Switches International has been marketing the successful range of TJC sensors from Europe for the past five years with increasing success. This range of infrared sensors has a wide range of applications such as safety on machines, item sensing/counting on assembly lines, etc.
These compact sensors are available in a wide variety of options, including proximity sensors, emitter/receiver, and through-beam combinations. By powering these units with an external microprocessor-based amplifier, minimal space is required when mounting the infrared sensors. Various housing and shape options are also available, and sensing ranges of up to 30 m are achievable.
The amplifiers are offered with supply voltages ranging from 12 V (AC/DC) up to 240 V a.c. and feature either relay or solid state/transistor outputs. Options include dual, or four-channel isolated outputs for multiple sensors. Optimal sensing is ensured by the automatic sensitivity adjustment feature incorporated in the amplifier. This function means that even in dusty conditions the sensor operation is kept at optimal sensing power, and also assists when moderate misalignment has occurred.
