GT2-A12 Keyence Digital Contact Sensor Head – Air Push Type, 12 mm Stroke
GT2-A12 is a high-accuracy digital contact sensor head from the Keyence GT2 series. It uses the Scale Shot System with absolute detection. This design avoids tracking error. The sensor head suits precision positioning and inline measurement. It connects to a GT2 series amplifier through an M8 connector. The air push type supports stable operation in automated fixtures.
The 12 mm measuring range and 0.5 µm resolution support fine measurement tasks. The 2 µm indicated accuracy helps maintain repeatable results. The 1 ms sampling cycle supports fast production cycles. The IP67 protection rating allows use in harsh industrial environments. The GT2-A12 is active and confirmed by Keyence as of 2026-09.
