The S3399 is a magnetic proximity sensor with a NO+NC output, featuring a threaded nickel-plated brass case, IP67 protection, and a hermetically sealed reed contact in an inert gas-filled glass bulb. It operates with a magnet and has a maximum switching frequency of 250 Hz for the NO+NC output. The sensor is rated for 20 VA at 150 V and 1 A, with an operating temperature range of -25 to +100°C. It includes a 2 m cable with two 0.14 mm² conductors and is RoHS compliant and EMC compliant. The operating distance depends on the magnet used, as specified in Table 1.
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.
