Diffuse photoelectric sensors consist of an emitter and receiver combined into a single compact housing. They sense presence, color, or contrast by emitting a light beam and sensing the light reflected directly from the target. They are easy to install and adjust but have short sensing distances.

Diffuse
Category Selection
Diffuse photoelectric sensors feature an integrated emitter and receiver in a single compact housing. These sensors detect presence, distance, color, or contrast by emitting a light beam and sensing the light reflected directly from the target. They offer reliable performance, simple installation, and easy adjustment, but their sensing distances are typically shorter.

Distance Measuring Sensors
Newest Additions!
- Wenglor OPT25 series laser distance measurement photoelectric sensors
Wenglor distance measuring sensors can measure the distance of objects at long ranges using a time of transit calculation. For shorter distances, higher-resolution CMOS technology models are suitable. The OPT25 series uses triangulation to measure distances with extreme accuracy and offers our best-in-class distance sensing for ranges within 1 meter.
- High-resolution, short-range models use triangulation for sensing distances up to 1000mm
- Long-range models use time of transit for measuring distances up to 100 meters
- Analog and switching output options
- Class 1 and 2 laser options
- Select models provide IO-Link v1.1 compatibility
- Select models support Bluetooth configuration
- Select models can reliably detect tiny objects with a reproducibility up to 0.8µm
- IP67 or IP68 protection rating
Starting at
$384.00
(OPT2011)
Color Sensors
Wenglor OPT color sensors reliably select colored objects in automated high-speed processes based on previously defined reference colors. The sensor pulsed white light is insensitive to extraneous light and makes reliable color recognition possible even at varying scanning distances.
- 30 to 40 mm sensing distance
- Capable of evaluating up to 3 colors simultaneously
- Single lens optics allows this sensor to have a small spot diameter and large working range
- Reflex mode operation
- 3 NPN/PNP switching outputs
- Teach-in sensitivity adjustment
- 1.6 kHz switching frequency
- 8-pin M12 connection
- IP68 protection rating

Contrast Sensors
Contrast sensors are photoelectric sensors that determine contrast by sensing reflected white or RGB light (red, green, blue) to detect the difference in the wavelength of the reflected light between the mark and the background. Industrial applications include packaging lines, beverage and bottling lines, paper and printing machinery, and ceramics printing.
- Wenglor and DataLogic brands
- Up to 18mm sensing distance
- Vertical or horizontal spot orientation
- Teach-in sensitivity adjustment
- Selectable light on/dark on output state
- Up to 50 kHz switching frequency
- Aluminum, plastic, or stainless steel housings
- Up to IP69K protection rating
