This category brings together the brand’s Industrial Ethernet, serial and fieldbus connectivity for panels, machines and on-site wiring. Weidmüller structures the range into copper and fiber cables, board and field connectors, patch leads, managed and unmanaged switches, DIN-rail media converters, and I/O or serial gateways. Buyers are panel shops, OEMs, utilities and MRO teams building reliable links between PLCs, HMIs, drives, sensors and SCADA—where IP rating, EMC performance and serviceability matter more than office-grade speed tests.

weidmuller network cabling families and grades

Cabling follows clear tiers: Cat5e for legacy lines and drives, Cat6 for standard PLC-to-HMI runs, Cat6A for PoE and camera backbones, plus multimode or single-mode fiber when distances or EMC demand it. Stock codes typically split by jacket (PVC, LSZH, PUR), shielding (U/UTP, F/UTP, S/FTP), and color for plant standards. Most distributors carry 100 m and 305 m reels, plus pre-terminated patch leads from 0.3 m to 20 m for cabinet runs. For moving axes, pick PUR high-flex types with chain approvals; for outdoor trays, UV-stable jackets keep prints legible over time.

For cabinets, RJ45 field-assembly plugs with tool-less IDC save minutes per drop; panel-feedthroughs handle keystone or compact footprints. On machines, M12 D-coded handles 100 Mbit zones and M12 X-coded supports Gigabit and higher, with IP67 bodies in nickel-plated brass or robust polymer. Straight and right-angle forms fit tight doors; color rings help maintenance identify VLANs or network tiers. Popular variants ship as pre-made patch cables—RJ45-RJ45 for panels, M12-RJ45 for device drops, and M12-M12 for sensor clusters.

Where sites standardize their infrastructure, you’ll find DIN-rail switch families (unmanaged for islands, managed for VLANs, RSTP and diagnostics), media converters for copper-to-fiber handoffs, and PoE injectors to power cameras or access points from the control bay. Compact housings keep the 45 mm pitch; removable terminals and front status LEDs make service quick. Fiber accessories include LC/SC patch panels, splice cassettes and pigtails so enclosure work stays clean and labeled.

Applications and compatibility

Typical applications span packaging lines, bottling halls, wastewater plants, HVAC rooftops, lifts and crane controls. Everything lands on TS35 rails next to power supplies and terminal blocks. For basket building, pair with Weidmüller DIN rails, 24 V power supplies, PE/earth terminals, cable markers, cable glands and wire ducts—so routing from entry to port to terminal is consistent and documented.

weidmuller data transmission modules for fieldbus and serial

Beyond Ethernet, Weidmüller covers RS-232/485, CAN, Profibus and Modbus with surge-friendly interface blocks, repeaters and serial-to-Ethernet gateways. DIN-rail media converters add fiber resilience to noisy runs; protocol-aware isolators protect PLC ports. Many modules include pluggable terminals and relay outputs for alarms—handy for pulling diagnostics into SCADA without extra I/O cards. Fast movers are RS-485 repeaters for long conveyor lines and serial device servers that bring legacy drives onto the plant LAN.

weidmuller communication accessories to complete the bill

Finish the job with DIN-rail patch panels, keystone frames, cable strain reliefs, cord grips, blind plugs, ID rings and test cords. Add panel earthing kits and shield clamps so braided screens terminate 360° right at entry. For fiber, order the splice cassette, heat-shrink protectors and a small tray of LC/SC couplers with dust caps. These are the small parts that prevent site delays when commissioning windows are tight.

Integration with other Weidmüller products

RJ45 panels and switches share the same device pitch as relays and PSUs, so your layout stays modular. M12 cable assemblies route neatly through the brand’s EMC cable glands; shield continuity carries from gland to clamp to PE terminal. Marker carriers match terminal block systems, which keeps port labeling consistent from patch panel to I/O slice. Power PoE loads from Weidmüller 24 V supplies via injectors sized for your watt budget.

Selection criteria for B2B clients

Environment and movement. Static panels accept PVC or LSZH; moving axes need PUR high-flex to avoid jacket cracking.
EMC and distance. In heavy drives areas or long runs, step to S/FTP copper or go fiber to eliminate noise headaches.
Connector format. Use RJ45 for cabinets; M12 D-coded for 100 Mbit devices; M12 X-coded where Gigabit or IP67 is required.
PoE and power. Confirm PoE class against injector/switch budgets; leave 20% headroom for temperature derating.
Service model. Tool-less field plugs and pre-made leads speed retrofit jobs; managed switches pay back with diagnostics on larger plants.
Bill completeness. Add glands, shield clamps, labels, and spare patch cords—these low-cost items stop re-visits.
