Photologic Reflective Object Sensor KW715, KW716, KW717, KW718
The KW715 series reflective assembly features a GaAIAs LED and a Photologic sensor within an IR transmissive housing. Designed to replace mechanical limit switches where long life and reliability are critical, these sensors are characterized to detect paper at 0.5" (12.7 mm) and offer a wide operating distance range capable of detecting reflective objects at varying distances, dependent on the reflectance material. The sensors are designed for easy snap-mounting into 0.036" (0.914 mm) 20-gauge thick material with a rectangular opening of 0.315" x 0.472" (8.0 mm x 12.0 mm). The panel-mount plastic housing shields stray light and is terminated with 18" (457 mm) UL approved 26 AWG wire leads. The LED is internally current-limited for convenience. Output options include Totem-Pole or open-collector, with inverted output options available.
