Telemecanique XUB2AKXNL2T Photoelectric Transmitter: Technical Overview

The Telemecanique XUB2AKXNL2T photoelectric transmitter is a cylindrical M18 thru-beam transmitter from the Telemecanique XU photoelectric sensor range. It is designed for industrial applications where a defined optical path is used to detect objects passing between a transmitter and receiver. This model is commercialized and serves as a current replacement option for older transmitter references in the same family.

Main Technical Characteristics

XUB2AKXNL2T is a photo-electric sensor transmitter with a plastic cylindrical M18 housing, axial line of sight, and thru-beam detection system. It has a sensing range of 0…30 m, with a nominal sensing distance of 20 m when used with a receiver. Unlike earlier infrared emitter models in this group, this unit uses red LED thru-beam emission. The supply circuit is DC, the wiring technique is 2-wire, and the electrical connection is a 2 m cable.

The housing material is PC/PBT and the lens material is PMMA. It includes one green LED for supply indication. The rated supply voltage is 12…24 V DC with reverse polarity protection, while the listed supply voltage limits are 10…30 V DC. The switching capacity is up to 100 mA with overload and short-circuit protection. It has a high switching frequency of 1000 Hz, response delay of 0.5 ms, and recovery delay of 0.5 ms.

Performance in Automation

The Telemecanique XUB2AKXNL2T photoelectric transmitter is well suited for fast production environments where reliable beam-based detection is required. The 1000 Hz switching frequency and half-millisecond response values make it appropriate for applications involving moving packages, passing components, counting points, machine indexing, and material-flow monitoring.

Thru-beam sensing is valuable because the object does not need to reflect light back to the sensor. Instead, the system detects the interruption of a direct beam between transmitter and receiver. This can improve stability when targets vary in color, finish, shape, or surface reflectivity. For consistent performance, the transmitter and receiver must be aligned carefully and mounted securely.

Environmental and Installation Notes

XUB2AKXNL2T is rated IP65 and IP67 according to IEC 60529. It has vibration resistance of 7 gn and shock resistance of 30 gn for 11 ms. Operating temperature is listed from -30 °C to 55 °C, and relative humidity from 35% to 95%. It also has strong immunity to ambient light, listed as 40,000 lux sunlight and 10,000 lux incandescent light.

The 2 m cable connection supports direct wiring into panels, junction boxes, or machine cable channels. During installation, the optical path should remain clear and protected from accidental obstruction. The sensor should also be positioned away from heavy mechanical impact and excessive contamination on the lens.

Selection Perspective

This model is useful when a compact, current, long-range thru-beam transmitter is needed for industrial automation. Its M18 form factor allows practical integration into standard mounting hardware, while the 30 m range provides flexibility for wider machine layouts. The combination of red LED emission, fast switching, and industrial protection ratings makes it a strong fit for modern packaging, handling, and production equipment.
