In its simplest and most common form it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope.
Magnetic proximity switch symbol.
A proximity switch will be in its normal status when it is distant from any detectable object.
By definition these switches are non contact sensors using magnetic electric or optical means to sense the proximity of objects.
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.
Symbols of electronic sensors transducers detectors.
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.
Jic nfpa symbols.
If this is the case a magnet may need to be mounted on the target.

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 contacts are usually normally open closing when a magnetic field is present or they may be.
Standard electrical jic nfpa symbols used to represent contactors thermal overloads motors and transformers for usage in electrical schematic diagrams.
A proximity switch is one detecting the proximity closeness of some object.
For this reason magnetic sensors are sometimes used where a small sensor is needed but the target is not very close.
The transducers sensors and electrical and electronic detectors are elements activated by the energy delivered by a system and that in turn deliver another type of energy to another different system the transformed energy may be of physical chemical or biological origin.
