Application and characteristics of the B-1T detector
The B-1T magnetic detector is a basic component of a perimeter protection system and is used to detect the opening of doors and windows. Thanks to its reed switch design, it reacts to the change in position of the magnet relative to the reed switch element, which allows it to precisely detect the violation of the protected leaf.
The B-1T model is designed for surface mounting, fixed only by screwing to the ground. The medium-sized housing with the same dimensions of the magnet and reed switch parts allows aesthetic installation on various types of door and window woodwork. The manufacturer offers the detector in two color versions: white and brown, which makes it easy to match the color of the substrate.
Operating conditions and performance parameters
The B-1T detector is designed to operate in a wide range of temperatures, which allows it to be used in typical indoor conditions, in accordance with the environmental class defined by the EN50130-5 standard. The electrical parameters of the reed switch, such as the maximum switching voltage, maximum current and load power, ensure correct cooperation with control panels and other elements of the intrusion detection system.
The proper closing and opening distances of the reed switch contacts define the distance between the magnet part and the reed switch part at which the circuit is shorted or opened. The low weight of the device and the compact dimensions of both elements facilitate installation and do not mechanically burden the structure of the window or door.
