Transmitter for wireless buttons without head, Plastic ZBRT1

Wireless transmitter for buttons – reliable communication in control systems

This transmitter, a component of the Schneider Electric Harmony XB5R and XB4R series, is a key element of wireless control systems. Designed to work with buttons, it enables remote signal transmission, increasing installation flexibility and convenience. It is ideal for both industrial applications and commercial buildings or smart homes.

Functionality and application

The device operates in the 2400 MHz frequency band, using FM (VHF) modulation for reliable data transmission. A range of up to 300 meters ensures comfortable operation even in large spaces. The transmitter is designed for built-in mounting, allowing for discreet integration with existing infrastructure. Thanks to the use of a radio encoding device, the transmission is protected against interference and unauthorized access. Its main task is to send a single radio frame each time the button is pressed – a simple but effective solution for many applications.

Construction features and operating parameters

The housing made of plastic provides durability and resistance to mechanical damage. The IP65 protection rating guarantees tightness against dust and water jets, allowing operation in harsh environmental conditions. The device is powered in an "Other" manner, suggesting the use of a batteryless solution (along with compatible buttons). The weight of only 25g makes installation easier and minimizes structural load. It should be noted that there is no keyboard protective cover or a variable code system (carousel), which affects the scope of its applications – ideal where simplicity and reliability are a priority.
