## Description

This magnetic switch (reed switch) consists of two magnetic reeds (usually composed of iron and nickel) sealed in a plastic case. The two magnetic reeds are overlapped but there is a small gap between them. When a suitable external magnetic field comes within 2cm, the two magnetic reeds will contact and conduct, thereby sensing the change in the position of the object.This magnetic control switch has a compact structure and a small weight, which can be installed in a limited space, and is extremely suitable for using in miniaturized equipment. The switching elements of the reed switch are hermetically sealed in an inert gas atmosphere so that they are never exposed to the external environment and feature a long service life. The switch can be widely used in door/window position limiting device, proximity switches, measuring instruments, automation/security/transportation equipment, smart homes, etc.FeaturesCompact structure and small weightLong service lifeWide voltage operating rangeSpecificationOperating Voltage: 0~100VOperating Principle: magnetic sensorOutput Signal: switching value signalSize: 6x20x350mm/0.24*0.79*13.78”Color: blackDocumentsProduct wikiShipping ListMagnetic Switch x1Sensor Adapter x1Sensor Data Cable x1
