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
