The Keyence LK-G3001 Separate Controller (NPN Output) is a high-performance measurement controller designed to maximize the precision and flexibility of LK-G series sensor heads. Engineered for demanding industrial applications, it delivers ultra-high resolution, robust connectivity, and advanced data processing capabilities that ensure reliable results in quality control, inspection, and automation systems.

One of the core strengths of the LK-G3001 is its precision measurement capability. With a minimum display resolution of 0.01 µm and a selectable display range from ±9,999.99 µm to ±9,999.99 mm, the controller is versatile enough to handle both micro-scale inspections and larger displacement measurements. The refresh rate of 10 times per second ensures real-time monitoring and stable output, supporting consistent process control.

The controller also supports dual sensor head connectivity, allowing up to two LK-G sensor heads to be connected simultaneously. This capability enables operators to perform multi-point measurement, thickness evaluation, or differential inspection within a single system, reducing hardware requirements while improving operational efficiency.

Connectivity is another key feature of the LK-G3001. It offers a broad range of output options, including dual analog voltage outputs (±10 V), dual current outputs (4–20 mA), and NPN open-collector outputs for comparator and alarm functions. For digital integration, the controller supports binary output (21-bit measured data), strobe output, and RS-232C communication with baud rates up to 115,200 bps. A USB 2.0 interface ensures compatibility with modern systems, while program switching and laser control inputs provide additional operational flexibility.

The LK-G3001 is built with a range of advanced processing functions to ensure accuracy and usability. Features such as auto-zero, calibration, averaging, and filtering maintain measurement stability even in noisy environments. It also includes mutual interference prevention for stable operation when multiple units are used in close proximity. With 8-program memory storage, operators can quickly recall optimized settings for different applications, minimizing setup time. Additional functions such as ECO mode, ABLE tuning, target setting, transparent surface measurement, and statistical processing make the controller a powerful tool for diverse inspection tasks.

Engineered for industrial reliability, the LK-G3001 is compact yet durable. Operating on 24 VDC ±10% power supply with a current consumption of up to 600 mA (with two heads), it ensures efficient power use. The unit performs reliably in ambient temperatures from 0 to +50 °C and humidity levels from 35 to 85% RH (non-condensing). At approximately 370 g, it is lightweight and easy to integrate into machine setups.

In summary, the Keyence LK-G3001 Separate Controller combines ultra-precise measurement capability, dual-sensor support, flexible output options, and advanced processing functions into a compact, reliable unit. It is the ideal choice for manufacturers seeking high-accuracy, multi-functional, and future-ready solutions for industrial measurement and quality assurance.
