Pepperl + Fuchs SJ3,5-N

The Pepperl + Fuchs SJ3,5-N inductive slot sensor is a high-precision device designed to offer reliable detection and monitoring for a wide range of industrial applications. With a slot width of 3.5 mm and a typical immersion depth of 6 mm, this sensor is adept at ensuring accurate operation in environments where precise positioning is crucial.

Crafted with a robust PBT housing, the SJ3,5-N is rated with an IP67 protection degree, making it suitable for use in demanding conditions where dust and moisture resistance is essential. The sensor operates within an ambient temperature range of -25 to 100 °C, ensuring consistent performance even in extreme temperature variations.

This sensor features a NAMUR output type and is compatible with 2-wire connection systems, offering a nominal voltage of 8.2 V. It is designed to work within an operating voltage range of 5 to 25 V and can handle switching frequencies up to 3000 Hz. The hysteresis of 0.41 to 0.6 mm provides stable detection and reduces the risk of false triggering.

The SJ3,5-N is also suitable for use up to SIL2 according to IEC 61508, indicating a high level of reliability and safety for functional safety applications. Its design takes into account the need for low current consumption, with a typical current draw of ≥ 3 mA when the measuring plate is not detected and ≤ 1 mA when detected.

This inductive slot sensor is compliant with several international standards, including NAMUR EN 60947-5-6 and IEC 60947-5-6, ensuring its suitability for global industrial markets. It is a versatile component that can be integrated into various control systems, making it an essential part of automation solutions where precision detection is paramount.
