Installation Guide
- Mount the sensor head in downward, side, or upward position.
- Downward mounting gives 0.4 N measuring force.
- Side mounting gives 0.3 N measuring force.
- Upward mounting gives 0.2 N measuring force.
- Connect to GT2 amplifier using M8 connector.
- Keep operating temperature between -10 and +55 °C.
- Avoid freezing and condensation.
Debugging and Maintenance Convenience
- 2-colour LED shows red or green operation status.
- Absolute system means no tracking error after power loss.
- 1 ms sampling cycle supports fast inspection.
- 4 Hz mechanical response suits low-speed precision tasks.
- No built-in ports reduce setup complexity.
- M8 connector allows quick amplifier connection.
Compatibility Notes
