Stable synchronization motor coder HEML15Q0002
Product Introduction
The AC asynchronous motor encoder includes dual speed sensors, AC motor encoder, and encoder assembly. It mainly
uses Hall or giant magnetoresistance element integrated circuits (bias magnetic field) to detect and measure the micro
field changes caused by rotating gears or magnets, thereby achieving speed measurement and direction determination
functions. The casing of this type of sensor is made of special materials, which have the advantages of high strength and
excellent temperature resistance. The accompanying accessories also increase the sensing distance of the product to a
certain extent, making the overall reliability, stability, and wider range of use of the product more reliable. Its advantages
are highlighted in the following aspects:
Strong sensing ability, ranging from 10Hz-20KHz
The product complies with ROHS standards
Protection level reaches IP67
Can customize different external dimensions and performance parameters
