PRECAUTIONS FOR PROPER USE

Mounting
Note: In case the ultra-small type
When fixing the sensor with screws, use M3 screws
[M2 screws in case of PM- 24(-R)] and the tightening
torque should not exceed the values given below.
Further, use small, round type plain washers.

Since the sensor is intended for use
inside machines, no special counter-
measures have been taken against
extraneous light. Take care that extra-
neous light is not directly incident on
the beam receiving section.
Do not use during the initial transient time (50 ms) after the
power supply is switched on.
The cable of PM- 24-R is a flexible cable usable on a
moving base. When the sensor is mounted on a moving
base, fix the sensor cable joint so that stress is not applied
to it.
Take care that the flexibility of the PM- 24-R cable is lost
if the ambient temperature is near

This product is not a safety sensor. Its use is not
intended or designed to protect life and prevent body
injury or property damage from dangerous parts of
machinery. It is a normal object detection sensor.
Make sure to connect terminals correctly as the
sensor does not incorporate a reverse polarity
protection circuit.
Further, the output is not incorporated with a short-
circuit protection circuit. Do not connect it directly to
a power supply or a capacitive load. Faulty wiring
may result in damage.

a voltage drop shall occur due to the cable extension,
ensure that the power supply voltage at the end of the
cable attached to the sensor or at the sensor terminals is
within the rating.
But, when the overall cable length, including the cable
attached to the sensor, is as given below, there is no need
to confirm the voltage.
