Sensors target objects, ignore background
Pepperl+Fuchs, a Twinsburg, Ohio-based manufacturer of sensors, has added background suppression to its GLV18 photoelectric line.
A mechanically adjustable sensing range cut-off detects all colours at distances up to 120 mm. Black and white test objects are seen to within 6% of the same distance.
The sensors come in a M18 threaded cylindrical housing that is up to 50% shorter and power consumption is reduced by up to 50% more than other M18 cylindrical photoelectric sensors.
Background suppression allows the sensors to ignore objects that appear beyond the desired target. This eliminates the need for a reflector, or frequent readjustments for sensitivity.
Every GLV18 sensor includes a flush-mount bracket for installation on a conveyor. Ball-and-swivel and half-clamp mounting brackets are also available.
