Telemecanique XUB2AKSNM12T Photoelectric Transmitter: Technical Guide

The Telemecanique XUB2AKSNM12T photoelectric transmitter is a cylindrical M18 thru-beam emitter from the Telemecanique XU photoelectric sensor range. It is designed for non-contact industrial detection systems that require a separate transmitter and receiver. In this arrangement, the transmitter emits an infrared beam toward the receiver, and detection occurs when an object interrupts that beam.

Telemecanique XUB2AKSNM12T Core Specifications

XUB2AKSNM12T has a plastic cylindrical M18 body, axial line of sight, infrared thru-beam emission, and DC supply circuit. It operates on 12…24 V DC with reverse polarity protection. The device uses a 3-wire wiring technique and is equipped with a 4-pin male M12 connector. This connector format is valuable in machinery where fast replacement, modular cabling, and clean sensor installation are priorities.

The enclosure is made from PBT, while the lens is PMMA. The unit includes a green LED for supply indication. It has solid-state output, up to 100 mA switching capacity with overload and short-circuit protection, 500 Hz switching frequency, 1 ms response delay, 1 ms recovery delay, and 15 ms first-up delay. These values support dependable detection timing in automated handling and production processes.

Where It Is Used

The Telemecanique XUB2AKSNM12T photoelectric transmitter is suited for applications where long-range or highly reliable beam interruption detection is preferred. Typical uses include conveyor monitoring, package detection, object counting, machine safety-adjacent presence checks, transfer stations, elevator or escalator equipment monitoring, and industrial line control.

Because the transmitter is part of a thru-beam system, it must be paired with a compatible receiver. This arrangement can perform well with objects of different colors, surfaces, and shapes because the principle is based on beam interruption rather than light reflected from the object itself. Correct alignment is essential. The transmitter and receiver should face each other accurately and remain mechanically stable after commissioning.

Environmental Strength

XUB2AKSNM12T has IP65, IP67, and IP69K protection ratings, giving it a strong environmental profile for demanding industrial settings. It also has vibration resistance of 7 gn and shock resistance of 30 gn for 11 ms. These details matter in installations exposed to machine vibration, washdown routines, dust, or frequent production movement.

The M12 connector version can be especially useful when maintenance teams need to replace sensors quickly without rewiring. It also helps standardize cabling across machinery. During installation, cable routing should avoid sharp bends, mechanical compression, and high-noise power wiring where possible.

Lifecycle and Replacement

The manufacturer lists XUB2AKSNM12T as end of commercialization and identifies XUB2AKXNM12T as its replacement. For existing systems, this code remains important in service records, panel drawings, spare-part lists, and maintenance manuals. For new equipment, the replacement part should be reviewed to confirm mechanical, electrical, and optical compatibility.

It is a Telemecanique cylindrical M18 photoelectric transmitter used in thru-beam detection systems. It emits infrared light toward a compatible receiver.

Does XUB2AKSNM12T detect objects by itself?

No. It is the transmitter side of a thru-beam system. A compatible receiver is required to detect beam interruption and provide the sensing result.

What connector does this model use?

It uses a 4-pin male M12 connector. This supports modular industrial wiring and quicker maintenance compared with fixed cable-only designs.

What protection ratings does it have?

It is listed with IP65, IP67, and IP69K protection ratings, making it suitable for many dusty, wet, or washdown-prone industrial environments.

What is the replacement for Telemecanique XUB2AKSNM12T?

The manufacturer lists XUB2AKXNM12T as the replacement. Compatibility should always be verified before substitution in an existing machine.
