Product Description P/N: GT2-PA12KL
Description
The KEYENCE GT2-PA12KL is a high-precision digital contact sensor head designed for accurate dimensional measurement and position verification in industrial automation systems. Featuring a 12 mm measuring range, 0.1 µm resolution, and low contact force, it is suitable for inspecting delicate workpieces and measuring small dimensional changes while minimizing the mechanical load applied to the target.

Information About GT2-PA12KL
The GT2-PA12KL is part of KEYENCE’s GT2 series of high-accuracy digital contact sensors and uses the Scale Shot System II absolute detection method to avoid tracking errors. Its air-cylinder mechanism operates with clean, dry air at a specified pressure range of 0.05 to 0.07 MPa, supporting consistent low-force contact measurement. The sensor provides an indicated accuracy of 1 µm peak-to-peak and a 4 ms sampling cycle for precision inspection tasks. It is intended for use with compatible GT2-series controller equipment, and the sensor head cable is optional and connects through a relay connector.
Key Feature:
-
12 mm Measuring Range: Supports contact-based dimensional inspection across a 12 mm measurement span.
-
0.1 µm Resolution: Detects very small measurement changes for fine inspection tasks.
-
1 µm Indicated Accuracy: Provides 1 µm peak-to-peak indicated accuracy under the manufacturer’s specified conditions.
-
Low Measuring Force: Applies approximately 0.4 N downward, 0.35 N sideways, or 0.3 N upward at the center of the range under the specified air pressure.
-
Absolute Detection System: Uses Scale Shot System II to avoid tracking errors during measurement.
-
Air-Cylinder Operation: Uses clean, dry air with an applied pressure range of 0.05–0.07 MPa.
-
Fast Sampling Cycle: Provides a 4 ms sampling cycle for responsive inspection and measurement.
-
Industrial Construction: Uses a SUS 303 main body case and a two-color red/green operation indicator.
The GT2-PA12KL delivers the reliability and precision required for low-force dimensional inspection, automated quality control, and repeatable measurement of sensitive components.
