18F Push-In Relay Sockets: Matching and Installation

An 18F push-in relay socket connects field wiring to a removable relay. The socket must match the relay’s terminal pattern and contact arrangement; the family name alone is not enough to establish compatibility.

Choose the correct socket variant.

Jinhong lists the 18F-2Z-C11 and 18F-4Z-C11 as separate push-in socket products. Compare their wiring and dimension drawings with the intended relay before ordering. Do not transfer a terminal number from one pole configuration to another.

Prepare the conductors correctly.

Push-in terminals use a spring connection. Whether a conductor can be inserted directly depends on the terminal design, wire type and use of a ferrule. Follow the socket instructions for conductor cross-section, stripping length, ferrule dimensions and the release tool.

With the circuit isolated, insert each prepared conductor fully and check that it is retained. Ensure that loose strands or exposed copper cannot touch neighbouring terminals.

Check the complete assembly.

Review the ratings of both relay and socket, including the application voltage, current and ambient conditions. Allow access to the release points and space for the relay and any specified retaining clip. Coil accessories, such as an indicator or suppression module, must also match the coil supply.
