Basic Rotary Position Sensor Type 1

This rotary sensor is 25mm diameter and measures absolute the angle of a target at up to 5mm gap. Used in conjunction with a CTU chip, the system reports full absolute angular position over 360°.

• Simple non-contact target
• Sensor coil pattern < 25mm dia.
• Full absolute sensing over 360°
• Operates up to 5mm gap
• Standard 4-layer PCB process
• Highly repeatable

Performance

• ±0.5° (±0.14%) Absolute Error at gap 1.5mm
• ±1° at Radial Misalignment 1mm, gap 0.5…2.5mm
• <±0.18° change (±0.05%) across temperature -40°C…85°C, ≤ 3.5mm Gap

The CTU Development Kit includes one 25mm rotary sensor.
