Abstract
Disclosed herein is an exemplary photoelectric sensor having an emitting portion for emitting light toward a target and a receiving portion for receiving, through a receive lens, reflected light that is at least some of the emitted light that is reflected by the target. The sensor further includes a refraction block having a block first surface and a block second surface wherein the reflected light received from the receive lens is refracted by at least one of the block first surface and the block second surface as it passes through the refraction block. The sensor also includes a photodetector for receiving the reflected light refracted by the refraction block and provides a detection signal indicative of the reflected light received.
