Overview
The Xike WTB26P-X01 (order number 1131855) is a diffuse reflectance photoelectric sensor with background suppression function. It uses a visible red light source, integrates the transmitter and receiver into one, and has an adjustable detection distance of 30 to 350 millimeters. Its core advantage lies in the use of angle measurement principle, which can accurately identify objects within a set distance, ignoring high reflective backgrounds behind. PNP output with a response time of less than 0.5 milliseconds, suitable for precision detection in short distances and complex backgrounds such as electronics and packaging.

Product Overview
WTB26P-X01 belongs to the Sik 26 series photoelectric sensor family. Unlike the previously introduced reflective type, it is a photoelectric proximity sensor with background suppression function.
Type: Diffuse reflection photoelectric switch with background suppression.
Structure: Single body type (transmitter and receiver integrated in the same housing).
Core advantage: It is not affected by the color or material of the detected object, and can accurately block background interference.
Working principle and theoretical core
1. Background suppression principle
Traditional diffuse reflectance sensors rely on detecting the intensity of reflected light to determine if there is an object, which can result in black objects being unable to detect light absorption and white backgrounds having strong reflections, leading to false triggering.
WTB26P-X01 adopts the principle of angle measurement:
The sensor uses a Position Sensitive Detector (PSD) internally.
It determines the distance of an object based on the incident angle of the reflected light on the receiver, rather than solely relying on the light intensity.
After setting the detection distance, the real-time reflectance of the background is high (such as white walls or stainless steel), and the sensor will not respond as long as it is outside the set distance.

Detailed explanation of functional features
1. High precision background suppression
Regardless of whether the background is a bright white wall, mirrored metal, or a running conveyor belt, as long as the object is within the set distance, the sensor only recognizes the object and does not recognize the background.
Black and white attenuation is extremely small: the distance difference between black and white objects can be controlled within 5%.
2. Visible red light source
The emitter emits visible red light, and the spot is clearly visible.
During debugging, you can directly see where the light spot falls, making it extremely convenient to align with objects without the need for additional tools.
3. Mechanical and Electrical Design
Shell: Compact square with M3 mounting threaded holes, compatible with multiple brackets.
Indicator light: Large LED on the side, with clear status at a glance.
Potentiometer: 270 ° high-precision adjustment knob, which can finely set the detection distance.
Typical application scenarios
1. Electronics and Semiconductors
Detect small black chips on the tray with a white reflective ceramic background.
2. Food and Packaging
Check the colored packaging box in front of the transparent film, ignoring the metal frame of the conveyor belt at the back.
3. Automotive components
Detect the black rubber seal ring with a silver vibrating disc as the background.
4. Logistics sorting
Detect packages of different colors, ignoring high-speed conveyor belts.
