Product Description
The Pepperl+Fuchs SJ3,5-N is an ultra-compact, inductive proximity sensor engineered for high-precision object detection in severely space-limited applications. Its defining characteristic is its miniature M3.5 x 0.35 threaded cylindrical housing, one of the smallest standard form factors available. This design allows for easy integration into compact machinery, small assembly units, and robotic grippers where conventional sensors are too large.A key feature of the SJ3,5-N is its shielded (flush-mountable) design, enabling installation flush with surrounding metal without any reduction in its nominal sensing distance of 2 mm. This simplifies mechanical design and ensures reliable detection of small metal targets. The sensor is available in both Normally Open (NO) and Normally Closed (NC) electronic output configurations, typically as a DC 3-wire device with a 10-30 V DC operating range. It incorporates built-in protection against short-circuits and reverse polarity, enhancing its durability and safeguarding against wiring errors during installation.

Key Features
-
Extremely Compact Size: Miniature M3.5 x 0.35 housing for installation in tight spaces.
-
Flush Mountable: Can be installed flush in metal without loss of switching distance, simplifying mounting.
-
Short-Circuit and Reverse Polarity Protection: Enhances operational reliability and protects against wiring errors.
-
Shielded Design: Ensures stable performance in metallic environments.
-
LED Status Indicator: Provides visual confirmation of switching status and power.
The Pepperl+Fuchs SJ3,5-N is a compact, cylindrical inductive proximity sensor designed for reliable non-contact object detection in highly space-constrained applications. Its miniature M3.5 x 0.35 threaded barrel design makes it perfect for integration into machinery and automated systems where size is a critical factor.
