Product catalog summary
Overview: The document describes the Vishay MCB POPR27, a single-turn continuous rotation analog displacement sensor utilizing conductive plastic potentiometer technology. It features infinite resolution, a servo mount anodized light alloy housing, precious metal contacts, and stainless steel shaft and bearings. It adheres to standards NFC 93255 and MIL R 39023.
Specifications:
  • Electrical: Theoretical electrical travel (TET) is 345° ± 3°, with options for other angles on request. Total resistance options are 4.7 kΩ or 10 kΩ with a tolerance of ± 20%. Power rating at 70°C is 1.25 W, and the temperature coefficient is -300 ± 300 ppm/°C. Insulation resistance is ≥ 1 GΩ at 500 VDC, and dielectric strength is 750 VRMS.
  • Mechanical: The sensor allows for 360° continuous mechanical rotation. It has a moment of inertia ≤ 0.4 g cm² for one stage and ≤ 0.2 g cm² per additional stage. The protection class is IP 50, and the weight is < 18 g for one stage.
  • Performance: Operating temperature range is -55°C to +125°C, with a life expectancy of 25 million cycles and a maximum rotation speed of 600 rpm.
Options: Customizations include different ohmic values, tolerances, linearities, electrical travel, connectors, and protection class upgrades to IP 65. Mechanical and electrical references can also be customized.
