This is the section you need if you are standing at a control cabinet with a wire cutter in your hand.
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 | – | keyence gs-11pc manual

Before you power up your GS-11PC, verify these items from the manual:
Solution: Internal spring wear or contamination. The manual specifies a maintenance cycle: apply a drop of Keyence S-04 (light machine oil) to the spindle shaft every 100,000 cycles. Do not use WD-40. You will likely see two types of documents:
The Keyence GS-11PC is a high-accuracy, spring-loaded, digital displacement sensor head. It is part of Keyence’s legacy “GS” series, designed to be used with standalone display units like the Keyence RD-50 or LV-series controllers.
Unlike standard dial gauges (mechanical), the GS-11PC converts linear displacement (movement of the spindle) into an electronic digital signal. This allows PLCs (Programmable Logic Controllers) and data loggers to read thickness, warpage, or depth in real-time.

Why people lose the manual: The GS-11PC is often sold as a standalone head. Original documentation was a small folded sheet included in the box 10–20 years ago. The connector pinout is not printed on the device itself.
