The Keyence LK-G87 sensor head is a precision-engineered measurement solution designed for multi-purpose applications that demand both accuracy and flexibility. Featuring a wide beam laser system, the LK-G87 supports two key measurement modes: diffused reflection and specular reflection. With a reference distance of 80 mm for diffused reflection and 75.2 mm for specular reflection, the sensor provides adaptability to different target surface conditions, whether matte or highly reflective. This versatility allows the LK-G87 to be deployed across a wide range of industries, from electronics and automotive to precision machining and quality inspection.

The measuring range of ±15 mm for diffused reflection and ±14 mm for specular reflection ensures that the sensor can handle slight variations in positioning while maintaining consistent performance. Its linearity of ±0.05% of full scale is a testament to its exceptional accuracy, making it ideal for applications that require detailed dimensional analysis, profile measurement, and high-precision surface evaluation. This high level of reliability is particularly beneficial in automated production lines, where even minor deviations can affect product quality.

At the core of the LK-G87 is a red semiconductor laser operating at 655 nm. With an output power of 0.95 mW, the laser is classified as Class II under both FDA CDRH and international standards, ensuring a safe yet powerful measurement beam. The visible red light facilitates alignment and setup while providing operators with clear feedback during operation. The beam produces a finely shaped spot size of approximately 70 × 1,100 µm, optimized for wide beam coverage while still maintaining precision. This design allows for the detection of surface irregularities and dimensional shifts that might be overlooked by conventional point-based sensors.

The LK-G87 is engineered for environments where durability, repeatability, and integration are crucial. Its advanced optical design minimizes measurement errors caused by surface characteristics, allowing stable detection across different materials such as metals, plastics, and coated surfaces. In applications involving high-speed manufacturing or automated inspection, the sensor’s responsiveness and accuracy ensure efficient quality control without slowing down operations.

In addition to its technical capabilities, the LK-G87 offers ease of use through seamless compatibility with Keyence’s LK-G5000 series controllers. This pairing provides advanced data processing, real-time monitoring, and system adaptability, giving users the tools to optimize measurement performance. Whether applied to machine tool positioning, assembly verification, or surface inspection, the LK-G87 consistently delivers reliable results.

In summary, the Keyence LK-G87 combines wide-beam versatility, ultra-high precision, and user-friendly operation in a compact sensor head. Its ability to adapt to different reflection modes, maintain exceptional linearity, and ensure safe, efficient measurement makes it a highly valuable component for precision-driven industries.
