As Small as a Finger, Magnetic Angle Sensor from ASM Can Fit into Door Hinges

November is Magnetic Sensing Month at Magnetics Magazine!

Stay tuned and check the website frequently for new updates on the latest technology for magnetic sensing.

Narrow and slim installation spaces in industrial applications require special sensor designs especially when they must withstand harsh environmental conditions such as humidity, dirt and intensive cleaning processes. ASM Sensors of Germany has developed a very small new angle sensor for meeting these requirements. 

The posirot PRAS1 is designed in a narrow rod shape that measures only 10.6 mm in diameter and has a length of 53 mm. Due to its slim design, the sensor is suitable for very narrow installation spaces and fits particularly well into door hinges. 

It measures rotational positions from 0 to 360 degrees using a Hall effect sensor array and an external position magnet. The magnetic encoder technology is completely contactless and contains no moving parts, making them shock and vibration resistant. Due to its robustness, the sensor is also suitable for use in applications with difficult ambient conditions such as packaging machines or filling plants. An IP69 version is particularly suitable for applications with intensive cleaning processes in pharmaceutical and food production. 

Based in Moosinning near Munich, ASM has been producing displacement, angle and inclination sensors for more than 40 years. See
