Abstract
The present invention provides an automatic faucet with a movable cam assembly for mounting the senor and sensor window inside of the faucet body. The cam has an obliquely angled surface and can be moved up against a spring to provide space for assembling the sensor inside the faucet. Once the sensor is properly positioned, the spring drives the wedge-like cam back down to apply a holding force against the sensor and the window. Back pressure against the sensor or window can be absorbed to some extend by the spring to reduce the chance of damaging the window and/or sensor from impact.
