Noncontacting Rotary Sensor

Miniature noncontact sensors are designed for dependability and precision in small and harsh environments.

The RSC 1300 Series are based on vertical Hall technology with a cross structure that is affixed to a silicon chip that provides 360° measurements with 10-bit resolution. Maximum rotating speed is 10,000 rpm with a sample rate of 10 MHz. Linearity is to ±0.3% and repeatability to 0.1% of signal range. Available options include analog, incremental, SPI, SSI, and PWM outputs; custom shaft designs; and customer-specific cabling.
