Next-Generation Linear Position Sensing.

MEV Elektronik presents CambridgeIC’s innovative new range of resonant inductive Linear Sensors Type B. These sensors combine robustness, precision, reliability, and low cost, thanks to their manufacture using a conventional PCB process.

The new Linear Sensors Type B incorporate special coil designs from CambridgeIC. Currently available designs support measuring lengths of 40 mm, 50 mm, 100 mm, and 200 mm. Each sensor includes an excitation coil to energize the target, coarse sensor coils to establish absolute position, and fine sensor coils for precision and accuracy.

Efficient and Flexible Manufacturing

A key benefit of this design is that customers can manufacture the sensors themselves using design data provided by CambridgeIC. This approach helps to reduce production costs while maintaining full control over manufacturing.

The sensors detect the position of a moving, contactless target, which is also realised as a PCB comprising a resonant circuit with a printed coil and capacitor(s). This resonant target design generates substantially stronger signals than conventional inductive sensors, enabling high resolution, superior accuracy, wide operating gaps, and calibration-free operation.

Advanced Signal Processing with CAM622

The signal processing of the Linear Sensors Type B is handled by CambridgeIC’s CAM622 Resonant Inductive Position Encoder IC. The CAM622 provides:

SPI interface, delivering typically 1 μm noise-free resolution and full absolute position
Quadrature ABN interface, configurable down to 2 μm AB edge resolution
Newly announced BiSS-C interface support (BiSS is a trademark of iC-Haus GmbH).

With these features, CambridgeIC’s Linear Sensors Type B offer the speed and resolution of other encoders, but at a lower cost and with greater robustness and environmental immunity. Installation is straightforward, requiring only normal engineering tolerances and no special alignment.

Advantages over Magnetic Encoders

In contrast to magnetic linear encoders, the new Linear Sensors Type B provide absolute position feedback at power-on, operate with narrow track widths, and do not attract magnetic swarf, ensuring reliable operation even in challenging industrial environments.

Key applications

High-speed closed-loop motion control
Linear motor feedback and commutation
Valve position sensing
Steering rack position sensing in vehicles
Replacement of optical and magnetic position encoders

Evaluation Tools and Accessories

To support evaluation and development, CambridgeIC offers a comprehensive range of accessories:

CAM622 MultiComms Board: including the CAM622 processor and supporting SPI, BiSS-C, SENT, and quadrature ABN interfaces.
MultiComms Adapter: connects to a PC over USB and to a CAM622 via SPI, BiSS-C, or SENT. It allows PC-based operation of CambridgeIC CAM622 software for measurements and configuration of quadrature ABN and BiSS-C interfaces.
MultiComms Bundle: includes both the MultiComms Board and Adapter.

For evaluation purposes, MEV Elektronik offers sample sensors, targets, connecting cables, and MultiComms Bundles directly.
