BeamBar4T

The Beambar4T is a multiple infrared Beam device designed specifically for timing applications. With a response time of 1mS it is ideal for applications which require accurate time measurement. Four time multiplexed beams are arranged with a separation of 75mm, an output being generated if two adjacent beams are broken. The Beambar4T is housed in a white ABS box 300mm long x 44mm wide x 254mm deep, allowing a very compact installation. Additional fixings are provided which permit a wide range of installation options. Installation is facilitated by the provision of several features such as test LEDs for each beam and automatic gain reduction during installation.
