The S3402 is a rectangular magnetic proximity sensor with a hermetically sealed reed contact, designed for actuation by a permanent magnet. It features a rectangular case made of anodized aluminum, an IP67 protection rating, and operates within a temperature range of -25 to +100°C. The sensor provides a NO+NC output with a voltage rating of 150 V, a current rating of 1 A, and a power rating of 20 VA. Its switching frequency is up to 250 Hz for the NO+NC output, and it includes a 2-meter cable with two 0.14 mm² conductors. The operating distance is 10 mm. The sensor is RoHS compliant and meets the EMC directive.
Magnetic sensors are actuated by the presence of a permanent magnet. Their operating principle is based on the use of reed contacts, which consist of two low reluctance ferro-magnetic reeds enclosed in glass bulbs containing inert gas. The reciprocal attraction of both reeds in the presence of a magnetic field, due to magnetic induction, establishes an electrical contact.
