Turck 40102, also known as BI2-M12-Y1X-H1141, is a compact inductive proximity sensor designed for reliable non-contact detection of metal objects in industrial applications. Built in a durable chrome-plated brass M12 x 1 threaded barrel with a plastic sensing face, it offers a 2 mm rated switching distance, flush mounting capability and a fast 5 kHz switching frequency for accurate, repeatable performance in confined installation spaces.
This DC 2-wire NAMUR sensor operates at a nominal 8.2 VDC and features an M12 x 1 male connector for straightforward integration into suitable systems. With IP67 protection and an operating temperature range of -25 to +70 °C, it is well suited to demanding environments where dependable sensing and long-term durability are essential. The unit also includes a yellow LED switching state indication and is approved for use in ATEX Zone 0 and Zone 20 environments.

What does this inductive sensor do?
This device is designed to detect metal objects without physical contact. It uses an electromagnetic sensing field, which helps provide wear-free operation in automated machinery and industrial sensing positions.
What is the rated sensing distance?
The rated sensing distance is 2 mm. Actual sensing performance can vary depending on the target material, installation conditions and surrounding metalwork.
Which materials can it detect best?
It is intended for detecting metal targets. Mild steel provides the reference performance, while aluminium, stainless steel and brass can reduce the effective sensing distance compared with steel.
Is this a flush-mount sensor?
Yes. It is designed for flush mounting, which makes it suitable for compact installations where the sensor body needs to sit neatly within surrounding metal.
What electrical output does it use?
This model uses a 2-wire NAMUR output and operates at a nominal 8.2 VDC. The Turck 40102 is intended for use in NAMUR-style sensor circuits rather than standard 3-wire DC switching arrangements.
What type of connection does it have?
It features an M12 x 1 male connector, allowing it to be paired with compatible female connection leads for straightforward installation.
What is the housing style and material?
The sensor is built in an M12 x 1 threaded barrel format with a chrome-plated brass housing. This style is widely used where secure mounting and a compact cylindrical design are preferred.
Can it be used in dusty or wet industrial environments?
It has an IP67 protection rating, which makes it suitable for demanding industrial environments where resistance to dust ingress and temporary exposure to water is important.
What ambient temperature range can it operate in?
The permitted ambient temperature range is -25 °C to +70 °C, making it suitable for a broad range of indoor industrial applications.
Is there a visual indication of switching status?
Yes. The sensor includes a yellow LED to indicate switching state, which can help during setup and routine machine checks.
How fast can it switch?
This model offers a switching frequency of up to 5 kHz, making it suitable for applications that require fast detection of moving metal components.
Is it suitable for hazardous-area installations?
Yes. This version is marked for use in hazardous areas and carries ATEX protection markings for gas and dust environments, including Zone 0 and Zone 20 applications where the installation requirements are met.
