Resistive push-button switch offers long life and reliable operation
The MSS-IO switch from SCHURTER differs from conventional push-button switches in having no mechanical actuator. Its sealed surface is easy to clean, making the switch ideal for use in hygiene-conscious applications.
SCHURTER has built on its existing MSS push-button switch, launching a new version which includes an IO-Link module to enable bidirectional communication.Â
The MSS-IO, which operates on a wear-free resistance measurement principle, completely eliminates the use of mechanical switching components. Responding to changes in electrical resistance to detect switch actuation, the MSS-IO is sensitive enough to detect the smallest changes in pressure from the user’s finger, but robust enough to withstand the rigors of industrial processes. The absence of moving parts helps to give the MSS-IO long service life.
The switch’s resistive sensing operation allows SCHURTER to make a sealed surface which is unaffected by water, dirt or cleaning substances. This is a valuable feature for applications in areas which have to maintain hygiene, such as food processing or laboratory equipment.Â
The IO-Link interface in the MSS-IO switch allows not only for bidirectional communication, but also for configuration and real-time diagnostics, making the product ready for integration into Industry 4.0 equipment.
