1. Durable and Long Life

The “hybrid structure” of the PR-M/F features an SUS316L stainless steel body that is also resin filled. The NEMA and IP rated enclosure means these units are highly resistant to oils, acids, and even alkaline detergents.


2. Stable Operation

The PR-M/F Series is designed with Background Suppression and Automatic Cross Talk Prevention to provide highly stable detection. External light or movement will not interfere with the sensor.

Stable Operation

3. Ease of Use

Installation is made simple because mounting requires only two M3 screws. Sensitivity adjustment is not needed, as the sensor's fixed range allows for immediate use.

Ease of Use
