Keyence GT2-P12F Stylus Digital Contact Sensor 12 mm 0.5 μm IP67G

SKU CH-QCKY-PF4SS MPN GT2-P12F

A digital contact sensor with a 12 mm range, 0.5 μm resolution and IP67G protection for harsh environments

  • TypeSensors
  • 12 mm measuring range with 0.5 μm resolution
  • IP67G and IP67 enclosure ratings protect against dust and water
  • NEMA Type 13 rating adds oil and coolant resistance
  • Operates from -10 °C to +55 °C without freezing
  • Withstands 1,000 m/s² shock and 1.5 mm vibration at 55 Hz

High-Accuracy Digital Contact Sensor

The Keyence GT2-P12F is a stylus-type digital contact sensor built for precision measurement tasks. It suits quality-control engineers and automation integrators who need reliable dimensional data in industrial environments. The sensor delivers a measuring range of 12 mm with a resolution of 0.5 μm. It is not intended for non-contact applications or for ranges beyond the stated 12 mm.

Environmental Limits and Protection

The enclosure meets IP67G per JIS, IP67 per IEC and NEMA Type 13 ratings for dust and water resistance. Operating temperature spans -10 to +55 °C with no freezing, while humidity tolerance is 35 to 85 % RH with no condensation. Vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude for 2 hours in each axis, and shock resistance is rated at 1,000 m/s2 per IEC 60068-2-27. Buyers needing higher temperature or immersion specs must look elsewhere.

Resolution Determines Suitability

The single specification that decides fit is the 0.5 μm resolution, which sets the finest detectable displacement. This figure governs whether the sensor meets the tolerance requirements of a given inspection routine. If the process demands finer resolution, this model will not satisfy it. The 12 mm range and environmental ratings support the deployment, but resolution remains the decisive parameter.

Questions about this item

What does the 12 mm measuring range cover for the GT2-P12F?

The sensor captures linear displacement across a 12 mm span, so any feature that fits within that travel can be measured in a single stroke.

What does 0.5 μm resolution mean on the shop floor?

The GT2-P12F can detect position changes as small as half a micron, letting you verify tight tolerances without averaging multiple readings.

How do the IP67G and NEMA 13 ratings limit where I can mount this sensor?

IP67G (JIS) and IP67 (IEC) plus NEMA Type 13 mean the housing withstands oil, coolant splash and temporary immersion, so it survives typical machine-tool environments.
