Pencil-Type Contact Sensor


Keyence Corporation of America introduces the GT2-P, the newest edition to the high-precision GT2 Series of contact sensors. The GT2-P features High Accuracy Measurement, a Tough & Rugged Design, and Flexible Communication Options all combined into a body the size of a pencil.

High Accuracy The GT2-P uses Keyence's own Scale Shot System in order to achieve the highest accuracy in its class. The Scale Shot System combines both the conventional scale and transformer methods in order to achieve high accuracy throughout its entire range while also maintaining absolute positioning. The GT2-P achieves an accuracy of 1 µm, or 0.04 thou.  

Tough & Rugged The GT2-P was designed for extended use, even in harsh environments, which other contact sensors would not be able to withstand. Thanks to the innovative use of long-lasting linear ball bearings, the GT2-P has a detecting durability up to 100 million cycles, all while maintaining an IP-67G enclosure rating. This means the GT2-P is not only resistant to water, but to oils as well, greatly expanding its versatility.   Flexible Communication Multi-sensor applications can easily be set up thanks to flexible amplifier and communication lineups. Up to 5 GT2-P heads can be connected to a single amplifier, while up to 3 amplifiers can be connected to create a system of 15 cooperating heads. Communication units can then be used to send data over RS-232, Ethernet/IP, Profinet, Profibus, and DeviceNet, among other various communication protocols.
