Capacitive Proximity Detection System: - High Signal to Noise Ratio (SNR) - Adjustable sensitivity - Noise Rejection Filters - Scanning method actively optimized to attenuate strongest noise frequencies - Automatic calibration with optional user presets - Dynamic threshold management adjusts sensitivity of sensor based on the level of environmental noise - Constant press calibration tracks the expected offset when the sensor is pressed and adjusts the threshold to automatically achiev.

MTCH112
Dual-Channel Proximity/Touch Controller
Features:
• Capacitive Proximity Detection System: - High Signal to Noise Ratio (SNR) - Adjustable sensitivity - Noise Rejection Filters - Scanning method actively optimized to attenuate strongest noise frequencies - Automatic calibration with optional user presets - Dynamic threshold management adjusts sensitivity of sensor based on the level of environmental noise - Constant press calibration tracks the expected offset when the sensor is pressed and adjusts the threshold to automatically achieve the best press/release behavior - User-defined “minimum shift” values specify the lowest amount of signal change to activate a state transition. Automatic thresholds never decrease below these settings.
