The LT and LR series from Telco Sensors are a range of amplified photoelectric sensors. These photoelectric sensors are connected to PA, PMA or PAB amplifiers. Photoelectric sensors with a separate amplifier are available in a variety of sizes with fixed cable or a connector with a maximum range of up to 70 meters. The use of separate amplifiers allows the user to make use of a compact sensor but still have excess power to use in applications with a lot of dirt buildup. In addition, the amplifier provides extra flexibility with the inifinite sensitivity adjustability and on/off delay. The amplifiers are available in 24 Vac/Vdc or 230 Vac.
LT/LR photoelectric sensors from Telco Sensors
The LT (transmitter) and LR (receiver) photoelectric sensors are connected to a PA, PMA and PAB amplifiers. The LT/LR photoelectric sensors are available in various sizes and with a connector or fixed cable. The complete series consists of the 100, 110 and 120 series with the 18, 40 and 70 ranges respectively.
Photocell amplifiers from Telco Sensors
The Telco Sensors (multiplex) photoelectric amplifiers from the PA(B) series are amplifiers that are used on the LT/LR photoelectric sensors from the 100, 110 and 120 series. The PA 11 series photoelectric amplifiers from Telco Sensors are specific to the LT/LR 100 and 110 series. The PAB series amplifiers can be used with the LT/LR photoelectric sensors from the 100, 110 and 120 series. The PA 11 series can be mounted on an 11-pole DIN rail socket and is available in 24 Vdc/Vac and 230 Vac. The PAB series amplifiers are available in 1, 2 or 3 channels and can be multiplexed via BUS rail to prevent mutual interference.
