Number of lines: 100 lines.
Outer diameter: 22mm.
Hole diameter: 3.5mm.
Thickness: 0.3mm.
Material: alloy steel.
Production process: laser cutting.
Supply voltage: 5V (3.3V is also available).
Wiring: Red 5V / Black GND.
Output signal: 5Vp-p two-phase signal output.
Two signal lines, one yellow, one blue.
Yellow and blue are two TTL level signals (can be directly connected microcontroller)
(Note: Measuring Reversible rely on these two levels to distinguish between forward or reverse).
