The IFM MK501A T-slot cylinder sensor is designed for accurate and repeatable piston-position detection on pneumatic cylinders. Its magnetic sensing principle provides non-contact detection, while the PNP normally-open output enables straightforward connection to industrial control systems. With a compact design and 0.3 m cable configuration, the sensor is suitable for automated pneumatic machinery and production equipment.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
MK501A is a T-slot cylinder sensor designed for direct installation on compatible pneumatic cylinders. It detects the magnetic field of the cylinder piston and provides a switching output. The sensor has a compact 25 × 5 × 6.5 mm design and uses PNP normally-open switching.
The sensor operates from 10–30 V DC and has a current consumption below 10 mA. It provides a 100 mA permanent current rating and a switching frequency of up to 10,000 Hz according to the available IFM documentation. Short-circuit and overload protection help support reliable operation in industrial control systems.
MK501A is suitable for pneumatic cylinder position monitoring in automated machinery. It can be used to detect cylinder movement, extension and retraction positions. Typical applications include assembly machines, packaging systems, material handling equipment and production lines. The 0.3 m cable configuration can simplify connection in compact installations.
MK501A combines compact T-slot mounting with fast magnetic switching and PNP output. Its non-contact detection principle avoids mechanical contact with the moving piston. The sensor is therefore suitable for repetitive pneumatic automation tasks requiring reliable position feedback.
