Medical OEM applications, such as surgical table positioning can benefit from position sensors designed for wear-free operation. ASM Sensors PRAS20/PRAS21 series are magnetic rotary sensors that offer wear-free capability. The non-contact position sensors use an external position magnet to provide an absolute output signal over a 0 to 360-degree measurement range.
Key parameters for the sensors include:
- Resolution is rated at 0.03 % of full scale (60…360°) and 0.1 % full scale (15…45°)
- Repeatability is ±0.03 % (60…360°); ±0.1 % (15…45°)
- Linearity is ±0.5% full scale.
The smaller of the two units, the PRAS21 series housing has a height of less than ¼ inch. With an IP60 rating like the PRAS20, it fits into tight medical equipment applications.
