U.S. EYE® Photoelectric Sensors were designed and built by TRI-TRONICS® to answer the demand for economical, high-performance AC sensors. They are available with a unique Contrast Indicator for difficult sensing tasks and without the Contrast Indicator for simple tasks at an even lower cost.

Function modes available:

ON/OFF – output relay switches for duration of input.

Type T1, delay timer – offers two options using light/dark switch:

a) “ON” delay for product jam or backup detection.

b) “OFF” delay for product void detection.

Type T2, “one-shot” timer – may be used for short, momentary output pulse or in the “triggerable” mode for “stop motion” detection. (See Timing Sequence Data Charts.)

Contrast Indicator Models

The Contrast Indicator displays a scaled reading of the level of light received by the sensor’s photo detector. The more light received, the higher the reading. The less light received, the lower the reading. Contrast is a comparison of the lightest state reading vs. the darkest state reading. The sensing task of any photoelectric sensor is to resolve the difference between these two light levels and switch the output accordingly. The U.S. EYE® switches its output when the light level passes the midscale reading of “5.” Refer to section 1 for details.

Fiberoptic Models

Flexible fiberoptic light guides are available in sizes small enough to fit into your toughest job sensing sites, with models designed for inaccessible places, detection of extremely small parts, high temperature applications, corrosive environments, or high vibration locations, as well as straight light guides for Beam Break and bifurcated light guides for proximity sensing.
