The Keyence PX-H71TZ is a high-performance transmissive sensor head engineered for reliable detection in demanding industrial environments. Designed with a compact M8 hex-shaped housing and powered by a high-intensity LED light source, the PX-H71TZ provides exceptional long-distance sensing capabilities while maintaining accuracy for small object detection.

One of the standout features of the PX-H71TZ is its versatile detection range. Depending on the selected operating mode, the sensor can detect targets at distances of 4 m in TURBO mode, 6 m in SUPER mode, 12 m in ULTRA mode, and up to 20 m in MEGA mode. This flexibility allows users to adapt the sensor to a wide variety of applications, from close-proximity part verification to long-range detection across large conveyor or assembly systems.

The sensor incorporates a 4-element red LED light source (635 nm wavelength), designed to provide a concentrated, high-visibility beam. This ensures strong signal transmission, stable detection, and simplified alignment during installation. The enhanced optical output helps reduce the influence of dust, vibrations, or ambient light, ensuring accurate performance even in less-than-ideal environments.

Despite its long-range capabilities, the PX-H71TZ excels in precision. It is capable of detecting objects as small as ø4 mm opaque materials, making it suitable for applications where fine detection is essential—such as ensuring the presence of small components, counting items, or monitoring precision assembly processes. This ability to balance long-distance operation with small-object sensitivity highlights the advanced optical engineering of the PX series.

The M8 hex-shaped housing provides practical advantages during installation. Its compact form factor allows for easy integration into equipment layouts with limited space, while the hexagonal shape ensures secure mounting and reliable alignment. Weighing approximately 88 g including its cable, the unit offers a balance of sturdiness and ease of handling during setup.

Durability and reliability are inherent in the PX-H71TZ design. Built to Keyence’s rigorous standards, it withstands demanding industrial conditions and delivers consistent performance across a range of applications. Combined with its compatibility with PX-series amplifier units, users gain access to additional features such as interference prevention, mode selection, and signal optimization, ensuring a complete sensing solution tailored to production needs.

In summary, the Keyence PX-H71TZ transmissive sensor head offers a powerful combination of long-range capability, precision detection, and compact installation design. With its high-intensity LED source, multi-range operating modes, and ability to detect even small opaque objects, it is an excellent choice for engineers seeking reliable, versatile sensing in both short- and long-range applications. Whether used for high-speed production monitoring, assembly verification, or long-distance part detection, the PX-H71TZ delivers the performance and reliability expected from Keyence sensors.
