Specification note: Product-specific supplier records confirm the 24 V DC sensitive coil, 10 A DPDT contacts, AgNi contact material, 1.15 kΩ coil resistance, 0.5 W consumption, switching times and operating temperature range. The standard Finder Type 40.62 switching and insulation ratings must still be applied according to the relevant load category, ambient conditions and current manufacturer datasheet.
24 V DC Sensitive Coil for Low-Power Industrial Control
The Finder 40.62.7.024.0000 uses a 24 V DC sensitive coil, identified by the 7.024 section of its manufacturer ordering code.
The sensitive coil has a nominal resistance of 1150 Ω and draws approximately 21 mA at its rated voltage, corresponding to a nominal power consumption of approximately 0.5 W.
This makes the relay suitable for applications where the available control power is limited or where minimising power consumption is desirable.
The relay's specified must-operate voltage is 17.5 V DC. The control circuit should nevertheless be designed around the rated 24 V DC supply, with suitable allowance for supply tolerance, voltage drop and operating temperature.
The sensitive coil can be operated using an appropriately rated PLC output, transistor, MOSFET or dedicated relay-driver circuit.
When using semiconductor outputs, appropriate coil transient suppression should be considered. A flyback diode or other suitable suppression device can protect the driver against inductive voltage spikes, although the chosen suppression method may affect relay release time.
The 2 CO / DPDT configuration is one of the defining features of the Finder 40.62.7.024.0000.
It provides two separate changeover contact sets, each consisting of:
- Common (COM): The shared switching terminal.
- Normally closed (NC): Connected to common when the relay is de-energised.
- Normally open (NO): Connected to common when the relay is energised.
When the 24 V DC coil is energised, both common contacts transfer from their normally closed positions to their normally open positions.
When coil power is removed, both contact sets return to their normal positions.
This allows a single control signal to switch two electrical circuits simultaneously, supporting equipment changeover, control interlocking, paired signalling and dual-output applications.
Although the two contact sets are electrically separate, they are mechanically operated by the same coil and cannot be controlled independently.
10 A Switching Capability for Compatible Electrical Loads
The Finder 40.62.7.024.0000 has a 10 A rated contact current and a 250 V AC rated contact voltage.
The Type 40.62 family provides a rated resistive-load switching capacity of 2500 VA AC-1.
However, the actual permissible switching load depends on the electrical characteristics of the connected equipment.
- Resistive loads: Typically have relatively predictable steady-state current.
- Motors: Can draw high starting currents and produce inductive switching transients.
- Transformers: May generate substantial magnetising inrush currents.
- Solenoids and contactor coils: Require consideration of inductive load ratings.
- LED drivers: May produce high short-duration charging currents.
- Capacitive circuits: Can create high inrush currents when energised.
For these applications, the relay should be selected using the relevant Finder load ratings and electrical-life information rather than relying solely on its nominal 10 A rating.
The Finder 40.62.7.024.0000 uses silver nickel (AgNi) contact material.
AgNi contacts are widely used in general-purpose electromechanical relays because they offer a practical balance of electrical conductivity, mechanical durability and switching performance.
They are suitable for many control and power-switching applications within the relay's specified ratings.
However, the contact material must be matched to the electrical load. High-inrush applications and very low-level signal circuits may require additional consideration or an alternative contact specification.
The complete .0000 ordering suffix should therefore be retained when specifying an exact replacement.
Electrical Isolation Between Coil and Contacts
The Finder Type 40.62 provides substantial electrical separation between the low-voltage control coil and the switched contact circuits.
The standard Series 40 insulation design includes 8 mm coil-to-contact creepage and clearance and a 6 kV impulse withstand voltage.
These characteristics support equipment designs where a 24 V DC control circuit must switch separate electrical loads.
The complete installation must still satisfy applicable electrical safety requirements, including PCB layout, insulation coordination, conductor sizing, protective devices and enclosure design.
Compact PCB and Plug-In Socket Mounting
The Finder 40.62.7.024.0000 features a compact relay body measuring approximately 29 × 12.4 × 25 mm.
Its compact construction makes it suitable for electronic equipment where space is limited.
The relay can be installed directly on a suitable printed circuit board or used with compatible plug-in socket arrangements.
Selected Finder Series 95 sockets offer additional mounting flexibility, including DIN rail installation where the correct socket is specified.
When designing a PCB footprint or selecting a socket, always check the manufacturer's terminal drawing and confirm that the socket's electrical ratings are appropriate for the intended load.
The relay is listed with a flux-protected enclosure, intended to reduce flux penetration during suitable soldering processes. This should not be interpreted as permission for unrestricted PCB washing.
