What are the differences between E39-R1 Reflectors and E39-R1S Reflectors?


E39-R1S has better reflection efficiency and directionality than E39-R1, so more light returns to the receiver, which enables a longer sensing distance.

For reference, the sensing distance for E3Z-R Photoelectric Sensors are 3 m with the E39-R1 and 4 m with the E39-R1S.
