MK5251 is a high-protection T-slot cylinder sensor with a GMR sensing cell. It provides two normally open PNP outputs for position detection. The sensor operates from 10…30 V DC and supports 6000 Hz switching. IP65, IP67 and IP69K protection makes it suitable for demanding washdown environments. Its two short PVC cable sections and M12 connection provide flexible machine integration.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
MK5251 uses a GMR cell for reliable magnetic piston detection. Its magnetic sensitivity is 2.8 mT. The sensor provides two normally open outputs. This allows dual position information from one sensor assembly. The 6000 Hz switching frequency supports fast pneumatic movement.
The sensor provides IP65, IP67 and IP69K protection. This makes it suitable for demanding cleaning and washdown environments. The operating temperature range is -25…85 °C. The housing uses PA with a stainless-steel fastening clamp. These characteristics support food and beverage machinery.
MK5251 measures 25 × 5 × 6.5 mm. The self-clamping fastening system supports quick T-slot mounting. Two 0.3 m PVC cables are provided. The connection uses an A-coded M12 connector. Two rubber positioning stops and cable clips are included.
