HAGER KU9S80YE Cable en Y KNX, negro/azul, 1 conector macho a 2 conectores hembra, 0,8 m

In KNX building automation, branching the bus line often requires a reliable splitter. The HAGER KU9S80YE Y-cable connects one KNX bus plug to two KNX bus sockets, enabling a clean branch without cutting or splicing the main bus cable. The cable is 0.8 m long and uses black and blue data cores, matching standard KNX bus wiring. It is intended for indoor use in KNX installations.

Key specifications

• Connector A: 1x KNX bus plug (male)
• Connector B: 2x KNX bus sockets (female)
• Cable length: 0.8 m
• Cable type: KNX bus cable, 4 cores (2 data, 2 auxiliary power)
• Data wire colours: black, blue
• Rated voltage: 30 V DC (KNX bus)
• Insulation: PVC
• Packaging unit: 1 piece

Why choose it

This Y-cable simplifies bus topology changes. Instead of using junction boxes or additional connectors, you plug it directly into an existing bus line and create two branches. The black and blue colour coding follows KNX conventions, reducing wiring errors during commissioning.

Ideal use cases

• Branching a KNX bus line to feed two separate line segments
• Temporary test setups where a quick tap into the bus is needed
• Retrofit projects where adding a new device requires a bus connection point

Good to know

The cable is designed for indoor use only. It is supplied as a single piece. The green jacket is standard for KNX bus cables, but the actual jacket colour is not specified in the source; the data cores are black and blue.
