Reliable 8-Pin Connections for Finder 56.32 Relays

The Finder 96.72SMA provides the electrical and mechanical interface between a Finder 56.32 electromechanical relay and the permanent wiring of an industrial control system. The socket's eight connection positions accommodate the relay's coil terminals and its two changeover contact circuits.

The associated Finder 56.32 relay uses a DPDT (double-pole, double-throw) contact configuration, also described as 2 CO. This allows two separate circuits to be switched using one relay, making the arrangement suitable for auxiliary control, equipment signalling and other industrial switching applications.

The socket itself does not contain the switching contacts or relay coil. These functions are provided by the separately installed relay. Consequently, the coil operating voltage, contact characteristics and switching performance depend on the exact Finder 56.32 relay selected.

Its 12 A socket rating and 250 V rated voltage must be considered alongside the ratings of the installed relay, conductor sizes and connected load. The maximum permissible load of the completed assembly is limited by its lowest-rated component.

This modular approach is especially valuable for maintenance. If a relay requires replacement, it can be removed from the socket without disconnecting the permanent control panel wiring, reducing unnecessary disturbance to the installation.

Secure Screw Terminals and Flexible DIN Rail Mounting

The Finder 96.72SMA uses plate-clamp screw terminals to provide dependable electrical connections for suitable solid and stranded conductors. This terminal construction is designed for industrial installations where secure conductor retention and consistent wiring practices are essential.

Finder specifies a 0.8 Nm screw tightening torque and 10 mm conductor stripping length for this socket. Correct conductor preparation and tightening help maintain reliable electrical contact and reduce the risk of loose terminations.

The socket accommodates suitable solid conductors up to 4 mm² and stranded conductors up to 4 mm² in single-conductor arrangements. Permitted two-conductor arrangements depend on conductor type and must follow Finder's terminal specifications.

For installation, the socket can be mounted on a standard 35 mm DIN rail according to EN 60715 or secured using the appropriate panel mounting arrangement. This flexibility allows engineers to use the same socket type across different electrical cabinet and machinery designs.

The socket has an IP20 protection category and should be installed inside an electrical enclosure that provides the required protection against moisture, contamination and accidental contact with live components.

Included Finder 094.71 Metal Retaining Clip

The SMA suffix identifies the version supplied with a metal retaining clip. For the Finder 96.72SMA, this is the Finder 094.71 retaining clip.

The clip helps hold the compatible Finder 56.32 relay securely in position, making it particularly useful in industrial equipment where vibration, mechanical movement or repeated servicing may occur.

When maintenance is required, the retaining clip can be released to allow the relay to be removed from its socket. This provides a convenient replacement arrangement without requiring the permanent socket wiring to be disconnected.

The metal clip is included with the 96.72SMA socket, but the Finder 56.32 relay itself is supplied separately.

Optional Finder 99.01 Indication and Suppression Modules

The Finder 96.72 socket supports selected Finder 99.01 coil indication and EMC suppression modules. These accessories provide additional functionality for compatible relay installations.

Depending on the module selected, available functions include LED coil indication, diode suppression and other voltage-dependent suppression arrangements. These can help provide visual confirmation of the control signal and manage electrical transients associated with relay coil operation.

The correct module must be selected according to the relay coil voltage, AC or DC supply type, polarity requirements and electrical characteristics of the control circuit. Not every 99.01 module is suitable for every relay coil.

The standard Finder 96.72SMA does not include a 99.01 module. Indication and suppression modules are separate accessories unless specifically stated as part of a supplied assembly.
