Finder 94.72.0SMA Relay Socket – DIN Rail Mounting, Screw Terminals and Metal Retaining Clip
The Finder 94.72.0SMA is an industrial plug-in relay socket from the Finder 94 Series, designed to provide a convenient mounting and wiring interface for compatible Finder relays. It is suitable for electrical control panels, industrial automation systems, machinery control circuits and other installations requiring a removable relay arrangement.
Featuring screw terminal connections, a DIN rail mounting arrangement and a metal retaining clip, the Finder 94.72.0SMA supports secure relay installation and straightforward maintenance. Its modular construction allows the compatible relay to be removed or replaced without disconnecting the permanent wiring from the socket, provided the circuit has first been safely isolated.
The socket forms the connection between the external control wiring and the installed relay. The relay itself supplies the operating coil and switching contacts, so the electrical behaviour of the completed assembly depends on the exact relay selected.
Important: The Finder 94.72.0SMA is a relay socket, not a complete switching relay. The compatible relay must be selected separately, and its pin arrangement, coil voltage and contact ratings must be checked against the manufacturer's documentation.

How the Finder 94.72.0SMA Relay Socket Works
The Finder 94.72.0SMA acts as an electrical and mechanical interface between a compatible plug-in relay and the external wiring of a control circuit.
During installation, the socket is mounted in the electrical cabinet and the appropriate conductors are connected to its screw terminals. A compatible relay is then inserted into the socket, allowing its pins to connect with the corresponding socket terminals.
When the installed relay receives its specified coil supply, its contacts operate according to the relay's design. These contacts can be used to control suitably rated electrical loads, provide auxiliary switching or interface with other control equipment.
The socket itself does not generate the switching action. It provides the mounting and wiring interface, while the installed relay determines the electrical switching characteristics.
Metal Retaining Clip for Secure Relay Installation
The Finder 94.72.0SMA incorporates a metal retaining clip to help hold the compatible plug-in relay securely in its socket.
This mechanical retention is useful in industrial electrical panels where components may be subject to routine maintenance activity or equipment movement.
The retaining clip also helps reduce the risk of accidental relay displacement. When the relay requires replacement, the clip can be released in accordance with the manufacturer's instructions.
The retaining clip is a mechanical accessory and should not be interpreted as evidence of a particular vibration certification or safety approval for the completed assembly.
Screw Terminal Connections
The socket uses screw terminal connections for the external electrical wiring. This provides a familiar installation method for industrial electricians and control panel builders.
Correctly prepared conductors are inserted into the designated terminals and secured according to the manufacturer's wiring instructions.
The appropriate conductor cross-section, stripping length and tightening torque must be confirmed using the current Finder technical documentation for the exact socket.
Care should also be taken to identify the correct coil and contact terminal positions for the selected relay.
DIN Rail Installation and Maintenance
The Finder 94.72.0SMA is intended for mounting within a suitable electrical control enclosure using a DIN rail installation arrangement.
DIN rail mounting helps keep relay assemblies organised and accessible, particularly where multiple control components are installed together.
The plug-in arrangement supports convenient relay replacement because the permanent external wiring remains connected to the socket.
Before removing or inserting a relay, the circuit must be safely isolated. The replacement relay must match the required pin configuration, coil supply and contact characteristics.
Typical Applications
- Industrial automation control panels.
- Machinery electrical control circuits.
- Auxiliary relay switching assemblies.
- Manufacturing equipment.
- Production line control systems.
- Electrical distribution cabinets.
- Building automation systems.
- Conveyor control equipment.
- Packaging machinery.
- Industrial signalling circuits.
- Modular relay installations.
- Electrical maintenance and relay replacement applications.
- Control panels using compatible Finder plug-in relays.
Selecting a Compatible Relay
When choosing a relay for the Finder 94.72.0SMA, confirm the complete relay part number against Finder's socket compatibility information.
The most important selection considerations include the relay's pin layout, coil voltage, contact configuration, rated current, rated voltage and electrical load category.
Relays with a similar external appearance may have different terminal arrangements and are not necessarily interchangeable.
The maximum permissible load of the completed relay assembly must not exceed the ratings of either the socket or the fitted relay.

Frequently Asked Questions
What is the Finder 94.72.0SMA?
The Finder 94.72.0SMA is an industrial plug-in relay socket with screw terminals, DIN rail mounting and a metal retaining clip.
Is the Finder 94.72.0SMA a complete relay?
No. It is a relay socket. A compatible plug-in relay must be installed separately to provide the switching function.
Does the Finder 94.72.0SMA use screw terminals?
Yes. The socket features screw terminal connections for the external electrical wiring.
Can the Finder 94.72.0SMA be mounted on a DIN rail?
Yes. It is designed for DIN rail installation inside a suitable electrical enclosure.
Does the Finder 94.72.0SMA include a retaining clip?
Yes. The SMA version incorporates a metal retaining clip to help secure the compatible relay.
What does the metal retaining clip do?
The clip helps hold the installed relay securely in position and can be released when the relay requires replacement.
Does the Finder 94.72.0SMA have its own switching contacts?
No. The switching contacts are part of the compatible relay installed in the socket.
Does the Finder 94.72.0SMA have a coil voltage?
The socket itself does not contain an operating coil. The required coil voltage is determined by the compatible relay selected for the installation.
