PZ-G Series
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 |
25.4mm
M3
24.1mm
■ 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
Panel (5 mm or less) |
Panel cut size |
|
φ18.5 ± 0.2 mm |
Note |
|
• 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. |
|
|
|
Sensitivity Adjustment Method
Avoid using excess force when rotating the Caution sensitivity adjustment trimmer and
operation mode selector switch as it may cause damage.
■ 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.

Position target in place. Slowly rotate the sensitivity trimmer |
A |
|
|
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 |
MIN |
MAX |
|
Position "A". |
|
|
|
Remove the target. Adjust the sensitivity trimmer from MIN |
|
|
|
towards MAX until the (orange) output indicator turns on |
|
B |
|
(Position "B"). If the output indicator does not light up, the MAX |
|
|
|
position is considered Position "B". |
MIN |
MAX |
|
Adjust the sensitivity trimmer to the midpoint between "A" and |
A |
|
|
"B". Verify that the (green) stable operation light turns on with |
|
|
|
|
B |
|
|
and without a target in place. |

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