The IFM MK5904 cylinder sensor with IO-Link provides intelligent position monitoring for short-stroke pneumatic cylinders. The MKT4028BFRKG/H/IO/ZH version combines cylinder-position detection with IO-Link communication for parameterisation and diagnostic information. IFM describes this family as capable of detecting two end positions with one sensor, providing an end-position setting aid and 50 mm detection range for inline cylinder monitoring
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MK5904 is an intelligent cylinder sensor designed for modern pneumatic automation systems. It uses one sensor to monitor the end positions of suitable short-stroke cylinders and communicates additional information through IO-Link. This allows the sensor to become more than a simple switching device. It can provide useful operating and diagnostic information to the automation controller.
IO-Link enables convenient sensor communication, parameterisation and access to diagnostic information. IFM specifies the MK5904 family for user-friendly communication and parameterisation through IO-Link, together with switching-cycle monitoring and diagnostic functions. These capabilities can support condition monitoring and help maintenance personnel identify cylinder-related problems more efficiently.
The MK5904 provides a 50 mm detection range for inline quality monitoring and uses a second LED as an end-position setting aid. The sensor can therefore monitor piston movement over a defined range rather than simply acting as a conventional single-position switch. This makes it useful for applications requiring more information from pneumatic motion.
The MK5904 is suitable for automated pneumatic cylinders in assembly, handling, packaging and production machinery. IO-Link communication can simplify parameter management and provide additional diagnostic information to the control system. Monitoring switching cycles can also support preventive maintenance strategies. The sensor is particularly useful in machines where pneumatic actuator condition and position need to be monitored continuously.
