DATE:
E3T-SR3 Photoelectric Sensors Discontinued March 2010;
Use E3T-SR4 Sensor and E39-R37-CA Reflector Instead
Omron completed its discontinuation of E3T-SR3 series Retroreflective sensor March 2010. For
most applications the E3T-SR4 series can be a direct replacement. However, the optics changed
from separate lenses for emitter and receiver in E3T-SR3 to a coaxial lens arrangement in E3T-SR4.
The change in optics also affects the choice of reflectors: Only models that end in “-CA” can be used
with E3T-SR4. When changing E3T-SR3 sensors, the E39-R37 reflector also must be changed.
* These reflectors are not discontinued, but they are not compatible with E3T-SR4 sensors.
