Magnetic Proximity Switch Symbol

A proximity switch is one detecting the proximity closeness of some object.

Magnetic proximity switch symbol.

The contacts are usually normally open closing when a magnetic field is present or they may be. Magnetic proximity sensors are used for non contact position detection beyond the normal limits of inductive sensors. Even small magnetic proximity sensors often have sensing ranges much greater than many inductive proximity sensors. By definition these switches are non contact sensors using magnetic electric or optical means to sense the proximity of objects.

Standard electrical iec symbols also known as iec 60617 british standard bs 3939 used to represent various devices including pilot lights relays timers and switches for usage in electrical schematic diagrams. The reed switch is an electrical switch operated by an applied magnetic field it was invented at bell telephone laboratories in 1936 by walter b. If this is the case a magnet may need to be mounted on the target. A proximity switch will be in its normal status when it is distant from any detectable object.

In conjunction with a separate damping magnet magnetic sensors offer very long sensing ranges from a small package size and can detect magnets through walls of non ferrous metal stainless steel aluminum plastic or wood. For this reason magnetic sensors are sometimes used where a small sensor is needed but the target is not very close. Standard electrical jic nfpa symbols used to represent contactors thermal overloads motors and transformers for usage in electrical schematic diagrams.

In its simplest and most common form it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope. Jic nfpa symbols.
