CAUTIONS



Since the sensor is intended for use inside machines, no special counter­measures have been taken against extraneous light. Please take care that
extraneous light is not directly incident on the beam receiving section.

When the connector CN-14 is inserted into the connector type PM-54(P), insert it
satraight till the hook of the connector is fitted to the hook of the sensor.
In order to pull the connector out, hold the connector body and then apply a force
to the extent that the hook of the connector comes off from the hook of the sensor.

 If soldering in done directly on the terminals of the connector type

PM-54(P) and the connector CN-14, solder them under the
following conditions: temperature 260C or less, time 3 sec. or less,
soldering position 1.5mm or more away from terminal base.



If the sensor is used in a place having excessive dust, periodically
clean the emitting and receiving sections with a dry, soft cloth.



Cable extension is possible up to an overall length of 100m with a 0.3mm

,
or more, cable. However, since 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.



I

f there is a large surge generating equipment, such as, motor, sole-

noid, electromagnetic valve, etc., in the vicinity of the micro-photo­sensor, use a surge absorber on that equipment.
Further, do not run the sensor cables along power lines and use a
capacitor between

V and 0V, if required. Use after confirming

that the surge has been eliminated.



In case the sensor is fixed with screws, strictly observe the following conditions.

 Do not use the sensor in the transient time duration of 50ms after

switching on the power supply.

 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 -10

.

Note:

If the ultra-small type PM-24(-R) is used at an ambient temperature of
50C or more, make sure to mount it on a metallic body.

WARNING



Never use this product as a sensing device for personnel
protection.



I

n case of using sensing devices for personnel protec­tion, use products which meet standards, such as
OSHA, ANSI or IEC etc., for personnels protection
applicable in each region or country.

WARNING



Take care not to apply any force to the terminal of the
connector type PM-54(P) and the connector CN-14.
Furthermore do not plug in/pull out the connector
more than 10 times, since it can cause contact-failure.



Since protection circuit against output short-circuit or
reverse polarity connection is not incorporated, make
sure to wire correctly. Also, ensure to insulate the
unused output wire.
Take care that wrong wiring will damage the sensor.
