Circular Connectors

The right connection for your application outside the cabinet: high IP rated circular connectors for sensors and actuators

Circular Connectors

Comprehensive circular connectivity solutions

In an increasingly digital environment, the reliable transmission of power, signals and data requires the rapid availability of standardised cabling solutions and the development of individual special cables. Irrespective of whether you require signal cables for sensor lines or data cables for Ethernet lines with different mating profiles – Weidmüller offers the right solution for every field of application.

Also our extensive range of IP-protected circular connectors in sizes M8, M12, M16, M23, and 7/8" ensures the reliable cabling of your system. During development, we always concentrate on efficient and cost-effective assembly and installation concepts. In this way, we offer sophisticated products and set global standards in terms of functionality and quality. Our field-attachable circular connectors are available with a variety of connection techniques, including screw, tension spring, IDC, PUSH IN, crimp or solder connection technologies.

IP68 circular connector – Screwable and click-in M20 plugs Product innovation

Connect cables and applications safely and quickly

Our IP68 circular connectors enable secure connections for LEDs and control cabinet connections in external applications. The connectors ensure a tight connection between two cables or between the cable and the application. The great advantage of our new circular connectors: connections can be made particularly quickly and, especially, securely. The plugs are easy to use, have a haptic response and can be used universally in many application environments.

Perfect complements for industrial connectors

Single Pair Ethernet

Industrial plants are becoming increasingly digitalized, which means that conventional Ethernet cabling for sensors and control units is no longer sufficient. In developing new industry standards, Weidmüller relies on the innovative Single Pair Ethernet technology. Single Pair Ethernet enables the end-to-end connection of a large number of devices in the Industrial IoT, from the sensor to the cloud.

Fieldbus Distributors

Connecting smart field devices to your fieldbus segments. Our FBCon fieldbus distributors have EMC cable glands with high screening attenuation and are available in aluminum or stainless-steel variants as well as ATEX variants for hazardous areas. FBCon with integrated current limitation protect bus communication in the event of short circuits on the field device.

Distribution boxes

Modern automation solutions are becoming increasingly decentralised. As a result, you need components that can be easily integrated into the common automation systems and are more efficient to connect than time-consuming individual wiring. Flexible distribution boxes enable reliable, decentralised signal and power transmission up to protection class IP67 - wherever functions are required.

Cord sets, patch cables and cables

Whether standardised or individual: our demand-oriented assembly services support you in handling even the most complex of cabling tasks. Choose from our extensive range of prefabricated cables, or use our online configurator to create individual signal signal cables for sensors or data cables for Ethernet.

Signal wiring

Tailored application products with all benefits required for structured wiring of initiator and actor signals Our application-specific initiator/actuator terminalblocks (AIO) are specially designed for the signal wiring requirements posed byautomation now and into the future. You can benefit from tailored, really compactsolutions for the structured wiring of initiator and actuator signals with the inputand output modules of a programmable logic controller (PLC).
