Telemecanique XUB0BKSNL2T Photoelectric Transmitter: Technical Overview
The Telemecanique XUB0BKSNL2T photoelectric transmitter is a cylindrical M18 through-beam sensor component designed for industrial object detection. It belongs to the Telemecanique Photoelectric Sensors XU range and is used as the emitting unit in a through-beam sensing pair. In this arrangement, the transmitter sends an infrared beam toward a receiver, and object detection occurs when the beam is interrupted.
Telemecanique XUB0BKSNL2T Design and Detection Principle
This model uses a thru-beam detection system, which is widely recognized for long sensing ranges and strong operational stability. Unlike diffuse sensors that depend on light reflected from the target, a through-beam system works with a dedicated transmitter and receiver. This makes the XUB0BKSNL2T suitable for applications where accurate presence detection is required over longer distances.
The sensor has a cylindrical M18 body and an axial line of sight. Its metal housing supports use in industrial environments where vibration, mounting pressure, and general mechanical exposure may be present. The compact M18 format also makes it practical for machinery with limited mounting space.
Telemecanique XUB0BKSNL2T Electrical and Connection Features
The XUB0BKSNL2T is a DC photoelectric transmitter with a 3-wire wiring technique. It is supplied with a cable connection, which is useful when a direct wired installation is preferred over connector-based wiring. The supply voltage is typically used in the 12 to 24 VDC industrial control range, supporting common automation panels and machine control systems.
Because this unit is the transmitter side of the sensing system, it does not operate like a standard output sensor by itself. It must be paired with a compatible receiver to create a complete through-beam detection setup.
Typical Industrial Applications
The Telemecanique XUB0BKSNL2T photoelectric transmitter is commonly used in conveyor monitoring, packaging machinery, object passage detection, product counting, and material handling equipment. Through-beam detection is especially useful when the target may vary in color, finish, or reflectivity, because the system detects interruption of the light path rather than relying on target reflection.
In automated production lines, this can help improve detection consistency for cartons, bottles, components, trays, and irregularly shaped items. It is also a practical choice for machine builders who need a compact emitter for precise optical alignment.
Installation Notes
Correct alignment between the transmitter and receiver is essential. The optical axes should face each other directly, with stable mounting on both sides of the detection path. The sensing range depends on the paired receiver, installation conditions, environmental contamination, and alignment quality.
