Proximity Switch Type A

Maximum load current: 0.5A
Load Voltage: 100VDC
Ambient temperature: -10-85 C
Action Distance: Optional between 1 mm (min) - 30 mm (max) on-off distance

Working principle:
The magnetic proximity Switch consists of permanent magnet (trigger part) and reed (induction part). Reed tube, also known as tongue reed tube, is constructed by encapsulating two or more soft iron electrodes in a sealed glass tube filled with inert gas. The induction part is made up of a magnetic spring switch connected by a lead and encapsulated in a finalized form. The trigger part is encapsulated in a plastic or alloy shell by a magnet with corresponding magnetic field strength. When they are separated or close to a certain distance, they cause the switch to open and disconnect, so as to sense the change of object position. It can not only complete the travel control and limit protection, but also is a non-contact detection device, which can be used to detect the size of parts and speed measurement.

Application:
It is used for automobile, industrial control, frequency conversion counter, frequency conversion pulse generator, liquid level control, automatic connection of intelligent household appliances and processing program, etc.

Advantage:
It is small in size, simple in structure, sensitive in action, good in corrosion resistance and long in service life.
