Retroreflective sensors bounce light off a fixed reflector and determine a target's presence when it breaks the beam. They have longer sensing distances than diffuse sensors but require alignment. Polarized retroreflective sensors improve detection accuracy by filtering out ambient light sources.

Retroreflective Sensors
Category Selection
Retroreflective sensors bounce light off a fixed reflector and determine a target's presence when it breaks the beam. They are easier to install and typically more cost-effective than through-beam sensors, and they offer longer sensing ranges than diffuse sensors. Polarized retroreflective sensors improve detection accuracy by filtering out ambient light sources, ensuring consistent and reliable performance even in difficult lighting conditions.

(FBP-DP-0E)
Miniature Rectangular
New!
Autonics BTS series miniature photoelectric sensors feature ultra-slim, narrow housings that are only 7.2mm wide. They are easy to install in tight spaces, offer fast response times and robust performance, and provide accurate and reliable sensing for challenging industrial applications.
- Sensing distance up to 200mm
- Light-on or dark-on operating modes
- Visible red light emission
- PBT thermoplastic housings
- IP67 protection rating
Priced at
$84.00
(BTS200-MDTL)
Clear Object Detection Sensors
Clear object detection photoelectric sensors reliably detect the presence of transparent or semi-transparent objects, such as glass or plastic. They use increased sensitivity to detect slight changes in light intensity or use specific light wavelengths, such as ultraviolet (UV) light, which is more readily absorbed by transparent materials, to make detection easier.
- AutomationDirect, Contrinex, Eaton, and Wenglor brands
- Sensing distance up to 6m
- Complementary light-on/dark-on or selectable light-on/dark-on operating modes
- AC and DC powered options
- Visible red, infrared, and ultraviolet light emission options
- IO-Link on select models
- Select models are Ecolab approved for use in hygienic areas
- Up to IP69K protection ratings
Starting at
$54.00
(TRR-C23PA-TMK-603)
Distance Measuring Sensors
Wenglor OPT distance measuring sensors measure the distance of objects at long ranges using a time of transit calculation.
- 0.2-100.2 m sensing distance
- 1-100/s measuring rate
- Class 1 red laser
- Selectable light-on/dark-on
- 0 to 10 VDC, 4 to 20 mA, and NPN/PNP output options
- Teach-in button
- Rugged polycarbonate housing
- 8-pin M12 quick-disconnect
- IP68 protection rating
