RSRC-1 Tri-Tronics Clear Object Sensor
Tri-Tronics RSRC-1 Retroreflective Clear Object Sensor
The RSRC-1 is a Tri-Tronics SMARTEYE RetroSmart retroreflective sensor for clear object detection — coaxial polarised optics, 2.4 m maximum range, red LED, with both NPN and PNP outputs on a 5-pin M12 pigtail.
Product Overview
The Tri-Tronics RSRC-1 is a retroreflective photoelectric sensor built specifically for detecting clear and transparent objects — glass and PET bottles, film, and clear packaging — which defeat ordinary photoelectric sensors because so little light is reflected or blocked.
It works on coaxial polarised reflection: the emitted beam is polarised, and the receiver accepts only light whose polarisation has been rotated by the prism reflector. A shiny or transparent object in the path changes the returned light enough to trigger reliably, while a glossy surface behind the target cannot be mistaken for the reflector.
Both NPN and PNP outputs are provided, so it suits either PLC input type without changing the part.

RSRC-1 — Frequently Asked Questions
Q1. Does the RSRC-1 need a reflector?
Yes. It is retro-reflective, so a prism reflector is mounted opposite the sensor. Reflector size affects usable range — see the linked reflector catalogue or ask us to pair one.
Q2. Why use this instead of a standard photoelectric sensor?
Clear objects transmit almost all the light a standard sensor relies on. The coaxial polarised optics detect the small change a transparent object makes, which an ordinary diffuse or reflective sensor cannot resolve reliably.
Q3. Can it be wired to either a PNP or NPN input?
Yes — both output types are provided on the same unit, so it suits either PLC input without changing the part number.
Q4. Do you provide a GST invoice and ship outside India?
Yes to both. Every order carries a GST invoice valid for input tax credit, and we ship to 220+ countries with full export documentation.
