This air-cylinder model employs a quartz glass scale for superior stability and repeatability while maintaining a compact, durable structure. Its IP67-rated zinc die-cast housing and 1 MPa pressure resistance make it suitable for pressurized or contaminated environments. The sensor’s 1 ms sampling cycle and 0.5 µm resolution enable real-time, high-precision measurements in manufacturing, assembly, and quality control systems. Key Features: Wide Measurement Range: Capable of precise displacement measurement up to 50 mm (1.97"). Exceptional Resolution: Achieves 0.5 µm (0.02 mil) resolution for fine measurement tasks. High Indicated Accuracy: Maintains ±3.5 µm (0.14 mil) repeatable precision under industrial conditions. Air Cylinder Integration: Designed for pneumatic mounting applications with 0.25–0.5 MPa pressure range. Durable Build: Features a zinc die-cast main body and aluminum cylinder for long-term stability. Environmental Protection: Rated IP67, resistant to water, oil, and dust for harsh factory environments. Fast Sampling: 1 ms response ensures rapid feedback for automation and inspection systems. High Shock Resistance: Tolerates vibration (10–55 Hz) and repeated contact cycles without performance loss. Stainless-Steel Contact Tip: Constructed from Type 304/440C stainless steel for extended durability. Dual-Color LED Indicator: Integrated red/green LED simplifies operational status monitoring. The GT2-A50 delivers the precision, speed, and ruggedness required for pneumatic displacement measurement, inspection automation, and process feedback applications.
