Based on the modular M8/M12 circular connector system in accordance with IEC 61076-2-101 / 2-104 / 2-109, robust plug-in solutions for industrial automation can be implemented quickly and reliably. The connectors are suitable for almost all Ethernet and fieldbus specifications and are available in various codings. A-coded circular connectors are used, for example, as sensor connectors or device connectors for digital and analog signal transmission or for power supply. B-coded connector variants are intended for fieldbus interfaces. D- and X-coded circular connectors are designed for Ethernet interfaces.

Erni also covers a wide range of applications with its circular connector portfolio. Customers can choose between different connection technologies (SMT, THR), pole numbers (3-17), codings (A, B, D and X), installation heights (nine and 13 millimetres), sockets, plugs and complete cable assemblies. Gold-plated contacts, robust protection against dust and water as well as shielded versions support use in harsh environments.

There is also a range of accessories such as locking screws, protective caps and O-ring seals. Thanks to the two-part design (plug inserts and locking parts), the locking parts can be integrated into customer-specific injection-moulded and die-cast housings, thus saving costs.

As part of its M8/M12 series, Erni now also offers M12 connectors with twelve and 17 poles in the standard design. With these high-pole M12 variants, the number of required device interfaces can be reduced if bus, I/O, control, service and safety signals are combined in one connector/cable. Typical applications that benefit from the high-pin M12 connectors are complex sensors, cameras, scanners, rotary encoders, I/O boxes, sensor/actuator multipole connections. as
