The GS-11PC uses a 11-pin metal circular connector (Hirose type) . The manual lists the following pin assignments (standard for most Keyence GS sensors):
| Pin No. | Signal Name | Description | Wire Color (Typical) | | :--- | :--- | :--- | :--- | | 1 | A Phase | Output signal A (0° phase) | White | | 2 | B Phase | Output signal B (90° phase) | Blue | | 3 | +5V | Power supply (Stabilized 5V DC) | Red | | 4 | GND | Common ground (0V) | Black | | 5 | Shield | Cable shield / Frame ground | Bare wire | | 6 | Z Phase (Origin) | Zero/Index pulse (once per revolution) | Orange | | 7 | NC | Not connected | – | | 8 | NC | Not connected | – | | 9 | NC | Not connected | – | | 10 | NC | Not connected | – | | 11 | NC | Not connected | – |
Crucial notes from the manual:
Here are three real-world issues that the manual directly resolves:
Problem: The reading drifts by 5µm over an hour.
Problem: The gauge works, then dies when the motor starts.
