RS PRO Aluminium Proximity Switch - Pre-wired Reed Switch
RS PRO heavy duty aluminium housed proximity switch is a robust sealed switch with normally open contacts which is suitable for harsh environments.
Reed switches are a type of industrial switch and are used to interrupt or redirect the flow of electricity within a circuit. Reed switches are composed of two ferrous reeds in a small glass casing. The switches are magnetised and move when the magnetic field is moved towards the switch. A reed switch can turn on or off when a magnetic field is nearby.
RS PRO have a great range of industrial magnetic proximity switches and magnetic proximity sensors to suit many different applications.

Linear actuators
Security switching
Safety guards/devices
FAQs
What is a magnetic proximity switch?
Magnetic proximity switches are a type of electromagnetic switch which controls the flow of electricity within a circuit.
What is the difference between a proximity switch and a proximity sensor?
A proximity sensor is a sensor which is able to detect the presence of nearby objects without any physical contact. Proximity switches open or close an electrical circuit when they make contact with or come within a certain distance of an object.
