SD501201 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. Each Hall Effect sensor provides one square wave pulse for each tooth. 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 indicated by which channel leads the other.

Features
  • Immune to target run out
  • 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
