The Keyence LR-W500 Cable Type Sensor is a highly adaptable reflective sensor designed to provide accurate and stable detection across a wide range of applications. Featuring a 2 m cable connection for secure installation, the LR-W500 combines cutting-edge optical design with robust environmental resistance, making it suitable for demanding industrial environments where reliability and precision are essential.

At the core of its design is a versatile detection range of 30 mm to 500 mm, supported by an adjustable spot diameter that automatically scales with distance. For example, the sensor projects a spot of approximately 3.5 mm at 100 mm, 9 mm at 250 mm, and 18 mm at 500 mm. This flexibility enables the LR-W500 to adapt to different target sizes and installation requirements without compromising accuracy. Combined with its white LED light source, the unit provides stable detection across a wide variety of surfaces and colors, including challenging materials like transparent plastics, shiny metals, or textured surfaces.

Speed and adaptability are further enhanced by the sensor’s selectable response times, ranging from ultra-fast 200 microseconds for high-speed production lines to longer delays of up to 500 ms for more stable readings. This versatility allows operators to fine-tune the LR-W500 to match the specific needs of their process, whether emphasizing precision, stability, or throughput. A built-in timer function with OFF-delay, ON-delay, and one-shot modes adds even more customization to detection behavior, preventing false triggers and enhancing reliability.

The sensor’s I/O options provide further operational flexibility. With selectable NPN or PNP open-collector outputs, the LR-W500 can easily integrate into a wide range of control systems. It also supports external input functions, including tuning and transmission OFF, simplifying setup and offering better adaptability in multi-sensor environments. In addition, the mutual interference reduction function allows up to two units to operate simultaneously with alternate frequencies, ensuring consistent detection even when multiple sensors are positioned close together.

Durability is another hallmark of the LR-W500. Its IP65/IP67-rated construction ensures resistance to dust, water, and environmental stress, while the zinc die-cast housing with nickel-chrome plating provides mechanical strength and protection against corrosion. The unit is also tested against vibration and shock resistance, tolerating forces up to 1,000 m/s² across all axes, guaranteeing performance in rugged environments. Designed with robust protective circuitry, the sensor resists reverse power connections, surges, and output overloads, further ensuring reliability and system safety.

Weighing approximately 170 g including its cable, the LR-W500 is compact yet rugged, offering long-term performance with minimal maintenance. Its combination of wide detection range, flexible operation, and durable construction makes it ideal for a variety of applications such as packaging inspection, assembly verification, object positioning, and quality assurance tasks.

In summary, the Keyence LR-W500 delivers an exceptional balance of speed, adaptability, and ruggedness. Its wide-range detection capability, combined with advanced LED technology and durable housing, makes it a versatile sensor solution for modern automation systems requiring both precision and resilience.
