Connection Methods


Inductive sensors can be integrated into systems in various ways. The various versions of sensors with fixed cables with or without plugs or with connector plugs are available as standard in various designs.


Terminal Compartment

Sensors of this type have a designated area in the sensor housing for electrically interconnecting the sensor to the plant. The terminal compartment allows users to freely select the connection cable. This is of particular benefit in applications involving UV resistance or resistance to chemical agents. In addition, users are not tied to fixed cable lengths, and the terminal compartment offers increased tamper protection compared to versions with connectors.

Pepperl+Fuchs inductive sensors with terminal compartments may contain the type designation "KK" in the second position of the type code.

Fixed Cable with or without Connector

Sensors of this type have a fixed cable that can be preassembled or a fixed cable with a typical connector for industrial automation. Sensors with fixed cable are affordable options, since they do not require an additional single-ended female cordset and keep the number of connection points to a minimum. Connection to special connectors is possible depending on the application requirement (e.g., automotive industry).

Inductive sensors of this type do not have a special type designation at the end of the type code.

Connectors for Data Transfer

Inductive sensors are available with a standard selection of industrial automation connectors, including M8 and M12, 1/2 inch and 7/8 inch. When replacing the sensor, the cabling does not need to be replaced completely. This prevents error-prone new connections in the terminal compartment. Standardized single-ended female cordsets are available in the Pepperl+Fuchs accessories range.

Inductive sensors with these connection options have one of the following type designations at the end of the type code: V1, V3, V5, V13, V16, V18.

Other Connections

In addition to other versions, e.g., FASTON® connectors or sensors with solder connections are available.

1 Both cores should be the same color.
2 The pinout numbers correspond to the numbering of the pins on the connector plugs.  This does not apply to proximity sensors for AC and those with three-pin 8 mm plugs.

Switches without protective insulation require a protective conductor terminal for voltages above 50 V AC and 120 V DC.
