Why Choose the Finder 94.03.0SMA Relay Socket?
The Finder 94.03.0SMA is an 11-pin, three-pole changeover (3 CO) relay socket designed for compatible Finder industrial relays. Part of the established Finder 94 Series, this socket provides a secure, convenient connection between a removable electromechanical relay and fixed electrical control wiring.
Featuring screw terminals and a 10 A, 250 V socket rating, the Finder 94.03.0SMA supports dependable relay connections in industrial automation, machinery control and electrical panel installations. Its DIN rail mounting arrangement helps simplify installation and maintain organised wiring inside electrical cabinets.
The 94.03.0SMA is associated with Finder's three-pole relay socket configuration, with compatibility listings including the Finder 85.03 relay family. The related 94.03 socket family also includes variants for Finder 55.33 relays, so the exact relay and socket combination should be checked before installation.

Reliable Three-Pole Relay Connections for Industrial Control Systems
The Finder 94.03.0SMA provides the electrical interface between a compatible removable relay and permanently installed control wiring. Its 11-position configuration accommodates the connections associated with a three-pole changeover relay, allowing separate control and switching circuits to be incorporated into industrial electrical equipment.
The screw terminal arrangement enables installers to terminate conductors securely, while the DIN rail mounting format supports organised control panel construction. Using a dedicated relay socket also makes servicing more convenient because the relay can be removed without disconnecting the fixed socket wiring.
For dependable operation, the installed relay must match the socket's pin arrangement and mechanical configuration. The selected relay's coil voltage, contact ratings and switching characteristics must also be appropriate for the application. The complete assembly must remain within the lowest applicable electrical rating of its components.
Typical Applications
- Industrial automation and machinery control panels.
- Three-pole changeover relay switching circuits.
- PLC-controlled relay interface assemblies.
- Electrical control and signalling equipment.
- Industrial process control systems.
- Manufacturing and production machinery.
- Conveyor and material handling systems.
- Building automation and HVAC control panels.
- Control circuit interlocking and auxiliary switching.
- OEM electrical equipment and panel manufacturing.
- Industrial maintenance and relay socket replacement.

Frequently Asked Questions
What is the Finder 94.03.0SMA used for?
The Finder 94.03.0SMA is an 11-pin relay socket used to connect compatible three-pole electromechanical relays to fixed wiring in industrial automation, machinery control and electrical switching applications.
Is the Finder 94.03.0SMA a complete relay?
No. The Finder 94.03.0SMA is a relay socket, not a complete switching relay. A compatible relay must be installed to provide the electrical switching function.
How many pins does the Finder 94.03.0SMA have?
The socket has 11 connection positions, suitable for the coil and three changeover contact circuits of a compatible relay.
What contact configuration does the Finder 94.03.0SMA support?
It supports compatible three-pole changeover (3 CO or 3PDT) relay configurations, providing connections for three independent changeover contacts.
What are the electrical ratings of the Finder 94.03.0SMA?
The socket has a 10 A rated current and a 250 V rated voltage. The complete assembly must also comply with the installed relay's ratings.
Which relays are compatible with the Finder 94.03.0SMA?
Product listings identify the Finder 85.03 relay family for the 94.03.0SMA variant. Related 94.03 socket variants are also used with Finder 55.33 relays. Confirm the exact relay part number and pin configuration before installation.
Does the Finder 94.03.0SMA use screw terminals?
Yes. The socket uses screw terminal connections for terminating control and switching circuit conductors.
Can the Finder 94.03.0SMA be mounted on a DIN rail?
Yes. The Finder 94.03.0SMA is designed for DIN rail mounting, making it suitable for modular electrical control cabinet installations.
