MOUNTING
Placing of sensor heads
Make the sender and receiver face each other and align their sensing center line.
Keep a distance from any magnet or a device generating magnetic field. It may degrade the detectability.

To mount the sensor head with a nut, the thru-hole should be
(The mounting board must be 2.3mm, or less, thick.)
Distance from nearby metals
As metals near the sensor head may affect the sensing performance, pay attention to the following points.
Influence of nearby metal
The sensor head must be separated from nearby metal by a minimum distance as specified in the table below.

Embedding in metal
The sensing performance may be affected if the sensor is completely embedded in a metal. Keep a minimum clearance between the sensor
head and the metal as specified in the table below.

Interference prevention
When two or more sensor heads are mounted in parallel, keep a minimum separation distance as specified below to avoid interference.

Mounting of controller
On DIN rail
With the stopper pressed in the
direction of the arrow (it locks), fit
the front portion of the mounting
section of the amplifier on the
35mm width DIN rail.
Press and fit the rear portion of
the mounting section on the
35mm width DIN rail.
To remove, insert a flathead
screwdriver into the stopper and
pull out.
On board with screws
Use two M4 pan head screws
10mm, or more, long. The tight-
ening torque should be 1.2N m
or less.

or less. If your mounting panel is metallic, insert the attached insu-
lation plates at the terminals.
