The latest 360-degree sealed noncontact rotary sensor from BEI Duncan Electronics is only 8mm thick.
The latest 360-degree sealed noncontact rotary sensor from BEI Duncan Electronics is only 8mm thick.
The ultra-thin NCAPS sensor has been developed to provide a cost effective, high resolution, rotary position sensor suitable for many markets including heavy equipment, oil field, medical instrumentation, factory automation and aerospace.
The ultra-thin module is fully tested and supplied as a packaged unit with sealed rotor and mating connector.
It is ideal for installation where there are tight packaging constraints.
NCAPS technology features true 360-degree absolute position feedback at speeds up to 18,000rev/min.
Using the phase shift principle, it is not sensitive to power supply voltage fluctuations.
As the sensor has only one moving (electrically passive) part it can be mounted directly on to the input shaft.
Its sealed design makes it particularly suitable for environments where particle contamination and high humidity would cause optical based sensors to lose reliability.
Three standard output formats are available, analogue, PWM (pulsewidth modulation) and dual triangle, which provide users with a choice of flexible electrical interfaces for different applications.
Sensors are supplied pre-programmed with the preferred option and other custom outputs are available to special order.
The ultra-thin NCAPS sensor is part of BEI's extensive range of non-contacting sensors that also include optical encoders and Hall effect sensors.
All provide reliable and accurate position sensing for a wide range of applications.
