Telemecanique XUB2BKXNL2T Photoelectric Sensor: Technical Overview
The Telemecanique XUB2BKXNL2T photoelectric sensor is a thru-beam photoelectric transmitter designed for industrial automation tasks where reliable long-range detection is required. It is part of the Telemecanique XU sensor range and uses a cylindrical metal body suitable for robust machine integration.
Product Type and Detection Principle
The XUB2BKXNL2T is a transmitter, not a standalone sensor. It works with a compatible receiver to create a thru-beam sensing system. The transmitter projects a beam toward the receiver, and the sensing event occurs when an object interrupts that beam. This method is widely used in automation because it provides strong detection stability across different object colors, textures, and surface finishes.
This model is listed with a nominal sensing distance of 20 m and a maximum sensing distance of 30 m when paired with the appropriate receiver. That makes it suitable for larger conveyors, wide machine openings, and detection points where the sensor pair must span a significant distance.
Technical Characteristics
The Telemecanique XUB2BKXNL2T features a cylindrical metal sensor body, axial line of sight, red LED emission, discrete signal compatibility, DC supply circuit type, and 2-wire wiring technique. It includes a 2 m cable connection, which can be useful for fixed installations where a direct cable run is preferred.
The model is also associated with IP65 and IP67 ratings, supporting use in industrial settings where dust and moisture exposure may occur. Its metal housing helps protect the sensor against mechanical stress, while the M18 format keeps the design compact enough for machine frames and conveyor brackets.
Typical Use Cases
The Telemecanique XUB2BKXNL2T photoelectric sensor is appropriate for conveyor monitoring, object counting, packaging automation, production line control, access point detection, and material handling systems. Its long sensing capability is valuable where the detection path must cover a broad area.
In packaging machinery, it can help confirm that a product has entered or exited a station. In logistics equipment, it can detect boxes or totes crossing a conveyor zone. In manufacturing cells, it can support part presence checks before a robot, actuator, or machine cycle begins.
Installation Considerations
To achieve stable performance, the transmitter and receiver should be aligned precisely. The optical path must remain clear when no target is present. Mounting brackets should be rigid enough to prevent movement caused by vibration. The 2 m cable should be routed away from sharp edges, moving machine parts, and high-power cables.
Regular cleaning is also important. Dust, oil mist, water droplets, or packaging particles on the lens may reduce optical performance. Preventive maintenance should include checking alignment, cable condition, lens cleanliness, and secure mounting.
