Wire & Cable Connectors UK: WAGO, RJ45, BNC Baluns

Connectors for CCTV and low-voltage installs

This range covers the small hardware that makes cabling reliable: lever-style wire connectors (SPL-3, WAGO 221 series, 108 push-wire blocks), power connectors and splitters for 12V DC runs, RJ45/CAT5e/CAT6 couplers for extending network cable, and video baluns for running BNC-based CVI/TVI/AHD/CVBS signals over twisted-pair cable.

How to choose

• Signal vs power vs data — decide first whether you're joining mains/DC power (lever connectors, WAGO blocks, 12V plug/socket adapters), extending a network run (RJ45 couplers), or converting analogue video (BNC-to-RJ45 baluns).
• Port count — lever connectors range from 2-way splitters up to 8-port inline blocks; match port count to the number of branches on site.
• Current and voltage rating — WAGO 221-2411 and 221-2401 are rated 32A; check ratings against the load before use on power distribution.
• Camera compatibility — the 8MP CCTV balun supports CVI/TVI/AHD/CVBS; the 4CH balun handles up to 1080p HD, useful where several analogue cameras share one run.
• Termination method — crimp IDC connectors suit telephone/CCTV jelly-filled cable, while lever and push-wire types need no tools for a quick reconnection.
