Extremely small size enables space saving!!
Extremely small size and space saving
Equipped with two independent outputs
PM-24 series contributes to the miniaturization or space
saving of your equipment.
All models are equipped with two independent outputsLight-ON and Dark-ON.
Hence, one model suffices even if the output is to be
used differently, depending upon the location of use.
Also, since two independent outputs have been
provided, cumbersome handling of the output conversion
control input, or fear of logic inversion due to a cable
break, is eliminated. The sensor can be connected to the
existing wiring as it is.

PRECAUTIONS FOR PROPER USE
• Never use this product as a sensing device
for personnel protection.
• In case of using sensing devices for
personnel protection, use products which
meet laws and standards, such as OSHA,
ANSI or IEC etc., for personnel protection
applicable in each region or country.
Refer to p.1458~ for general precautions.
Cable extension
• Cable extension is possible up to an overall length of
100 m 328.084 ft with a 0.3 mm2, 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 is within the rating.
Total cable length 100 m 328.084 ft
Cable attached
to 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.
Mounting
• When fixing the sensor with screws, use M2 screws and
the tightening torque should be 0.15 N·m or less.
Further, use small, round type plain washers. (ø4.3 mm
ø0.169 in)
When using the optional mounting screw set MS-M2, a
spring washer is included.

mount it on a metal body.

Others
• Since the sensor is intended for
use inside machines, no special
countermeasures have been taken
against extraneous light. Take care
that extraneous 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. (Models other than the PM-□24-R cannot be
used on a moving base.)
• Take care that the flexibility of the PM-□24-R cable is lost
if the ambient temperature is –10 °C +14 °F or less.
