Rotational speed and direction sensor SDX01201 Series

Hall effectIP67

SD101201 Sensors Description Has two Hall Effect sensors; one detects speed and the other detects direction of movement of gear teeth. The outputs are open collector transistors. The Speed output goes high (on) when sensing the leading edge of a tooth and low (off) on the trailing edge of the tooth when run against a standard target. The direction of movement is latched on the leading edge of the speed sensor; the Direction output goes high for clockwise rotation and low for counterclockwise rotation. The state of the Direction output always leads the rising edge of the speed output Features Separate digital outputs for speed and direction From near zero speed up to 15 kHz sensing capability Plastic flange-mount sensor rated to 125 ⁰C RoHS compliant IP67 Typical air gap of 1.5 mm (0.06”)* Typical Applications Wheel speed and direction Hoist speed and direction Transmission speed and direction Industrial feedback and control Environmental Specifications Vibration Sinusoidal, 3.3 g max from 20 Hz to 1 kHz Maximum Speed Detection 15 kHz Operating Temperature -40 ⁰C to 125 ⁰C (-40 ⁰F to 257 ⁰F) Storage Temperature -40 ⁰C to 125 ⁰C (-40 ⁰F to 257 ⁰F) Ingress Protection IP67 Electrical Specifications Operating Supply Voltage 4.75 to 24 VDC Maximum Input Voltage 30 VDC Maximum Reverse Voltage 30 VDC Supply Current 20 mA max Output Sink Current 20 mA max Typical Operating Time 5 μs Recommended Pull-Up Resistor See chart
