Sensitivity Adjustment
■ PZ-V (Digital type)
● Detect a moving target (Fully-automatic calibration)
Operation
● To detect a stationary target (Two-point calibration)
Operation
● To obtain maximum sensitivity (Maximum sensitivity setting)
Operation
Note:If the green LED turns off or " - - - " flashes after the calibration, the sensitivity has no
allowance. In such a case, adjust the sensor head position, and calibrate again.
● Fine sensitivity adjustment
• When the or button is pressed and released, the numerical value flashes (approx. 2
seconds). This is the preset value. If the or button is pressed again while the preset
value flashes, the preset value can be increased or decreased.
• When the or button is held down for 3 seconds or more, the preset value increases/
decreases continuously.

■ Distance display
• The greater the distance between the target and the sensor head, the larger the displayed value
becomes.
• If the target or background is out of the detectable range, is displayed.
Note 1: The distance value indicates a reference value only. It is not an absolute distance.
Note 2: If the target approaches the sensor head closer than the specified range, the
displayed value may increase.
■ PZ-M (Trimmer type)
• DARK-ON mode (When LIGHT-ON mode is selected, refer to the

WARNING
•
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.
• To extend the cable length, use a cable with at least a 0.3 mm2 nominal cross-section
area. Limit the length of cable extension to no more than 100 m.
• If the amplifier cable is placed together with power lines or high voltage lines in the same
conduit, a detection error may occur due to noise interference, or the sensor may be
damaged. Isolate the amplifier cable from these lines.
• When using a commercially available switching regulator, ground the frame ground
terminal and ground terminal.
• Do not use the PZ-V/PZ-M series outdoors or in a place where extraneous light can
enter the light-receiving surface directly.
• When the multi-reflective type is used for the detection of a target with high reflectivity
(e.g. mirror-surfaced object), proper detection or distance adjustment may be disabled.
In such a case, tilt the sensor head at some angle.
• During maximum sensitivity setting, the detecting distance may vary due to a difference
in characteristics of each unit.
• Be sure to check that the wiring is properly established. Improper wiring may cause a
decrease in sensitivity or overheating and sensor damage. (See “I/O Circuit”.)
• To mount the sensor, use an M3 screw (coarse thread). Limit the tightening torque to
0.6 N•m or less.
• To mount PZ-M71/V71, use an M4 screw (coarse thread). Limit the tightening torque to
0.7 N•m or less.
• To attach the R-5 reflector, use an M3 screw (coarse thread). Limit the tightening torque
to 0.3 N•m or less.
• The displayed value may vary depending on the surrounding environment, such as
temperature change or dust.
• Use a stable power supply. The sensor cannot operate properly if the power supply is
unstable at power-on or if the ripple exceeds the specified range.
Mutual Interference
• The alternate-frequency type allows mutual interference suppression up to two sensors.
• The alternate-frequency type is not available for the thrubeam type.
• To suppress the mutual interference with the thrubeam type or with three or more
sensors, contact KEYENCE.
Sensor Head Orientation
To detect a moving target, consider orientation of the sensor head according
to the direction of the movement.
