UNIVERSAL INPUT VOLTAGE
24-130 volt AC/DC input range. Input surge suppressed and fault protected.
OUTPUTS & STATUS INDICATORS
5 amp relay or 1 amp triac outputs. Beam status and output indicators work in conjunction with timers.
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.
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.

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.
