Abstract
A sensor assembly includes a pin housing and a fiber optic sensor. The pin housing receives an end of the fiber optic sensor. The fiber optic sensor has a side-view probe type sensing end which permits right angle sensing. The pin housing includes a side hole that corresponds to a side opening of the sensor allowing light to pass therethrough.
