PRECAUTIONS FOR PROPER USE

Refer to 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.

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.

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.

• In case the

PM-24 series is used at an ambient

temperature of +50 °C +122 °F, or more, make sure to

mount it on a metal body.

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.

• 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.
