TRI-TRONICS® designs, manufactures and delivers high quality Photoelectric Sensors that solve problems in industrial packaging, printing, and labeling applications. Photoelectric sensors and fiberoptic light guides designed for a wide variety of industrial automation applications.


The SMARTEYE EZ-Pro is a high performance, digital photoelectric multi-mode sensor that can be set-up by a single push of a button. There is no guess work on the part of the operator.  From that point on, the sensor will automatically maintain a perfect setting, thanks to the dynamic Automatic Contrast Tracking System (ACT). The EZ-PRO™ AUTOSET routine can also be implemented from a momentary remote switch (i.e. push button or touch screen). The EZ-PRO™ is equipped with a Contrast Indicator as well as an Action Alert diagnostic indicator that allows the operator to visually substantiate performance. When the lock feature is enabled (see advanced features), the EZ-PRO™ sensor is tamper-proof.

SmartDot Laser Sensor

The SMARTEYE® SmartDot Laser Sensor is designed for precise, small parts detection at long ranges. The SmartDot Laser Sensor can be easily aligned, repeatedly in order to be used in the inspection and rejection of micro-parts. The SMARTEYE® SmartDot Laser Sensor has an OLED display providing visual confirmation which makes setup a breeze displaying all the necessary information to determine proper setup.


The MARK•EYE® PRO sensor detects printed registration marks on a continuous web running at high-speeds.  It delivers high-resolution by utilizing the broadband characteristics of a white light LED for detecting the greatest variety of color combinations on any color background. The “one-touch” AUTOSET routine can be accomplished by pushing the appropriate button on the sensor or from a remote push-button switch. 

SMARTEYE RetroSmart 

The RETROSMART™ retroreflective sensor is optimized to detect clear/translucent containers and shiny objects from the leading edge to the trailing edge without false signals.  The sensor's narrow, red light beam assures accuracy in detecting the leading edge of any product to trigger the response, such as filling, capping, labeling, and coding.

LABEL-EYE Label Sensor

The LABEL•EYE™ is a photoelectric sensor designed specifically to sense a large variety of adhesive labels. Since the LABEL•EYE™ is an automatic one-touch sensor… not the conventional "teach mode" sensor, set-up is simple. Position the gap between the labels directly under the sensor's sight-guide and push the Autoset button. The sensor does the rest, adjusting itself to the perfect setting. Sensing labels has never been easier.
