Why Use an EMS22 Magnetic Encoder?
The EMS22 can offer enhanced reliability in harsh
environmental conditions such as mud, dust, grease,
oil, water and dirt, giving this product an edge in
performance over traditional optical and contacting
encoders. Figure 4 illustrates examples of harsh
environments.
In addition, there are no contacting parts between
the magnet and the ASSP to degrade the life
expectancy of this type of encoder. As a result,
the EMS22 can have more than 50 times the life
expectancy of traditional contacting encoders.
The designer and end user can expect cycle
life performance without degradation of signal
accuracy, a clear advantage over encoders that use
optical or contacting technology.
