SICK WTV4FE-8416A120A00 Photoelectric sensor
SICK WTV4FE-8416A120A00 miniature photoelectric sensor with V-optics, part 1123755. Reliable detection of transparent films, glass and clear plastics.
Overview
The SICK WTV4FE-8416A120A00 (part number 1123755) is a miniature photoelectric sensor with V-optics, designed to detect transparent objects such as films, glass panels and clear plastic parts. Standard diffuse sensors struggle with clear targets because most light passes straight through; the V-lens arrangement solves this by evaluating the reflection at the surface.
How It Works
The V-optics align the emission and reception at a defined angle so that even the weak surface reflection of a transparent object is captured. When the reflected light exceeds the threshold, the output switches. This makes clear targets detectable at short range where conventional optics see nothing.
Key Features
- V-optics for reliable transparent object detection
- Miniature housing for compact machine integration
- Part number 1123755
- Detects glass, PET and clear film at short range
- Insensitive to the object color and print pattern
- Suitable for high-speed web and sheet processes
Typical Applications
- Detection of transparent films on packaging machines
- Glass sheet presence checks on handling systems
- Clear bottle and preform detection on beverage lines
- Double-sheet and film-break monitoring
- Display glass transport monitoring in electronics production

Installation and Setup Notes
Transparent detection depends on geometry: mount the sensor at the recommended angle to the film or glass surface and test with the thinnest production material. Keep the optical faces free of fingerprints and dust, since any soiling reduces the weak signal from clear targets. Verify switching across the full width of web travel.
Frequently Asked Questions
Can it detect clear stretch film?
Yes, V-optics are designed specifically to capture the surface reflection of transparent materials.
Does it also detect opaque objects?
Yes, opaque objects block or reflect more light and are detected reliably within the range.
How close must it be mounted?
Transparent detection works at short range; follow the family distance guidance and test with the real product.
