The Keyence SH-422 Standard Non-Shielded Cylindrical & Threaded Sensor is a robust and precise inductive proximity sensor engineered for reliable detection of metallic objects in demanding industrial environments. With its √∏22 √ó 35 mm cylindrical body, wide detection capability, and rugged construction, it provides long-lasting performance for automation systems where stability and accuracy are critical.

The SH-422 is designed primarily to detect ferrous metals, such as iron and steel, which are common in manufacturing, assembly, and machine applications. It is calibrated using a standard 25 √ó 25 mm iron target (t = 1 mm), ensuring consistent, predictable results across production environments. In addition to ferrous targets, the sensor can also detect nonferrous metals, with specific detection characteristics provided to maintain stable performance when working with materials like aluminium, brass, or stainless steel.

A key advantage of the SH-422 is its stable detecting range of 0 to 9 mm, providing reliable performance for tasks such as presence/absence detection, part confirmation, or positional sensing. This consistent sensing capability reduces the risk of false triggers, ensuring smooth operation across automated processes.

The sensor also supports an extended maximum detecting distance of 22 mm, giving it the flexibility to be mounted further away from targets while still maintaining reliable detection. This feature is particularly useful in environments where direct proximity installation is not feasible, such as when sensors must be mounted behind protective covers, in recessed positions, or where target movement creates variable spacing.

Its cylindrical threaded body allows for easy and secure mounting into machine frames, brackets, or custom equipment layouts. The √∏22 √ó 35 mm size strikes a balance between compactness and durability, ensuring the sensor fits into standard industrial designs while providing robust housing capable of withstanding mechanical stress and vibration.

The non-shielded design of the SH-422 allows for longer detection ranges compared to shielded models, making it a versatile choice for applications that require more forgiving installation distances. This flexibility simplifies integration into new or existing systems while maintaining high accuracy.

Engineered to Keyence’s rigorous standards, the SH-422 is built for durability and long service life. Its rugged housing is resistant to vibration, shock, and the challenging conditions often found in manufacturing environments. This reliability reduces downtime, minimises maintenance requirements, and ensures long-term cost efficiency.

In summary, the Keyence SH-422 Standard Non-Shielded Cylindrical & Threaded Sensor offers a powerful combination of precision, flexibility, and durability. With its 0–9 mm stable detection range, 22 mm maximum sensing distance, and robust ø22 × 35 mm threaded housing, it provides engineers and operators with a dependable solution for accurate metal detection. For automation systems requiring long-range capability and stable performance, the SH-422 is an excellent choice.
