Key Benefits

Transmit & Receive in One Unit — High transmit sensitivity of 107dB paired with -170dB receive sensitivity enables reliable detection across the full 15cm to 7m range
Automation-Ready 112kHz — Operating frequency chosen for compatibility with common industrial drive circuits and signal processing routines
Robotics Integration — Compact cylindrical form factor at 14g mounts easily in robotics frames; IP65 rating handles workshop dust and occasional washdown
800Vpp Drive Compatibility — Handles standard industrial drive levels (2% duty cycle tone burst) without requiring specialized high-voltage circuitry
Signal Processing Friendly — 1000pF capacitance and 420Ω resistance values align with typical microcontroller ADC and timer-based measurement approaches
