Perfect complements for industrial connectors

Single Pair Ethernet

Industrial plants are becoming increasingly digitalized, which means that conventional Ethernet cables for sensors and control units are no longer sufficient. In developing new industry standards, Weidmüller relies on 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 decentralized. 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, decentralized signal and power transmission up to protection class IP67 - wherever functions are required.

Cord sets, patch cables, and cables

Whether standardized 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 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 terminal blocks (AIO) are specially designed for the signal wiring requirements posed by automation – now and into the future. You benefit from tailored, compact solutions for the structured wiring of initiator and actuator signals with the input and output modules of a programmable logic controller (PLC).
