Effects of Surrounding Metal
Provide a minimum distance as shown in the table below be-
tween the Sensor and the surrounding metal.
Effects of Surrounding Metal (Unit: mm)
Mutual Interference
When installing two or more E2EZ face to face or side by side,
ensure that the minimum distances given in the following table
maintained.
Aluminum and Cast Iron Cut Chips
A detection signal will not be output if aluminum or cast iron
cut chips are stuck to the sensing face. Under the following
conditions, however, the proximity sensor may output detec-
tion signals, in which case remove the cut chips from the
sensing face.
Mounting
Do not tighten the nut with excessive force. A washer must be
used with the nut.
Note: 1 . The table below shows the tightening torques for part A and part B
nuts. In the previous examples, the nut is on the sensor head side
(part B) and hence the tightening torque for part B applies. If this nut
is in part A, the tightening torque for part A applies instead.
2 . The table below shows the value of tightening torques when using
toothed washers.
