What are the differences between E39-R1 General-purpose Reflectors and E39-R1K Reflectors with anti-fog coating?


E39-R1K Reflectors are the same as E39-RQ, except they have an anti-fog coating added to the reflective surface. The anti-fog effect of the coating is similar to that used by ski goggles.

The sensing distance with E39-R1K is the same as with E39-R1. For example, with E3Z-R Photoelectric Sensors with built-in amplifier, the sensing distance is 3 m whether E39-R1 or E39-R1K is used.
