S3403 is a rectangular magnetic proximity sensor with a hermetically sealed reed contact, actuated by a permanent magnet, and designed for applications requiring high operating distance and IP67 protection. The sensor features a plastic anodized aluminum case, operates between -25 and +100°C, and has a 2 mm cable length with two 0.14 mm² conductors. It provides a NO+NC output with a maximum switching frequency of 250 Hz, rated at 20 VA, 150 V, and 1 A. The operating distance is 10 mm, and it complies with RoHS and 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.
