Description

The KMXP1000 utilizes an anisotropic magnetoresistive (AMR) sensing principle to provide non-contact, linear position feedback. Its Wheatstone bridge configuration outputs a differential analog voltage proportional to the position of a moving magnet within a 1 mm air gap, offering superior resolution and stability compared to Hall-effect or inductive sensors.

Engineered for reliability in demanding applications, the sensor features a compact, leadless DFN-12 surface-mount package that withstands high temperatures, contaminants, and electromagnetic interference. Its design supports automated tape-and-reel assembly and offers flexible soldering orientations for streamlined integration into industrial PCBs and control modules.

Key Features

  • High-Precision AMR Technology: Delivers linear position sensing with accuracy up to 10 µm and excellent long-term stability.
  • Wide Operating Temperature: Functions reliably across an extended range from –40°C to +150°C.
  • Robust Environmental Protection: Resistant to oil, dirt, dust, and other industrial contaminants.
  • EMC-Proof Design: Enhanced noise immunity ensures stable signal output in electrically noisy environments.

Frequently Asked Questions

What is the output signal type and range of the KMXP1000 sensor?

The KMXP1000 provides an analog voltage output proportional to position, with a sensitivity of 18 to 26 mV per volt of supply (mV/V). For a standard 10V supply, this translates to a full-scale output swing of approximately 180 to 260 mV across the 1 mm measurement range, suitable for direct connection to a high-resolution ADC.

What are the key mounting and integration considerations for the DFN-12 package?

The compact DFN-12 package requires precise PCB pad design and reflow soldering. It supports both flat and perpendicular soldering orientations. Ensure proper thermal relief and follow recommended reflow profiles to avoid thermal stress. The sensing direction is along the package's long axis, and the target magnet must be aligned within the specified 1 mm air gap.

How does the AMR technology in this sensor compare to a standard Hall-effect sensor?

Anisotropic Magnetoresistive (AMR) technology offers significantly higher precision and stability over temperature compared to Hall-effect sensors. The KMXP1000 achieves sub-50 µm accuracy and superior linearity within its 1 mm range, making it ideal for applications where Hall-effect sensors lack the necessary resolution or long-term drift performance.

What is the recommended magnet specification for use with this sensor?

For optimal performance, use a permanent magnet with a strong, stable magnetic field. Refer to the official TE Connectivity datasheet for specific magnet size, grade (e.g., N52 NdFeB), and polarization requirements. The magnet must move linearly within the 1 mm air gap, and its field strength should be sufficient to drive the AMR bridge to full output without saturation.
