SICK WTB26P-24161120A00 Photoelectric Sensor
1. Product Overview
The SICK WTB26P-24161120A00 is a photoelectric sensor from SICK’s W26 product family, designed for reliable object detection in industrial automation. Photoelectric sensors use light to detect the presence or absence of objects without requiring physical contact. Depending on the model configuration, they can be used to detect products on conveyor belts, monitor packaging operations, and support automated production processes.
The W26 series is designed for industrial applications that require dependable detection, robust construction, and consistent performance. Before installation, the exact sensing range, output type, connection, and other electrical parameters should be verified against the manufacturer’s datasheet for the complete part number.

Frequently Asked Questions – WTB26P-24161120A00
Q1. What is the SICK WTB26P-24161120A00 used for?
It is used for non-contact object detection in industrial automation, including conveyor systems, packaging machinery, and manufacturing lines.
Q2. What is its maximum sensing distance?
The maximum specified sensing range is 1,600 mm (1.6 metres). The recommended range for best performance is 200–600 mm.
Q3. Does this sensor require a reflector?
No. It is a photoelectric proximity sensor with background suppression, so it detects light reflected from the object itself rather than requiring a separate reflector.
Q4. What is its operating voltage?
It operates on a 10–30 V DC supply.
Q5. Does it support IO-Link?
Yes. It supports IO-Link V1.1 for sensor configuration, process data, and diagnostic information.
Q6. Can it operate in harsh industrial environments?
Yes. Its IP66, IP67, and IP69 ratings and operating temperature range of −40°C to +60°C make it suitable for demanding industrial conditions when installed correctly.
Q7. Where can I buy this sensor in India?
You can enquire through SICK India or check authorized industrial component distributors for availability and pricing.
