Reliable PCB Relay Connections for Electronic Control Equipment
The Finder 95.13.20SMA provides a practical connection between a compatible Finder 40.31 electromechanical relay and the copper tracks of a printed circuit board. Rather than soldering the relay directly into the PCB, the socket is installed as the permanent board-mounted component, allowing the relay to be inserted and removed separately.
This arrangement can simplify maintenance and component replacement in industrial electronic equipment. If the relay requires inspection or replacement, it can be removed from the socket without applying soldering heat to the circuit board or disturbing the surrounding PCB connections.
The socket features a five-position connection arrangement suitable for the specified relay's coil and switching contact terminals. Its through-hole PC pins are designed for soldered installation into a circuit board with the correct footprint and hole arrangement.
The 3.5 mm relay pin spacing is an important compatibility characteristic. Engineers should confirm the PCB footprint, relay pin arrangement and connection diagram before specifying the socket for a new board design or replacing an existing component.
The Finder 95.13.20SMA has a 12 A rated current and 250 V rated voltage. However, the permissible current in a completed assembly also depends on the installed relay, PCB copper track dimensions, solder connections, temperature conditions and electrical load characteristics.
The SMA designation identifies the version supplied with a metal retaining clip. For the Finder 95.13.20SMA, the included clip is the Finder 095.51.
The metal retaining clip helps keep the compatible relay correctly seated in its socket during normal equipment operation. This is particularly useful in machinery and industrial electronics where vibration, movement or repeated servicing could otherwise affect a removable component.
The retaining arrangement also supports convenient maintenance. When the relay needs to be replaced, the clip can be released and the relay removed from the socket, leaving the soldered PCB connections undisturbed.
Finder also identifies the 095.52 plastic retaining clip as an accessory option for compatible 95 Series PCB sockets. The correct retaining accessory should be selected according to the socket and relay combination.
Designed for Through-Hole PCB Installation
Unlike DIN rail relay sockets, the Finder 95.13.20SMA is intended for through-hole printed circuit board mounting. Its metal connection pins are inserted into the appropriate PCB holes and soldered to the circuit board.
This construction is suited to electronic control modules, machinery control boards and OEM equipment where the relay forms part of a larger electronic assembly. The socket enables the switching component to remain removable while the PCB provides the permanent electrical interconnections.
The black housing distinguishes the 95.13.20 socket from the corresponding blue 95.13.2 variant. Both belong to the Finder 95 Series PCB socket family, but the correct colour, mounting footprint and retaining clip option should be confirmed when ordering replacement components.
The socket's IP20 protection category means it should be installed within equipment that provides the necessary protection against accidental contact, moisture and environmental exposure. Appropriate electrical clearances, PCB track spacing and insulation requirements must also be maintained.
With its removable relay arrangement and included retaining clip, the Finder 95.13.20SMA is particularly suitable for equipment designers who value serviceability, component replacement and dependable PCB relay mounting.
