We produce this square Diffuse Photo Sensor in our own workshop, built exclusively for single-sided installation on automated machinery. Unlike opposed-type sensors that demand two-side alignment, this unit packs both light transmitter and receiver into one compact housing. It works by capturing reflected light off target workpieces to trigger switch signals, making it our most popular pick for glossy plastic, packaging film and metal component inspection. Over years serving equipment integrators, we've found this model drastically cuts wiring and installation time on tight machine layouts.
Features
-
Stable & Fully Sealed Structure
We adopt one-piece injection molding plus mortise-and-tenon sealing structure, reaching full IP67 protection grade. The shell blocks workshop dust, water mist and minor oil splashes, so it runs reliably inside injection molding, food packaging and painting workshops with harsh environmental conditions.
-
Easy Diagnostic Debugging
Two independent indicator lights are mounted on the front: a working action LED and a stability diagnostic lamp. The stability light lets engineers judge if the sensor is set to a reliable threshold during setup, slashing on-site debugging time significantly.
-
Flexible Output Switching
Each sensor supports both normally open and normally closed output signals. Simply rotate the L/D selector knob to switch modes; no wiring replacement or auxiliary modules needed.
-
Precision Adjustable Sensing Range
The front rotary knob controls sensing distance accurately. Rotate toward MIN for short-range detection of tiny electronic components, or turn fully to MAX for long-distance counting on conveyor belts.
-
Strong Anti-Disturbance Circuitry
We embed self-developed anti-interference algorithm chips inside every unit. It suppresses signal interference from strong workshop fluorescent lights, natural sunlight and nearby servo motors/inverters, lowering false trigger rates during mass production.
-
Consistent Optical Calibration
Optical and mechanical axes are calibrated during factory assembly with minimal deviation. After installation, users rarely need repeated position tweaks to hold stable detection accuracy.
Advantages
- Standard square mounting size fits most universal sensor brackets sold worldwide. It can directly replace mainstream brand Diffuse Photo Sensor without redesigning machine mounting holes, saving extra mold processing costs for equipment manufacturers.
- Visible light spot simplifies field alignment. Maintenance staff without professional optical training can locate sensing positions quickly without extra tools.
- Dual-color status LED indicators separate power and trigger signals, so operators can tell real-time working status at a glance several meters away from the equipment.
- IP67 full sealing shell withstands daily industrial dust and liquid splashes, extending service life in tough workshop environments.
- Complete reverse polarity and short-circuit protection prevents accidental damage caused by wiring errors, cutting after-sales replacement costs for our bulk buyers.
- Factory direct pricing without middleman markup, ideal for machine builders and long-term distributors sourcing sensors in large batches.
FAQ
Q: What are the common light sources for the Diffuse Photo Sensor?
The emitters in photoelectric sensors typically use the following light sources:
Red LED: Visible light, easy to adjust and align.
Infrared LED: High-energy invisible light, ideal for applications requiring non-visible detection.
Red Laser: Visible light with precise physical properties, perfect for detecting small objects or achieving long detection ranges.
