Telemecanique XS618B4PAL2 Inductive Proximity Sensor Overview

The Telemecanique XS618B4PAL2 inductive proximity sensor is a general-purpose M18 metal-detection sensor from the XS6 family. It is designed for industrial environments where reliable, non-contact sensing is required. With a 12 mm nominal sensing distance, a cylindrical threaded housing, and a 2-meter cable connection, this model is often selected for machinery, conveyors, equipment monitoring, and metal part detection.

Unlike mechanical switches, an inductive proximity sensor does not need physical contact with the object being detected. This helps reduce wear, avoids mechanical bounce, and supports faster switching in repetitive automation tasks. The XS618B4PAL2 is especially useful when the target is metallic and the installation needs a compact, robust sensor body.

Telemecanique XS618B4PAL2 Main Technical Features

The Telemecanique XS618B4PAL2 has an M18 cylindrical design with a metal body and a 64 mm length. It is non-flush mountable, meaning the sensing head should be installed with the correct free zone around it. The nominal sensing distance is 12 mm, and the detection face is frontal.

This sensor uses a 3-wire DC wiring technique and a PNP normally open output. The supply voltage is 12 to 48 V DC with reverse polarity protection. Its switching capacity is up to 200 mA DC, and it includes overload and short-circuit protection. These details make the XS618B4PAL2 suitable for many PLC-based systems that use sourcing sensor outputs.

The sensor is supplied with a 2-meter cable, which can be useful in installations where a direct cable exit is preferred over a connector. The cable version may reduce connector points in areas where vibration, contamination, or frequent movement are concerns. Protection ratings include IP68 and IP69K, supporting demanding environments where moisture, dust, and washdown exposure may be present.

Typical Applications

The XS618B4PAL2 can be used to detect metal machine parts, confirm tool presence, verify actuator position, monitor conveyor movement, or check whether a metallic object is in place before the next process step. Because the output is PNP normally open, it is commonly used with PLC input modules configured for sourcing signals.

This model is a practical fit for automation panels, mobile equipment, packaging machines, handling systems, and industrial production lines. For more information about Telemecanique, engineers and maintenance teams can compare related components and product families.

Installation Considerations

Since the XS618B4PAL2 is non-flush mountable, it should not be surrounded too closely by metal. Incorrect mounting may reduce range or cause unintended operation. The sensor should be aligned so the metallic target approaches the sensing face in a predictable way. Target material also matters: steel usually gives the strongest response, while other metals can reduce effective sensing distance.

The cable should be routed carefully, especially near motors, drives, and high-current conductors. Although the sensor is built for industrial use, proper wiring practice helps maintain signal quality and long-term reliability.

Frequently Asked Questions

What is the Telemecanique XS618B4PAL2?

It is an M18 inductive proximity sensor designed to detect metallic objects without physical contact.

What output does the XS618B4PAL2 provide?

It provides a PNP normally open output using a 3-wire DC configuration.

Does this sensor use a connector?

No. The XS618B4PAL2 is supplied with a 2-meter cable, which makes it different from M12 connector versions in the same family.

What is the nominal sensing distance?

The nominal sensing distance is 12 mm, although practical sensing distance can vary with target size, metal type, and installation conditions.

Can it be used in wet or dusty areas?

Yes. Its IP68 and IP69K ratings make it suitable for many harsh industrial environments, including areas exposed to moisture or washdown.

Is the XS618B4PAL2 flush mountable?

No. It is non-flush mountable and requires suitable clearance from nearby metal for stable detection.
