ABB Busch-tacteo KNX Sensor 2gang TB/U2-CG

Description

Introduction

The ABB Busch-tacteo® KNX sensor TB/U2-CG (Order Code: 2CKA006300A1642) is an individually configurable capacitive glass control element engineered for modern KNX building automation systems. Designed with an ultra-thin glass surface and plastic enclosure, this 2-fold touch sensor serves as a high-end control interface for lighting, heating, blinds, and media scenes across commercial and residential smart buildings. This device is part of our KNX panel range.

Equipped with an integrated KNX bus coupler for direct connection to KNX Twisted Pair (TP) networks, the TB/U2-CG operates reliably within a voltage range of 21–32 V DC supplied directly via the bus line. Featuring integrated proximity and ambient light sensors, as well as programmable multi-color LEDs, the device delivers responsive user interaction and clear orientation lighting while seamlessly fitting into flush-mounted standard device boxes.
