KD-5600 Digital Differential Measuring System

High-resolution eddy current system with digital and analog configurations for high-speed, noise-free displacement measurements.


Key features

  • 24-bit resolution and high sampling rate
  • Multiple output configurations (SPI, analog, FPGA)
  • High linearity and low noise
  • Bandwidth adjustable up to 60 kHz
  • Includes calibration file with resolution & linearity
  • Designed for embedded or high-speed systems

Performance highlights

The KD-5600 system from Kaman is engineered for precision displacement and position measurements using a differential eddy current technique. With 24-bit resolution and a sampling rate up to 128 kHz, it offers superior signal clarity and responsiveness. It utilizes matched sensor pairs and digital filtering for enhanced stability and minimal noise.

Usage conditions

The system is ideal for applications that demand high bandwidth, linearity, and low-noise signal transmission. Powered by 8–28 VDC, it offers SPI output or analog signals depending on the model.

Possible applications

  • Fast steering mirrors
  • Magnetic bearing control
  • Shaft vibration monitoring
  • Image stabilization systems
  • Adaptive optics and aerospace actuators

Advantages of choosing this product

The KD-5600 system stands out due to its true digital output, high bandwidth capabilities, and low-noise operation. Designed with engineers in mind, the system offers flexibility in connectivity (digital, analog, or FPGA interfaces) and delivers calibrated, high-accuracy measurements. It is especially suited for high-performance motion control and vibration analysis in aerospace, defense, and precision manufacturing.

Other important features

  • High-end communication via SPI or FPGA
  • Output up to 48-bit data at 128kHz (KD-5690)
  • No firmware required (FPGA model)
  • Easy integration with embedded systems
  • Compact system design with 9-pin connector
