Miniature Single Photobeam
E-961-S50TB Single infrared beam, Up to 50ft (15m), Small size
Features:
Small size for a less conspicuous installation
Simple to install
Built-in AGC control to filter out lighting disturbances
Signal strength indicator for easier alignment
LED indicators for power, signal strength, and alarm
Weatherproof for outdoor as well as indoor use (IP65)
Mounting hardware included
The E-961-S50TB is a simple, easy-to-use, and easy-to-install single-beam
infrared motion sensor. The device easily installs almost anywhere to provide an
invisible beam that, when broken, sends a signal to activate a light, beeper, or
other device. This makes the device perfect for use as part of an access control
system, a door or window monitor, a retail store customer alert, or many other
places where the user needs to know that someone has entered a specific room
or building or other protected area. The E-961-S50TB is weather-proof, and
comes with a built-in AGC control circuit that helps to filter out possible
disturbance caused by local lighting conditions.
