Question

How do I interpret the catalog values for mutual interference with Proximity Sensors?

Answer

Refer to the following figures.

Mutual Interference

Use Sensors with the values in the following table or higher when they are mounted facing each other or in parallel.

ModelItemM8M12M18M30
DC 2-Wire Models
E2E-X[]D[]

AC/DC 2-Wire Models
E2E-X[]T1
ShieldedA2030 (20)50 (30)100 (50)
B1520 (12)35 (18)70 (35)
UnshieldedA80120 (60)200 (100)300 (100)
B60100 (50)110 (60)200 (100)

Note:Values in parentheses apply to Sensors operating at different frequencies.

The values listed above are given in the precautions section of the catalog. Dimensions A and B are specified by the way in which the Proximity Sensors are arranged. If a gap cannot be provided between the Proximity Sensors, they can be used close together up to the catalog values in parentheses by using a standard model in combination with a model that has a different frequency.

Note:Two of the Sensors with a different frequency cannot be used near each other. Leave a gap of at least the value not in parentheses.
