KEYENCE Expands GT Series Contact Sensor Lineup to Empower High-Precision Industrial Measurement
OSAKA, Japan – July 8, 2026 – KEYENCE Corporation, a global leader in industrial automation and sensing technology, has further optimized its flagship GT series general-purpose digital contact sensors, launching a comprehensive portfolio including GT-H22L, GT-H10L, GT-H10, GTB2S-N13, GT-75A, GT-72A, GT-71AP, GT-71A and GT2-H32 models. The upgraded product lineup delivers ultra-high precision, stable durability and diverse structural designs, fully meeting the escalating demands of modern manufacturing for micron-level dimensional inspection, displacement detection and quality control across multiple industries.
As a core series of KEYENCE’s contact measurement sensors, the GT series adopts the mature Scale Shot System II detection technology, featuring absolute value measurement without tracking errors, which ensures long-term consistent and accurate data output even in high-frequency continuous operation scenarios. The newly supplemented and optimized models cover low-stress sensor heads, standard detection units, high-performance amplifier modules and upgraded GT2 series enhanced sensors, forming a complete measurement solution that integrates sensing, signal processing and data output.
In terms of sensor head configuration, the GT-H10 and GT-H10L are designed for compact and low-measurement-force scenarios. The GT-H10L low-stress model effectively avoids surface damage to ultra-thin, soft and precision workpieces such as electronic components and plastic parts, while maintaining a stable 10mm measurement stroke. The GT-H22L extends the measurement range with a 22mm stroke, balancing wide-range detection and high precision, perfectly adapting to dimensional tolerance detection of medium and large mechanical parts. As an upgraded iteration, the GT2-H32 sensor head achieves breakthroughs in detection stability and environmental adaptability, with enhanced dustproof, anti-vibration and temperature resistance performance, suitable for harsh industrial production environments including automotive manufacturing and mechanical processing workshops.
The amplifier module series, including GT-71A, GT-71AP, GT-72A and GT-75A, constitutes the core signal processing unit of the GT sensor system. The base-model GT-71A supports high-speed signal acquisition and standard NPN/PNP signal output, compatible with most industrial PLC and automation control systems. The GT-71AP adds advanced parameter calibration and data storage functions, enabling on-site fine-tuning of measurement accuracy and batch data recording. The GT-72A optimizes response speed, realizing microsecond-level rapid signal feedback for high-speed production line detection. The high-endGT-75A integrates multi-channel synchronous processing technology, supporting simultaneous access of multiple sensor heads, greatly improving the efficiency of multi-point synchronous detection in automated production lines.
Complementing the core lineup is the GTB2S-N13 compact integrated sensor unit, which features an ultra-miniature structure and simplified installation design. It is specially developed for narrow-space installation scenarios such as precision assembly equipment, semiconductor testing devices and micro-electromechanical systems, achieving flexible and efficient high-precision detection in limited installation space, filling the gap of compact high-performance contact measurement in micro-manufacturing scenarios.
Featuring unified high-precision measurement capability, diverse structural forms and strong environmental adaptability, the full range of updated KEYENCE GT series sensors is widely applicable to key industrial fields including 3C electronic product testing, automotive parts precision inspection, aerospace component dimensional calibration, new energy equipment manufacturing and precision mold detection. Compared with traditional contact sensors, the new lineup effectively reduces measurement errors, lowers equipment maintenance costs, and improves the overall stability and automation level of production line quality inspection.
Industry analysts pointed out that with the continuous upgrading of global intelligent manufacturing, the demand for high-precision, high-stability and scenario-adaptive detection equipment is increasing day by day. KEYENCE’s iterative upgrade and full-line optimization of the GT series contact sensors will provide more reliable and flexible measurement solutions for precision manufacturing enterprises worldwide, helping the industry achieve higher-standard quality control and efficient production upgrading.
KEYENCE stated that it will continue to focus on the pain points of industrial precision detection, continuously iterate sensor hardware performance and intelligent algorithm functions, and expand the application boundary of high-precision sensing technology to empower the high-quality development of global intelligent manufacturing.
