Specifications
Ratings/Characteristics
Note:
1. Refers to the distance from the detecting surface to the passing position of the detectable object which permits positive detection
even when the sensing detecting surface is decreased due to temperature or voltage fluctuation.
2. The response frequencies for DC switching are average values measured on condition that the distance between each sensing
object is twice as large as the size of the standard object and the sensing distance set is half of the maximum sensing distance.
3. Refers to a change in detecting distance when the ambient operating temperature changes within Omron's specified range and
is expressed as the rate of variation (in percentage) with the detecting distance at the rated voltage taken as 100%.
4. Refers to a change in detecting distance when the supply voltage changes within a permissible range and is expressed as the
rate of variation (in percentage) with the detecting distance at the rated voltage taken as 100%.

Precautions
Effects of Surrounding Metal
If there is any metal near the sensor, the metal may effect the per-
formance of the E2R or the temperature of the metal may effect
the sensing distance of the E2R. Make sure that the clearances
given in the following illustrations are maintained for accurate
sensing operation.
Mutual Interference
When installing two or more E2R units face to face or side by
side, make sure that the minimum distances given in the following
illustration is maintained.
Handling and Connections
The E2R incorporates a connector. Do not solder connector pins
to lead wires. Use the E22-01 Connector or Molex connector
(housing 010308033 and terminal 008700057) or Japan Molex
connector (housing 5209-03 and terminal 5103).
Do not impose external force on the terminal as shown in the fol-
lowing illustration or else the terminal may be damaged.
Do not connect or disconnect the connector with the E2R turned
on as the E2R may be damaged.
Power Supply
When using a standard switching regulator with the E2R, ground
the frame ground (FG) and ground (G) terminals of the switching
regulator for stable operation.
