Miniature Through Hole

This range of rotary sensors is for angle measurement over a full 360° of rotation.  Sensors and targets both include central holes that allow a shaft to pass through them, and have a balanced design for immunity to misalignment.

Features

• Full absolute sensing over 360°
• Sensors...
  • Built using conventional PCB fabrication
  • Assembled sensors available from CambridgeIC
  • Blueprints available for customers to build sensors themselves
  • Connect to Type 4 circuitry - up to 2 sensors per CAM204 chip
  • Also functions with Type 1 circuitry if 3 or 4 sensors per CAM204 chip are needed
• Targets...
  • Base built using conventional 1-layer PCBs
  • SMD transponder coils mounted to PCB in balanced configuration for immunity to misalignment
  • SMD capacitor(s) to complete resonant circuit
  • Buy from CambridgeIC or build from components
• Holes in sensors and targets e.g. for through shaft
• Repeatable across time and temperature

Applications

• NEMA8 stepper motor position feedback
• Actuator position feedback
• Motion control
• Valve position sensing
• Absolute optical encoder replacement
