The Keyence PS-202 is an environment-resistant transmissive (thrubeam) sensor head designed for reliable performance in precision detection applications. Incorporating a robust protective design, advanced optical performance, and lightweight construction, the PS-202 is an ideal solution for industries requiring accurate and stable object detection under demanding conditions.

One of the key advantages of the PS-202 is its long-range detection capability. In TURBO mode, the sensor can reliably detect targets at distances up to 1,000 mm, while in FINE mode it operates effectively up to 500 mm. This flexibility allows the unit to be used across a wide variety of setups, from short-range detection tasks requiring precision to longer-range applications where extended reach is necessary. The use of an infrared LED as the light source ensures consistent performance with high reliability, even in environments where visible light interference may be present.

The PS-202 is also capable of detecting very small objects with high precision. In TURBO mode, it can detect objects as small as 0.5 mm in diameter, ensuring suitability for applications involving miniature components or fine materials. This makes it particularly valuable in fields such as electronics assembly, semiconductor processing, or quality inspection, where detecting fine irregularities is critical to maintaining product standards.

Durability and resistance to environmental conditions are major strengths of the PS-202. Its Teflon®-sheathed construction and IP67-rated enclosure provide strong protection against dust and water ingress, allowing it to operate reliably in harsh environments. It is designed to withstand ambient temperatures ranging from -10 to +60 °C, as well as relative humidity levels between 35 and 85% without condensation. This ensures stable and long-term performance even in facilities where temperature fluctuations or humidity could otherwise affect sensor operation.

Despite its rugged construction, the PS-202 remains compact and lightweight, weighing approximately 40 g including its integrated 2-meter cable. This small form factor simplifies installation and integration into automated systems, particularly in space-constrained environments. Its lightweight build also minimizes mechanical strain on mounting structures, ensuring secure and stable installation.

Overall, the Keyence PS-202 is a versatile and reliable transmissive sensor head built for precision detection under challenging industrial conditions. With its long-range thrubeam detection, ability to sense very small objects, environmental resistance, and compact design, it provides an excellent balance of performance and durability. Whether used in electronics, packaging, or general manufacturing, the PS-202 ensures accurate and stable detection, helping improve quality control and production efficiency.
