Overview
The Tri-Tronics ORC Opti-Eye Sensor 12-24VDC is a miniature DIN rail-mountable photoelectric infrared sensor engineered for tough industrial sensing applications. High performance with minimal footprint, this sensor combines high gain and high-speed response characteristics. The ORC is available with M12 connectors for straightforward integration into modern control systems.
Key Features
- Dual Output Configuration: Both NPN and PNP output transistors—NPN sinks up to 150mA, PNP sources up to 150mA with momentary short circuit protection
- Light/Dark Switch Selectable: Configure for Light-Operate (LT) or Dark-Operate (DK) modes to match application requirements
- LED Indicators: OUTPUT indicator (red LED) shows transistor state; BEAM STATUS indicator (green LED) confirms received light level
- Range Adjustment: 15-turn potentiometer for precise light source intensity control
- Hysteresis Control: Set for medium-to-low contrast applications with immunity to ambient light
- Polarity Protected: 12–24 VDC supply with integrated protection
