Available. The Keyence GT2-71MCP is a high-accuracy digital contact sensor amplifier unit designed for precise measurement applications. This main unit features a PNP output and is intended for DIN-rail mounting, ensuring secure and stable installation in industrial settings. Operating within a power supply voltage range of 20 to 30 VDC, it offers two power consumption modes: a normal mode with a maximum of 2,700 mW (90 mA at 30 V) and an eco mode with a maximum of 2,200 mW (73.3 mA at 30 V), facilitating energy efficiency. The device is equipped with a 6.5-digit 7-segment LED display for measured values, with a range from -199,999.9 to 199,999.9 and a resolution of 0.1 μm, providing clear and precise readings. Additionally, it includes a two-color, 13-level bar LED display and various indicators for enhanced user interface. The GT2-71MCP supports control inputs such as timing, preset, reset, and bank inputs, all utilizing no-voltage inputs. For control outputs, it offers PNP open collector outputs (HH/HI/GO/LO/LL) with a maximum current of 50 mA and a residual voltage of 1 V or less. The analog output is a 4 to 20 mA signal with a maximum load resistance of 350 Ω, and the response time can be set to various intervals, including 3 ms, 5 ms, 10 ms, 100 ms, 500 ms, and 1,000 ms, depending on the application requirements. Designed to operate in ambient temperatures ranging from -10 to +50 °C (with a reduced range of -10 to +45 °C when expansion units are connected) and relative humidity between 35% and 85% (non-condensing), the GT2-71MCP is built to withstand diverse industrial environments. Its vibration resistance is rated for 10 to 55 Hz with a double amplitude of 1.5 mm, tested for 2 hours in each of the X, Y, and Z directions, ensuring durability and reliability. The main body case is constructed from polycarbonate, the key top from polyacetal, the front sheet from PET, and the cable from PVC, combining strength and flexibility. With an approximate weight of 70 g, the GT2-71MCP is a robust and efficient solution for high-precision measurement tasks in industrial automation.
