Product Description
The KW715 series reflective assembly integrates a GaAs LED and a Photologic sensor within an IR transmissive housing. Designed to detect paper at 0.5" (12.7 mm), these sensors offer a wide operating distance range, capable of detecting reflective objects at varying distances dependent on the material's reflectivity. They serve as replacements for conventional mechanical limit switches where longevity and reliability are paramount. The sensors feature a snap-mount design for 20-gauge material (0.036" thick) with a 0.315" x 0.472" (8.0 mm x 12.0 mm) rectangular opening. The panel-mount plastic housing shields stray light and terminates with 18" (457 mm) UL-approved 26 AWG wire leads. The internal current-limited LED offers convenience. Output options include Totem-Pole or OC Open-Collector, with inverted output configurations available for both.
