Frequently Asked Questions - CX412PZ PANASONIC

How to wire the CX412PZ sensor?

Wiring must be carried out with power off. Connect the brown wire to +V (12-24 V DC), the blue wire to 0 V, and the black wire to the output (load). Observe polarity and do not exceed 100 mA.

How to adjust the sensor sensitivity?

Turn the sensitivity adjustment potentiometer. In Light-ON mode, start fully counterclockwise (MIN), then slowly turn clockwise until the output activates under 'light received' condition. Then, under 'dark' condition, turn until deactivation to find the optimal zone.

What is the difference between Light-ON and Dark-ON?

In Light-ON mode, the output is active when the sensor receives light. In Dark-ON mode, the output is active in absence of light. The switch on the sensor allows choosing the mode.

Can I use the CX412PZ for personnel protection?

No, this sensor is not designed for personnel protection. Use devices compliant with OSHA, ANSI, or IEC standards.

How to install the sensor in through-beam version?

Place the emitter and receiver facing each other in a straight line. Turn on the sensor in Light-ON mode, then adjust the alignment by moving the emitter and receiver until the operation indicator lights up. Then lock the angle.

What to do if the sensor does not detect correctly?

Check the alignment, cleanliness of lenses, power supply voltage, and sensitivity adjustment. Ensure the object is within range and the operation mode is suitable.

Can multiple sensors be installed side by side?

Yes, thanks to the automatic interference suppression function (except through-beam version). For through-beam version, use interference suppression filters (PF-CX4-H or PF-CX4-V).

How to clean the sensor?

Use a soft dry cloth to clean the housing and lens. Never use organic solvents, oil, or grease.

What accessories are available for the CX412PZ?

Accessories include connector cables (M8 or M12), apertures for small objects (OS-CX-...), interference suppression filters (PF-CX4), and an RF-230 reflector.

What is the maximum extension cable length?

The cable can be extended up to 100 m maximum with a cable of minimum cross-section 0.3 mm². Ensure noise reduction by using as short wiring as possible.

USER MANUAL CX412PZ PANASONIC

Thank you very much for using SUNX products. Please read this Instruction Manual carefully and thoroughly for the correct and optimum use of this product. Kindly keep this manual in a convenient place for quick reference.

WARNING

• 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.

1 CAUTIONS

● Make sure to carry out wiring with the power OFF.
- Incorrect wiring will damage the sensor.
- Verify that the supply voltage including the ripple is within the rating.
- If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
- In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
- Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
- Do not use during the initial transient time (50ms) after the power supply is switched on.
● ● This sensor is suitable for indoor use only.
- ● You can extend the cable up to 100m max. with 0.3mm or more cable. However, in order to reduce noise, make the wiring as short as possible.
- Do not apply stress directly to the sensor cable joint by forcibly bending or pulling.
- Do not use this sensor in places having excessive vapor, dust, etc., or where it may come in direct contact with water or corrosive gas.
● Take care that the sensor does not come in direct contact with water, oil grease, or organic solvents such as thinners, etc.

Thru-beam type sensor

①Set the operation mode switch to the Light-ON mode position (L side).
②Placing the emitter and the receiver face to face along a straight line. Move the emitter up, down, left and right to determine where light is received with the help of the receiver's operation indicator (orange). Set the emitter in the middle of this area.
③Adjust the angle of the emitter by twisting it up, down, left and right.
④In a similar manner, adjust the angle of the receiver.
⑤Check that the stability indicator (green) lights up.
⑥ Choose the desired operation mode, Light-ON or Dark-ON, with the operation mode switch.

6 SENSITIVITY ADJUSTMENT

To understand sensitivity adjustment, you must first understand the difference between the "light received" and the "dark" condition.

Do not confuse the "light received" and "dark" condition with the operation modes "Light-ON" and "Dark-ON"!

Thru-beamRetroref	Light received condition Dark condition
		Object to be sensed	ReceiverB
	Sensor Reflector	Sensor Object to be sensed	Reflector [2014]

Relationship between output and indicators

Stability indicator	Operation indicator	Output	Sensing condition	Output	Operation indicator	Stability indicator
		ON	Stable light	OFF
			Unstable light
		OFF	Unstable dark	ON
			Stable dark

⊙= lit, ●= unlit

Use a standard screwdriver and turn the adjuster slowly. Using excessive force will damage the adjuster.

This procedure assumes that "Light-ON" is set for the operation mode.

If "Dark-ON" is the operation mode, the output will behave the other way around!

Step	Sensitivity adjuster	Description
1Turnitter	the sensitivity adjuster fully counter-clockwise to the minimum sensitivity position, MIN.
2In the "light received" condition, turn the sensitivity adjuster slowly clockwise to find point A where the sensor output turns ON.*1
3In the position, turn the sensitivity adjuster clockwise until the sensor output turns ON.*1
4The position exactly between points A and B is the optimum sensing position.

^*1 Remember, this only applies if the operation mode is Light-ON.

7 AUTOMATIC INTERFERENCE PREVENTION FUNCTION

This function is not available for the thru-beam type sensor. See "INTERFERENCE PREVENTION FILTERS" on page 4.

The automatic interference prevention function allows you to mount up to two sets of sensors next to each other.

RETROREFLECTIVE TYPE SENSOR WITH POLARIZING FILTERS

As light is polarized by a transparent film or membrane, CX-491 may not detect an object covered or wrapped by transparent film. Such objects include, for example:

● Can wrapped by clear film
● ● Aluminum sheet covered by plastic film
● Gold or silver (glossy) labels or wrapping paper

In such cases, take the following steps.

①Tilt the sensor with respect to the object to be sensed.
②Reduce the sensitivity.
③ Increase the distance between the sensor and the object to be sensed.

SLIT MASKS

The slit mask is only available for the thru-beam type sensor.

Optional slit masks help the sensor detect small objects. However, the sensing range is reduced.

Type Model no.	Slit size
Round slit mask	OS-CX-05 = 0.5mm
	OS-CX-1 = 1mm
	OS-CX-2 = 2mm
Rectangular slit mask	OS-CX-05 x 6 0.5 × 6mm
	OS-CX-1 x 6 1 × 6mm
	OS-CX-2 x 6 2 × 6mm

Slit mask ① ② ③

How to mount

①Insert the hook (1) into the bottom groove (2).
② Press the slit mask until it snaps into the grooves (3) on the top of the main unit.

How to remove

①Insert a screw driver into the tab (4).
②Lift and remove carefully.

NTERFERENCE PREVENTION FILTERS

Interference prevention filters are only available for the thru-beam type sensor.

By mounting interference prevention filters, two sets of thru-beam type sensors can be mounted close together. However, the sensing range is reduced.

The filters can be mounted using the same method as for slit masks. For details, see page 4, section 9, SLIT MASKS.

For interference prevention to work, the following conditions must be met.

● The two sets of sensors must be fitted with different types of interference prevention filters.
● Filters must be mounted on emitters and receivers.

PF-CX4-H PF-CX4-V

Model no.	Direction of thru-beam axis	Color of the bracket
PF-CX4-H Horizontal	Light brown
PF-CX4-V	Vertical	Silver

The model no. is not shown on the interference prevention filters. Take care when mounting them on the sensors.
