Telemecanique XUB2BKSNL2T Photoelectric Sensor: Technical Overview
The Telemecanique XUB2BKSNL2T photoelectric sensor is an industrial thru-beam transmitter from the Telemecanique XU range. It is designed for presence detection, object passage monitoring, and automation control in machinery where stable beam transmission is required. Built in a cylindrical M18 metal housing, this sensor is suitable for installations that need a compact, durable, and easy-to-mount sensing component.
Product Type and Core Function
The Telemecanique XUB2BKSNL2T is a photoelectric sensor transmitter. In a thru-beam system, the transmitter sends light toward a compatible receiver. When an object breaks the beam, the receiver changes output state. This makes the sensor useful for detecting parts, packages, pallets, containers, and moving items on production lines.
This model is associated with 1224 VDC supply, axial line of sight, discrete signal operation, and a 2 m cable connection. Its M18 cylindrical body allows straightforward mounting on brackets, machine frames, and conveyor structures. The metal construction gives the sensor additional mechanical strength for demanding industrial environments.
Technical Characteristics
Key technical details include thru-beam detection, M18 barrel design, metal housing, axial optical alignment, and DC supply operation. The cable connection helps simplify fixed installations where the sensor is expected to remain in place for long periods. The model is also linked with IP65 and IP67 protection ratings, supporting use in dusty or moisture-prone areas when installed correctly.
The XUB2BKSNL2T is often referenced with a detection range of 15 m when paired with the correct receiver. This range makes it suitable for medium-distance industrial detection points, especially where the target object may vary in color, surface finish, or material. Because thru-beam sensing does not rely on light reflection from the object itself, detection stability can be stronger than diffuse sensing in many practical conditions.
Common Industrial Applications
The Telemecanique XUB2BKSNL2T photoelectric sensor can be used in conveyor monitoring, product counting, machine entry detection, packaging equipment, material handling systems, and process automation. It is particularly effective when the detection zone must remain consistent despite changing product appearance.
For example, in packaging lines, a thru-beam transmitter and receiver can confirm that a carton has passed a specific point before a sealing, labeling, or sorting process begins. In material handling, it can detect object movement across a conveyor without needing physical contact. This helps reduce mechanical wear and supports faster response in automated systems.
Installation Notes
Correct alignment is essential. The transmitter should face the compatible receiver directly, and both components should be mounted firmly to avoid vibration-related signal loss. The lens should be kept clean, especially in environments with dust, oil mist, paper fibers, or packaging debris. Cable routing should also be planned carefully to avoid mechanical strain or electrical noise exposure.
