial automation, electrical control systems and printed circuit board (PCB) applications. Part of the established Finder 40 Series, this miniature relay combines high-current switching capability with a space-saving design, making it suitable for control panels, machinery and electronic equipment.

Featuring a 90 V DC operating coil and a single changeover contact (SPDT / 1 CO), the Finder 40.61 provides flexible switching between normally open and normally closed circuits. Its electromechanical operation allows a relatively low-power control signal to switch an electrically isolated load circuit.

The Finder 40.61 relay family offers a 16 A rated contact current, 250 V AC rated switching voltage and 4,000 VA AC1 resistive switching capacity. The relay can be mounted directly onto a compatible PCB or installed using an appropriate Finder 95 Series relay socket, providing flexibility for original equipment manufacturers, electrical engineers and maintenance professionals.

Reliable Power Switching for PCB and Industrial Control Applications

The Finder 40.61.9.090.1303 operates using an electromagnetic coil and mechanically actuated changeover contact. When the specified 90 V DC control voltage is applied to the coil, the relay energises and transfers its common contact from the normally closed position to the normally open position. When the coil supply is removed, the relay returns to its normal, de-energised state.

This arrangement enables a control circuit to operate a separate electrical load without requiring the control signal to carry the full load current. The single changeover contact also provides flexibility for switching between two circuit paths, controlling auxiliary equipment or providing an electrical status signal.

The 40.61 relay design supports direct PCB mounting for compact electronic assemblies. Alternatively, a suitable Finder 95 Series socket can provide a plug-in installation arrangement, allowing easier relay replacement during equipment maintenance. Socket selection must account for the relay's pin configuration, current rating and installation requirements.

When selecting this relay, the 90 V DC coil voltage must be distinguished from the contact switching ratings. The permissible load depends on whether the circuit is resistive, inductive, motor-driven or subject to high inrush current. For the exact 40.61.9.090.1303 suffix configuration, contact material, environmental protection and any special approval requirements should be checked against the manufacturer's variant-specific documentation.
