Frequently asked questions

What are the three primary types of contacting technologies for valve position feedback?

The three primary types are wirewound, conductive polymer, and Bourns Hybritron technologies.

What is the main advantage of non-contacting technology over contacting technology?

Non-contacting technology provides a longer sensor life because the wear and tear associated with mechanical contact is eliminated.

Which communication protocols are mentioned for interrogating sensors?

Popular protocols include Synchronous Serial Interface (SSI), Serial Peripheral Interface (SPI), Controller Area Network (CAN), and Pulse-Width Modulation (PWM).
