Telemecanique XT518B1FBL2 Capacitive Proximity Sensor Guide

The Telemecanique XT518B1FBL2 capacitive proximity sensor is an M18 cylindrical sensor designed for non-contact detection of insulated and conductive materials. It is part of the XT capacitive proximity sensor family and is typically used in industrial automation systems where reliable object or material detection is required without mechanical wear.

Technical Profile

The XT518B1FBL2 is a flush-mount capacitive sensor with a 5 mm nominal sensing distance, a 2-wire AC output, and a 2-meter cable connection. It operates on 24 to 240 V AC and is supplied with a normally closed output function, making it suitable for circuits where the signal is active until the target is detected. The product is listed as an M18 capacitive proximity sensor for insulated or conductive material detection.

Design and Protection

This sensor uses a cylindrical M18 threaded body and a fixed detector structure. Its brass housing supports mechanical durability, while its IP67 protection rating allows use in many dusty or moisture-prone industrial environments. The 2-meter cable simplifies installation in panels, conveyors, packaging machines, and material handling equipment.

Application Areas

The Telemecanique XT518B1FBL2 capacitive proximity sensor is useful for detecting plastic containers, paper stacks, glass parts, liquid levels, powders, granules, and metallic objects. Unlike inductive sensors, capacitive models can respond to a broad range of materials, making this model practical for applications where the target is not always metal.

FAQ

What is the Telemecanique XT518B1FBL2 used for?

It is used for detecting conductive and non-conductive materials in automation systems, including packaging, conveyor control, level detection, and machine monitoring.

Is the XT518B1FBL2 normally open or normally closed?

The XT518B1FBL2 is a normally closed sensor. This means the output state changes when the target enters the sensing zone.

What is the sensing distance?

The nominal sensing distance is 5 mm, though real-world performance may vary depending on the material, target size, moisture, mounting position, and surrounding machine structure.

Can it detect plastic or liquid?

Yes. As a capacitive proximity sensor, it can detect many non-metallic materials, including plastic, liquid, powder, paper, and glass, when correctly adjusted and installed.

Does it use a cable or connector?

This model uses a 2-meter cable connection, which is practical for direct wiring into industrial control cabinets or machine wiring systems.
