Instruction Manual

Read this manual thoroughly before using the product.
Keep this manual readily available for future reference.

Safety precautions

Avoid running the PZ-G cable along with power and high voltage lines, as this may cause
interference and/or permanent damage.

When using a commercially available switching regulator, ground its chassis grounding and
earth grounding terminals.

Do not use in locations where direct ambient light or external light directly shines on the light
receiving surface.

With retro-reflective type sensors, when detecting highly reflective materials (such as mirrored
surfaces), stabilization may be difficult. To correct this, change the angle of the sensor head, or
adjust the sensitivity.

Avoid using power which exceeds the specifications for ripple (10% max)

Avoid using excess force when rotating the operation mode selector switch (Light-on, Dark-on)
and the sensitivity adjustment trimmer.

This product is just intended to detect the object(s). Do not use this product for the purpose to
protect a human body or a part of human body.

This product is not intended for use as explosion-proof product. Do not use this product in a
hazardous location and/or potentially explosive atmosphere.

Side Mounting

(Prepare M3 screws)

Tightening torque: 0.5 N·m or less

Tightening torque: 0.5 N·m or less

Mounting with the M18 nut (includes nut type)

The M18 nut is also available separately as OP-84225 (2 pcs. supplied).
Tightening torque:1.0 N·m or less

Mount the M18 nut (supplied) straight in. If mounted at an angle it cannot be
tightened properly.

When tightening the M18 nut (supplied), firmly hold the main body down. The
case of the main body may be damaged if held in place with a tool such as pliers.

When tightening the M18 nut (supplied), if excess force is applied to the nut with a
tool such as pliers, it may bend it out of shape. Therefore, do not apply excess force.

Operation mode selector switch

With the operation mode selector switch, you can select either the LIGHT-ON mode (L) or the
DARK-ON (D) mode.

Reflective type (PZ-G41/G42/G101/G102/G10R/G10G/G10B
Series)

The following assumes LIGHT-ON (L) is set.

To use the sensor in DARK-ON mode, adjust the mode selector switch to "D".

Thrubeam type (PZ-G51/G52 Series) / Retro-reflective type (PZ-G61/G62
Series)

The following assumes DARK-ON (D) is set.

To use the sensor in LIGHT-ON mode, adjust the mode selector switch to "L".

* The pin numbers represent those of the connector type / pigtail quick disconnect type.

The model name with "C" (PZ-GxxCx) is the connector type, and the model name with "E"
(PZ-GxxEx) is the pigtail quick disconnect type.

Sensitivity Adjustment Method

Caution

Avoid using excess force when rotating the
sensitivity adjustment trimmer and
operation mode selector switch as it may
cause damage.

Sequence

Adjustment method

Sensitivity adjustment

trimmer

Position target in place. Slowly rotate the sensitivity trimmer
from the MIN position towards the MAX position until the
(orange) output indicator turns on (Position "A"). If the output
indicator does not turn off, even at MIN, then MIN is considered
Position "A".

Remove the target. Adjust the sensitivity trimmer from MIN
towards MAX until the (orange) output indicator turns on
(Position "B"). If the output indicator does not light up, the MAX
position is considered Position "B".

Adjust the sensitivity trimmer to the midpoint between "A" and
"B". Verify that the (green) stable operation light turns on with
and without a target in place.

Sequence

Adjustment method

Sensitivity adjustment

trimmer

Remove the target. Adjust the sensitivity trimmer to MAX. Mount
the sensor heads in place so the (orange) output indicator turns
off (on thrubeam models, the red light on the receiver face will
turn on)

Position target in place. Verify that the orange output indicator
turns on (on thrubeam models, the red light on the receiver face
will turn off). Adjust sensitivity lower if the output indicator does
not turn on (or if the red light on the receiver face does not turn
off on thrubeam models)
