Frequently Asked Questions - NA1PK3PN PANASONIC
What is the sensing distance of the NA1PK3PN?
The NA1PK3PN has an adjustable sensing distance from 50 mm to 500 mm using the built-in sensitivity potentiometer. Set the distance according to your application.
How do I wire the NA1PK3PN?
The sensor has a 3-wire cable: brown (positive supply), blue (negative supply), and black (output). Connect the brown wire to 12–24 V DC, blue to 0 V, and black to the input of your controller. The output is PNP open collector.
What is the output type of the NA1PK3PN?
The output is a PNP open collector, which can sink current to ground when triggered. It is designed to interface with PLC inputs or other devices accepting a positive switching signal.
Can the NA1PK3PN be used outdoors?
With an IP67 enclosure rating, the sensor is protected against dust and temporary immersion in water, but it is not intended for outdoor use unless the cable entrance is properly sealed and the operating temperature is kept within -25°C to +55°C.
How do I clean and maintain the sensor?
Regularly wipe the lens with a soft, dry cloth to remove dust or dirt. Avoid using chemical solvents, as they may damage the polycarbonate lens. Inspect the cable and mounting screws periodically.
What happens if the sensor is connected with reverse polarity?
The NA1PK3PN includes a reverse polarity protection circuit, so incorrect wiring will not immediately damage the sensor. However, correct wiring should be restored to ensure reliable operation.
What is the response time of the sensor?
The typical response time is 1 ms or less, making it suitable for high-speed detection tasks such as counting or positioning.
Does the sensor have an indicator light?
Yes, the sensor has two LED indicators: a green power indicator confirming supply voltage is present, and an orange output indicator that lights when the output is active (object detected).
Can I adjust the sensing distance to avoid background interference?
Absolutely. Use the 25-turn potentiometer to fine-tune the detection range. Set the threshold so that only targets at the desired distance trigger the output, reducing false readings from background objects.
Where can I find spare parts or repair service for my sensor?
The sensor is not field-repairable. For spare parts like mounting brackets or connectors, contact an authorized Panasonic distributor. For repairs, return the unit to a Panasonic service center with proof of purchase.
