Turck Q42 long-range inductive proximity sensor

Turck has released a long-range inductive proximity sensor, the Q42, that uses FDA-rated materials for wash down applications.

The Q42 - available in a top-facing model and front-facing model - is an addition to the uprox+ range of factor one sensors that require no correction factor to detect any metal type. It is designed for use in applications that require frequent cleaning with chemicals found in food and beverage applications or where the sensor is exposed to wet environments, such as car washes or outdoor applications.

Featuring a durable stainless steel connector, the device has a PA12 thermoplastic housing that is resistant to chemicals and caustic cleaning agents, as well as shock from impact. Additionally, the housing materials are food-safe and meet FDA Regulation 21CFR 177, 1500(9) for the US and FDA/EGVO 1935/2004 for the EU.

The Q42 features integrated pre-damping, providing designers with the flexibility to partially recess the sensor into their design.

The existing uprox+ washdown family is comprised of 12, 18 and 30 mm diameter barrels with sensing ranges between 4 and 30 mm. The Q42 offers a sensing range of 50 mm to all types of metals. This not only eliminates the need to change the position of the sensors for different metal applications, but also reduces the number of sensor types needed for plant operations.

In addition to an extended sensing distance, the Q42 delivers reliable operation in temperatures ranging from -40 to 100°C.
