Miti-Eye

MITY-EYE General Purpose Photoelectric Sensor

MITY•EYE® Miniature Photoelectric Sensors provide the same features and benefits of large, expensive sensors... at an affordable price. Interchangeable solid "optical grade" high impact lenses available for polarized, retroreflective, proximity, fiber-optic, or convergent sensing applications.

Designed for trouble-free operation, many features have been incorporated into the MITY•EYE® to prevent mechanical or electrical damage and to provide trouble-free operation. The sensitivity pot is protected with a clutch to prevent damage from over-travel. The entire sensor is epoxy-encapsulated to ensure mechanical strength. The case itself is rugged and watertight.

AC models prevent electrical mishaps with an optically isolated AC solid state switch is protected by an MOV (Metal Oxide Varistor). In addition, the AC switch turns on synchronously at near zero volts which helps to prevent electrical line noise generated by hard relay contacts or inductive loads.

OUTPUT INDICATOR
Red LED illuminates when outputs are ON.

GASKET
Sealed to provide moisture protection.

POTENTIOMETER ADJUSTMENT
Protected to prevent over-travel.

HINDGED DOOR
To protect adjustments.

INTERCHANGEABLE OPTICAL BLOCK
See Sensing Ranges for best choice.

LIGHT/DARK SWITCH
Toggle between Light On and Dark On.

LIGHT SOURCE SELECTION

Infrared Light Source
Invisible light – recommended in opaque object sensing applications. Infrared LED light source provides long-range sensing in either Beam Make or Beam Break modes. Infrared light maximizes the sensor’s ability to penetrate contamination found in harsh environments.

High Intensity Red
Recommended for long-range proximity sensing and for use with plastic fiberoptic light guides.

 

Red (Visible) Light Source
Visible red LED light source recommended for sensing transparent/translucent objects. Outperforms infrared light in many moderate to low contrast applications. Also recommended for use with plastic fiberoptic light guides.
