The Keyence PS-201C is a high-performance transmissive sensor head engineered for long-distance detection in demanding industrial environments. Its robust design combines precision sensing with environmental resistance, making it suitable for manufacturing lines, packaging systems, and automated material handling operations.

Built as a thrubeam sensor, the PS-201C provides reliable long-range detection with two selectable operating modes. In TURBO mode, it achieves a maximum detecting distance of 4,000 mm, while FINE mode allows precise detection up to 2,000 mm. This dual-mode operation enables the sensor to handle both large-area monitoring and high-precision tasks, making it versatile for different production requirements.

The sensor is engineered to detect very small targets. In FINE mode, the smallest detectable object is 0.8 mm in diameter, while in TURBO mode, it can reliably detect objects as small as 1.2 mm. This high sensitivity is ideal for applications that require precise detection of thin, narrow, or intricate components.

Durability is a cornerstone of the PS-201C. Its Teflon®-sheathed construction and IP67-rated enclosure provide excellent protection against dust, water, and other contaminants, ensuring consistent performance even in harsh industrial conditions. The sensor operates effectively across a wide ambient temperature range of -10 to +60 °C and a relative humidity range of 35–85%, allowing reliable operation in environments with fluctuating temperatures or moderate humidity.

The use of an infrared LED light source ensures stable and reliable detection, even in the presence of bright ambient lighting. Infrared operation minimizes interference from external light sources, maintaining consistent performance on production lines with variable lighting conditions.

Compact yet robust, the PS-201C is ideal for industrial setups that demand long-distance sensing combined with precision and environmental resilience. Its versatility, high sensitivity, and durability make it an indispensable component for automated systems requiring reliable, high-speed detection over extended distances.
