The Turck 1608901, also identified as BI5U-Q08-AP6X2, is a compact rectangular inductive sensor designed for contactless detection of metal objects in industrial automation applications. Its uprox Factor 1 technology provides a consistent rated switching distance of 5 mm across different metals, while offering strong resistance to magnetic fields.
The sensor features a low-profile 32 × 20 × 8 mm nickel-plated Zamak housing with a top-facing active area, making it suitable for flush installation where space is limited. It operates from 10 to 30 V DC and uses a three-wire PNP normally open output, supporting a rated operating current of up to 200 mA and a switching frequency of 0.25 kHz.
An integrated 2 m PUR cable provides the electrical connection, with green and yellow LEDs indicating power and switching status. Rated to IP68 and capable of operating in ambient temperatures from -30°C to +85°C, the Turck 1608901 is well suited to demanding machinery, material-handling and factory automation environments.

What type of device is this?
It is a rectangular inductive proximity sensor designed for contactless detection of metal objects in industrial automation applications.
What is the rated switching distance?
The rated switching distance is 5 mm. Its secured operating distance is up to 81% of the rated distance.
Can it detect different types of metal?
Yes. The Factor 1 sensing design enables it to detect different metals at the same rated switching distance.
What electrical output does the sensor use?
The sensor has a three-wire PNP normally open output and operates from a 10–30 V DC supply.
What is the maximum rated operating current?
The maximum rated operating current is 200 mA. No-load current is no more than 15 mA, and residual current is no more than 0.1 mA.
Is the sensor suitable for flush mounting?
Yes. Turck 1608901 is designed for flush installation, allowing its sensing face to be mounted level with surrounding metal.
What are the sensor's dimensions?
The rectangular housing measures 32 × 20 × 8 mm, making it suitable for installations where mounting space is limited.
What environmental protection rating does it have?
It has an IP68 protection rating, indicating a sealed design suitable for demanding industrial environments.
What operating temperature range is specified?
The specified ambient operating temperature range is -30°C to +85°C.
How is the sensor electrically connected?
It is supplied with a 2 m grey PUR cable measuring 3 mm in diameter. The cable contains three conductors, each with a cross-sectional area of 0.14 mm².
Does the sensor include status indicators?
Yes. A green LED indicates power, while a yellow LED shows the switching state.
What is the maximum switching frequency?
The specified switching frequency is 0.25 kHz, equivalent to 250 switching cycles per second.
Is it resistant to magnetic fields?
Yes. The sensor is rated for field stability up to 300 mT for both DC and AC magnetic fields.
What materials are used in its construction?
The housing is made from nickel-plated Zamak metal, while the yellow active sensing area is made from polypropylene.
What electrical protection features are included?
The design includes cyclic short-circuit protection, complete reverse-polarity protection and wire-break protection.
Is the cable suitable for moving applications?
The PUR cable is specified as suitable for energy-chain systems in accordance with the relevant manufacturer's declaration.
