Optical sensors target rugged applications
The OPB715 series of digital output reflective optical sensors from TT Electronics-Optek are available at TTI.
The matched sensor pair is designed with a snap in mounting feature for ease of manufacturing.
This sensor is targeted for industrial and ruggedised applications including, robotics, machine and process automation and touchless sensing.
The OPB715Z series reflective assembly consists of a GaALAs LED and a Photologic sensor enclosed in an IR transmissive housing.
The sensor is characterised to detect objects at 0.5-in. (12.7 mm), and it has a wide operating distance range and is capable of detecting reflective objects at greater distances.
The reflective distance depends on the reflectance materials.
These devices are designed to replace conventional mechanical limit switches where long life and reliability are critical.
The switches are designed to easily snap mount into a 0.036-in. (0.914 mm) 20 gauge thick material with a rectangular opening of 0.315-in. x 0.472-in. (8.0 mm x 12.0 mm).
The sensor’s panel-mount plastic housing shields stray light and is terminated with 18-in. (457 mm) UL approved 26 AWG wire leads.
The LED is current limited internally for design convenience.
Its output can be specified by part number sequence as Totem-Pole, Open-Collector, Inverter Totem-Pole and Inverter Open-Collector.
