Why Choose the Finder 40.61.6.024.1000 Bistable PCB Relay?

The Finder 40.61.6.024.1000 is a miniature 16 A bistable electromechanical relay designed for industrial automation, electrical control equipment and electronic switching applications. Part of the Finder Series 40, it combines a compact housing, a single changeover contact and a mechanically maintained switching mechanism that retains its selected position without continuous coil energisation.

Featuring a 24 V AC/DC single-coil bistable operating system and 1 changeover contact (1 CO / SPDT), the relay provides a practical solution for applications requiring maintained switching states. Its 16 A rated contact current and 250 V AC rated contact voltage support the switching of compatible electrical loads within the manufacturer's specified limits.

The Finder 40.61.6.024.1000 is designed for direct PCB mounting or installation using compatible Finder Series 95 sockets. Its miniature construction, 5 mm contact pin pitch and single-coil bistable technology make it suitable for compact electrical assemblies, automation equipment and control circuits where reduced holding power is desirable.

Reliable Bistable Switching for Industrial Control and Automation

The Finder 40.61.6.024.1000 uses a single-coil bistable mechanism that allows its contacts to remain in either of two mechanically maintained switching positions. Unlike a conventional monostable relay, the bistable mechanism does not require continuous coil energisation to retain the selected contact state.

The relay is operated using suitable SET and RESET control circuits. In the Finder Series 40 bistable arrangement, the control circuit applies the appropriate magnetising or demagnetising action to change the relay's state. The manufacturer's wiring diagram specifies the required connections and external components for AC or DC operation. The minimum SET or RESET impulse duration is 20 ms, and the control arrangement must prevent simultaneous SET and RESET commands.

Its single changeover contact provides a common terminal and two alternative switching paths. This makes the relay suitable for maintained control functions, circuit selection and applications where a switching state must remain established after the operating signal has ended.

With a 16 A rated contact current, the relay supports suitable resistive and industrial control loads. The connected equipment must remain within the relevant Finder ratings, particularly where inductive loads, motors, LED drivers or other devices produce significant switching inrush currents.

The compact 29 × 12.4 × 25 mm housing allows the relay to be incorporated into printed circuit board assemblies or used with compatible Finder Series 95 sockets. This flexibility supports both electronic equipment manufacture and control cabinet applications requiring mechanically maintained switching.

What coil voltage does the Finder 40.61.6.024.1000 require?

The relay has a 24 V AC/DC nominal operating voltage. It must be connected using the appropriate Finder bistable SET and RESET wiring arrangement for the selected supply type.

What is the rated switching current?

The Finder 40.61.6.024.1000 has a 16 A rated contact current and a 250 V AC rated contact voltage. Actual load compatibility depends on the applicable switching category and electrical characteristics.

What contact configuration does this relay have?

The relay features one changeover contact (1 CO / SPDT), providing a common terminal and two alternative switching paths.

Is the Finder 40.61.6.024.1000 a latching relay?

Yes. It is a single-coil bistable relay, also described as a latching relay. Its contacts remain in their selected mechanically maintained position after the operating impulse ends.

Does the relay require continuous coil power?

No. The relay uses a bistable mechanism, so continuous coil energisation is not required to maintain its selected contact position. Appropriate SET and RESET control signals are used to change the state.

How are the SET and RESET functions controlled?

The Finder Series 40 bistable design uses an appropriate external control circuit to magnetise or demagnetise the relay mechanism. AC and DC operation use different wiring arrangements, so the manufacturer's relevant connection diagram must be followed.

What is the minimum SET or RESET impulse duration?

The minimum SET or RESET impulse duration is 20 ms. The control circuit must also prevent simultaneous operation of the SET and RESET commands.

Can this relay be mounted directly onto a PCB?

Yes. The Finder 40.61.6.024.1000 supports through-hole printed circuit board mounting and uses a 5 mm contact pin pitch.

Can the Finder 40.61.6.024.1000 be used with a relay socket?

Yes. Finder Series 40 relays can be installed using compatible Finder Series 95 sockets. Socket selection must account for the relay's pin arrangement, switching ratings and bistable control requirements.

What is the difference between the Finder 40.61.6.024.1000 and 40.61.6.012.4000?

Both belong to the Finder Series 40 single-coil bistable relay family and use a 16 A single changeover contact. The 40.61.6.024.1000 is a 24 V AC/DC version, while the 40.61.6.012.4000 is a 12 V AC/DC version. Their complete suffixes should also be checked against the applicable manufacturer ordering specifications before substitution.
