E3G-R/MR
● Designing
Power Supply
A power supply with full-wave rectification can be connected to the
E3G-MR19(T).
● Wiring
The tensile strength of the cable during operation should not exceed
the values shown below.

*If the operating level is set to the stable operation range, the E3G will operate with the
highest reliability and without being influenced by temperature change, voltage fluctuation,
dust, or setting change. If the operating level cannot be set to the stable operation range,
pay close attention to environmental changes while operating the E3G.

● Mounting
Mounting
Mounting Directions
• Make sure that the sensing side of the
Sensor is parallel with the surface of
each sensing object. Do not incline the
Sensor towards the sensing object.
Sensing side
Surface of
sensing object
If the sensing object has a glossy
surface, incline the Sensor by 5° to 10°
as shown below, provided that the
Sensor is not influenced by any
background objects.
Glossy object
• If there is a mirror-like object below the Sensor, the Sensor may not
be in stable operation. Therefore, incline the Sensor or keep the
Sensor a distance away from the mirror-like object as shown below.
