KEYENCE GT2-P12F High-precision, absolute contact digital displacement sensor

Product Description: KEYENCE GT2-P12F

The KEYENCE GT2-P12F is a high-precision, contact-type digital displacement sensor designed for industrial applications requiring accurate dimensional measurement in harsh environments. It employs a scale pulse system II with an absolute type design (no tracking error) to ensure reliable performance. The sensor is ideal for precision tasks such as machine tool control, quality inspection, and deformation monitoring.

Precision measurement in metalworking (e.g., component inner/outer diameter checks).

Quality Assurance:

Dimensional inspection of smartphone casings, LCD panels, and battery components.

Deformation analysis of frames and stamped parts.

Process Monitoring:

Height control in polishers, roll gap adjustment in rolling mills.

Notes

Installation Guidance:

Ensure proper alignment and secure mounting to avoid measurement errors.

Use the specified cables (e.g., M8 oil-resistant cables) for IP67 compatibility.

Environmental Considerations:

Avoid extreme temperatures or humidity beyond the rated range.

Clean the sensor head regularly to prevent dust/oil buildup.

Calibration:

Verify accuracy periodically, especially in environments with temperature fluctuations.
