1. A touchless sensor, comprising:
a motion sensor adapted for detecting an object in a detection zone;
a sensor lens between the motion sensor and the detection zone, the sensor lens having a hand shape;
a housing holding the motion sensor and the sensor lens;
a light source and a light guide within the housing wherein (a) the light guide is annular in shape, (b) the sensor lens is received within the light guide, (c) the sensor lens includes a plurality of locator tabs, and (d) the light guide includes a plurality of locator tab receivers holding said plurality of locator tabs;
a printed circuit assembly held in the housing, the printed circuit assembly including the motion sensor wherein (i) the printed circuit assembly includes a light source that directs light through the light guide around the hand shape of the sensor lens toward the detection zone and (ii) the housing includes an integral modular pin connector that is connected to the printed circuit assembly, whereby the object is detected by the motion sensor through the sensor lens having the hand shape.
