Miniature Photoelectric Sensors - Tri-Tronics Co Inc



Tampa, Florida: TRI-TRONICS COMPANY, INC. has introduced a full line of very economical, miniature photoelectric sensors designed to perform most sensing tasks from even the tightest locations. The new rugged MINI-EYE™ sensors are waterproof and enclosed in high-impact plastic housings for use in hostile environments. They are also immune to indirect ambient light and strobes. These versatile sensors are available in thru-beam, retroreflective and proximity models for performing object detection such as web break detection, counting, inspection, orientation...and much more!

MINI-EYE sensors offer a selection of either infrared (IR) or red LED light sources, and NPN or PNP output transistors. All models are available with quick disconnect or potted cables, and they can be operated in either the Light "On" or Dark "On" modes.


SUPPLY VOLTAGE • 10 to 30 VDC • Polarity Protected CURRENT REQUIREMENTS • 30mA (exclusive of load) OUTPUT TRANSISTORS (CURRENT LIMITED) • NPN: Sink up to 100mA • PNP: Source up to 100mA • All outputs are continuously short circuit protected RESPONSE TIME • Light State response = 600?s (1,100?s, Thru-Beam) • Dark State response = 600?s (1,100?s, Thru-Beam) LED LIGHT SOURCE • Red = 633 NM • Infrared = 850 NM • Pulse Modulated EXCESS GAIN ADJUSTMENT • Sensitivity controlled by a screwdriver adjustment to prevent tampering LIGHT/DARK “ON” OPERATION • Light “ON” achieved by connecting white wire to negative lead • Dark “ON” achieved by connecting white wire to positive lead RANGE • Dependent on model, see Brochure HYSTERESIS • Approximately 20% of signal LIGHT IMMUNITY • Responds to sensor’s pulse-modulated light source, resulting in high immunity to most ambient light, including high intensity strobes DIAGNOSTIC INDICATORS • Red LED = Output Status • Green LED = Power “ON” AMBIENT TEMPERATURE • -40° to 70°C (-40° to 158° F) RUGGED CONSTRUCTION • Chemical resistant, high-impact polycarbonate housing • Waterproof ratings: NEMA 4X, IP66
