Why Choose the Finder 94.74.0SMA Relay Socket?
The Finder 94.74.0SMA is a relay socket from the Finder 94 Series, designed for use with compatible Finder plug-in industrial relays. It provides a practical interface between the relay and electrical control wiring, supporting organised installation, maintenance and replacement in industrial automation systems.
Designed for 4-pole changeover relay applications, the Finder 94.74.0SMA is associated with Finder's 55.34 industrial relay family. Its socket-based arrangement allows the compatible relay to be installed as a removable component rather than being permanently wired into the control circuit.
The 94.74.0SMA configuration is suitable for applications requiring multiple switching contacts, including control panels, machinery automation, signalling systems and auxiliary control circuits. The complete socket and relay combination must be selected according to the manufacturer's compatibility and electrical rating information.

Flexible 4-Pole Relay Switching for Industrial Control
Four-pole changeover relays are useful in automation systems where several circuits must be switched simultaneously using a single relay coil. Each changeover contact provides a common terminal, a normally open connection and a normally closed connection, allowing a suitably designed circuit to perform multiple switching functions.
The Finder 94.74.0SMA provides a socket interface for compatible Finder 55.34 relays, supporting the installation of removable industrial switching devices within electrical control systems.
A plug-in relay arrangement is particularly useful for equipment maintenance. When a compatible relay requires replacement, the relay can be removed from the socket without disconnecting the permanent control wiring, provided the circuit has been safely isolated.
The socket can be used in applications involving auxiliary contacts, equipment status signalling, control interlocking and machine automation. The actual switching performance depends on the relay installed and the electrical limits of the complete assembly.
Compatibility note: The Finder 94 Series includes different socket arrangements for different relay types. The 94.74.0SMA should be matched to the exact relay model, mounting arrangement and terminal configuration. The suffix must not be used alone to infer additional features such as coil voltage, protection circuitry or mounting accessories.
Typical Applications
- Industrial automation control panels.
- Four-pole relay switching circuits.
- Machinery control and interlocking.
- Auxiliary control and signalling circuits.
- PLC-controlled relay output systems.
- Electrical distribution and control cabinets.
- Building management and automation systems.
- OEM electrical equipment assemblies.
- Industrial monitoring and alarm circuits.
- Replacement of compatible Finder 94 Series relay sockets.

Frequently Asked Questions
What is the Finder 94.74.0SMA?
The Finder 94.74.0SMA is an industrial plug-in relay socket from the Finder 94 Series, intended for use with compatible 4-pole changeover relays.
Which relays are compatible with the Finder 94.74.0SMA?
The socket is associated with selected Finder 55.34 industrial relays. Compatibility should be confirmed using the complete relay and socket part numbers.
What does 4 CO mean?
4 CO means four changeover contacts, also described as 4PDT. A compatible relay can switch four separate changeover circuits through a common operating coil.
Does the Finder 94.74.0SMA include the relay?
The 94.74.0SMA is a relay socket. A compatible relay is required unless the supplier specifically offers a complete socket and relay assembly.
Can the relay be replaced without rewiring the socket?
Yes. A compatible plug-in relay can be removed from the socket without disconnecting the permanent wiring, provided the electrical circuit is safely isolated before maintenance.
Can the Finder 94.74.0SMA be used for industrial automation?
Yes. The socket can be used with a suitable relay in industrial automation, auxiliary switching, machine control, signalling and electrical panel applications.
Does the socket determine the relay coil voltage?
No. The operating coil voltage is determined by the installed relay and any applicable socket accessories. The correct electrical configuration must be selected for the control circuit.
What determines the maximum switching current?
The permissible switching current depends on the ratings of the socket, fitted relay, wiring and complete electrical installation. The lowest applicable rating must be respected.
Can another Finder 94 Series socket replace the 94.74.0SMA?
Only if the alternative socket has the correct relay compatibility, pin arrangement, terminal configuration and mounting requirements. Different Finder 94 Series models are not automatically interchangeable.
