Linear Position Sensor Output Types – Which do I choose?

Linear position sensors are available with a variety of different output signal types to suit various application requirements and control architectures.  Let’s take a look at three of the most common output signal types for linear position sensors; 1) analog, 2) time-based digital, and 3) serial digital, and discuss some of the pros and cons of each.

Understanding “True Analog” Resolution

Many distance measurement sensors – regardless of the front-end sensing technology employed – deliver an analog output such as 0-10V or 4-20mA.   A key parameter to understand for any distance measurement sensor is the output resolution.   In a position measurement system, resolution is defined as:
