Cherry has launched a geartooth speed sensor, GS102301, which is suitable for applications that need strong, dependable and quick sensing. The hall-effect speed sensor has been tested to SAE J1455.
Geartooth Speed Sensor Survives Harsh Environments
The sensor has the ability to self-adjust on different magnetic flux densities; hence there is no need to optimize the position of the sensor within a small operating range of the magnetic flux.
The single hall plate design of GS102301 sensor will not be affected by alignment issues, enabling several mounting options. The new speed sensor is an inclusion in the company's near-zero speed sensors that operate in a temperature range of -40°C to 140°C. The sensor complies with IEC60529 IP68 standards required for water immersion.
The circuitry of the speed sensor protects it from ESD and EMI. The circuitry is also reverse battery protected. The GS102301 digital output speed sensor needs a minimum of 3 mA input for a proper function. With a straight, threaded housing, and 2.8-inch length, the sensor can be fitted into a standard o-ring port. The geartooth sensor has the ability to withstand installation torque of up to 15 ft lbs.
