SICK WTB26P-24861120A00 Photoelectric sensor
SICK WTB26P-24861120A00 diffuse photoelectric sensor, part 1115766. Large W26 housing with strong optical reserves for heavy industry and logistics.
Overview
The SICK WTB26P-24861120A00 (part number 1115766) is a diffuse photoelectric sensor in the large W26 rectangular housing family. Its size accommodates powerful optics and robust electronics, making it suitable for heavy industry, material handling and environments where sensors must withstand rough treatment.
How It Works
Following the energetic diffuse principle, the sensor measures the light reflected by the target and switches when the intensity passes the threshold. The wide optical aperture collects returned light efficiently, providing solid switching margins even when targets reflect weakly.
Key Features
- Large W26 housing with high optical reserves
- PNP switching output (P order code)
- Strong tolerance to vibration and mechanical stress
- Effective detection of weakly reflecting targets
- Connector-based wiring for service-friendly installation
- Sensitivity setting for application adaptation
Typical Applications
- Pallet and large container detection in intralogistics
- Object monitoring on steel, wood and building material lines
- Detection in heavy machinery and mobile equipment
- Presence checks in harsh production environments
- Monitoring of bulky goods on transfer cars and conveyors

Installation and Setup Notes
Use rigid mounting because the large housing presents more surface to airflow and vibration. Align the optical axis with the target path and set the sensitivity with the weakest target in production. For very dark or matte targets at longer distance, confirm the switching margin or select a retro-reflective arrangement.
Frequently Asked Questions
What applications suit the W26 format?
Heavy industry and logistics tasks where robustness and optical reserves matter more than compact dimensions.
Can it be used on mobile equipment?
Yes, its sturdy construction suits mobile and vibrating platforms when mounted with lock nuts and strain-relieved cabling.
Does it switch on dark rubber surfaces?
Yes, at reduced range; validate with the real target at the installation distance.
