■Mutual interference

When installing a number of proximity
sensors of the same model either face-to­face or side-by-side, provide the minimum
distance given in the table between each
sensor.

1 PNP output types are different models from NPN output types and specified by letter P at the end of the model
numbers.(Ex : EM-030P)
2 Use a power range between 10.8 and 30V if ripple occurs.
3 The figures in ( ) are for PNP output type.

Influence of surrounding metallic
objects

● To flush mount the sensor that is
embedded in iron, provide enough
distance between the sensor and
surrounding iron as shown by the
following figure and table, because the
detecting distance is reduced by 10%.

cord with a conductor cross-sectional
area of 0.3mm2. Limit the length of the
extension to within 50m. Note that the
coaxial cord must not be extended or
cut.

● Ensure that the sensor cord is kept
away from power lines and high­tension lines; otherwise, noise may
cause the sensor to malfunction.
