RS PRO Rectangular Proximity Reed Switches


RS PRO range of rectangular magnetic proximity reed switches which provide a simple and cost-effective solution to position or limit sensing applications. Reed switches are often employed to carry out such functions as linear actuator switches, security system switches and door switches.
Options include:
811-0748 - Proximity Switch - Reed based changeover contacts
811-0736 - Proximity Switch - Normally Open Contacts
811-0745 - Rectangular Encapsulated Magnet

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.

Features and Benefits:


Moulded switch case with 2 slotted fixing holes
Robust sealed switch

Typical Applications:


Reed Proximity Switches and Proximity Sensors (also known as magnetic sensors) are popular due to their reliability and simple design.
Magnetic proximity switches are a type of electromagnetic switch which controls the flow of electricity within a circuit. Magnetic proximity switches can be used in the following applications:
Position sensing
Linear actuators
Security switching
Door Switch

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.
