Honeywell SNG-S Speed Sensors use a magnetically biased Hall-effect IC to accurately sense the movement of ferrous metal targets. The IC and a permanent magnet are sealed in a rugged, probe-type package. Honeywell SNG-S Speed Sensors detect the alteration of the magnet’s flux density when it is approached by ferrous metal. A sensor positioned at the circumference of a revolving gear wheel detects the teeth and spaces and supplies a digital pulse output with a frequency proportional to gear wheel speed. Optimum performance depends on a combination of variables, such as target material, geometry/speed, sensor/target gap, and environmental temperature. The sensors offer an IP69K environmental rating, EMC radiated immunity protection, an O-ring seal, and a -40°C to +140°C operating temperature range.
Features:
- -40°C to +140°C operating temperature range
- Insensitive to orientation (angular rotation) during assembly
- Environmental sealing, moisture ingress protection rated to IP69K
- Robust electrical noise immunity, electrical noise radiated immunity (EMC) rated to 100V/m
- 0kHz to 15kHz zero speed detection, high-frequency switching capability
- O-ring seal enables environmental sealing to the mounting surface
- 4.5V to 24V or 4.5V to 8V to 24V supply voltage range
- CE certified
Applications:
- Transmission speed sensing in heavy-duty trucks, buses, agriculture, and construction machines
- Wheel speed detection in material handling, agriculture, and construction machines
- Motor speed sensing in vehicle powertrain and hybrid engines in heavy-duty trucks, buses, agriculture, and construction machines
