Autonics Corporation offers a wide range of cylindrical photoelectric sensors. The BR series is available with M18 cylindrical dimension. It comes in two types, diffuse reflectives type & through-beam type. Diffuse type is available with 100 & 400 mm sensing ranges. Through beam type is available with 20 metre & 4 metre sensing ranges. Sensitivity adjustment is possible for the diffuse type with a potentionmeter. These work with 12-24 V DC. The infrared sensors have less discrimination between white & black targets compared with the visible light. Light-on/dark-on is selectable using the control wore for diffuse type. For through-beam series, the light-on/dark-on models are separately available. The sensors are shortcircuit and reverse polarity protected available with IP66 protection. BR4M series of is available with a special lens having the resistance to environment. All the sensors in this series are available with 2 m cable. Both plastic & metal body versions are available in diffuse type; and through beam type is available only in metal housing. Br200-DDTN is a new model with narrow beam. Typical applications are in packaging machines for detection of presence/absence of cartons, detection of targets passing in the narrow place, detecting the fallen bottles in a conveyor, detecting the label in a transparent bottle, detecting the automobiles for auto doors, detection of broken drill in a drilling machine, detection of tile in a conveyor, etc. The BR series is CE approved.
