MEV introduces the Conntek KTH7111 and KTH7112 encoder ICs. Both devices set new standards in precision and ease of integration thanks to patented Automatic Non-Linear Calibration (ANLC) technology, which automatically compensates for mounting and magnet variations, ensuring exceptionally high accuracy.

Precision redefined: ANLC – Automatic Non-Linear Calibration

The ANLC feature is the heart of Conntek’s new encoder generation. While traditional magnetic angle sensors require external calibration procedures or host-side computation, the KTH7111 and KTH7112 perform the compensation fully automatically within the sensor.

KTH7111 supports off-axis topology, while KTH7112 is optimized for on-axis applications.

• Automatic measurement and error correction: The module records 16 measuring points over a complete revolution, determines deviations in the magnetic field line and calculates compensation parameters internally.
• No external calculation or firmware routines required: all analysis and storage are done on-chip.
• Outstanding accuracy after calibration achieving INL < ±0.1° (KTH7112) and INL < ±0.2° (KTH7111).
• Calibration status display via PWM signal (50% = calibration, high = successful, low = failed attempt).

This makes the installation of magnetic encoder systems significantly easier, more robust and more precise – even with mechanical tolerances or off-axis mounting.

Additional Highlights

• Ultra-low output noise (0.015° rms)
• Supports ABZ incremental output up to 16,384 steps/rev
• UVW commutation for 1–32 pole pairs (BLDC compatible)
• Configurable PWM frequency (120 Hz – 3.8 kHz)
• Flexible interface configuration via SPI and MODE pins
• On-axis and off-axis magnet compatibility

Benefits for System Designers

Thanks to the integrated ANLC feature, both encoders dramatically simplify production and calibration workflows while improving accuracy and robustness.

• Automatic and precise alignment compensation
• No external calibration hardware or software required
• Reduced assembly tolerance demands and manufacturing cost
• Consistent accuracy across temperature, voltage, and aging
• Optimized for motor control and robotics applications

Expert Insight

“With ANLC, Conntek brings real intelligence into hall-magnetic sensing,” says Guido Gandolfo, Product Line Manager at MEV. “The KTH7111 and KTH7112 eliminate the need for external calibration hardware or complex software routines — the sensor simply calibrates itself. This not only improves precision but also saves valuable development and production time for our customers.”

The KTH7801 is a high-performance 16-bit angle sensor IC for industrial, consumer and automotive applications.

KTH7801 combines high precision with exceptional compatibility and is designed as a direct replacement for commercially available angle sensor ICs – without any adaptations to existing systems.

Highlights of KTH7801:

• Drop-in compatibility: Mechanically and electrically compatible with competitive products.
• Optimized signal quality: High linearity (INL < ± 0.35°) for precise measurements.
• Suitable for industrial and automotive: Operating temperature range from -40 °C to +125 °C.
• Easy replacement: No redesign of the circuit board necessary.

With its compact dimensions, numerous interfaces, and affordable price, KTH7801 is ideally suited for many angle sensor applications. Thanks to its pinout, KTH7801 easily integrates into circuits that previously used established components.

“With the KTH7801, we are addressing the growing demand for reliable replacement components for existing industrial applications. The component was specifically designed to be easily integrated into existing designs and, in addition to its low price, even deliver improved performance,” explains Guido Gandolfo, Product Line Manager at MEV.

The KTH7801  is available now and is particularly suitable for customers who need to improve existing systems, reduce prices or respond flexibly to supply bottlenecks – without compromising on functionality or quality.

The Evalkit EVM7801 is available from MEV for evaluation.
