Product details

LR-ZB100N Keyence Self-contained CMOS Laser Sensor

The LR-ZB100N from Keyence is a distance based laser sensor. It uses a red laser and a CMOS element. This sensor is built for tough factory floors. It has a rectangular shape and a strong metal case. The LR-ZB100N gives stable detection from 35 to 100 mm. It is IP68 and IP69K rated. This means it survives high pressure washdown and dust. The sensor comes with a 2 m cable and NPN output. It is a Class 1 laser product, so it is safe for normal use.

Installation Guide

Mount the LR-ZB100N on a flat, stable surface.
Keep the spot size in mind. The beam is about 2 × 1 mm at 100 mm.
Use the 2 m cable to connect to a 10 to 30 VDC power supply.
Wire the NPN output to your PLC or control device.
Set the light ON or dark ON mode as needed.
For external input, use 35 ms or more ON for calibration.
To stop laser emission, apply 2 ms or more ON signal.
Do not block the lens. Keep the area free of strong light sources.

Setup and Maintenance

The 3 digit 7 segment display makes setup quick.
Use the DATUM indicator and spot indicator for easy alignment.
Timer modes include OFF delay, ON delay, and one shot.
Clean the lens cover with a soft cloth. Do not use harsh chemicals.
The SUS316L case resists corrosion and washdown.
Check the cable for damage. Replace if the jacket is cut.
No routine calibration is needed. The sensor is factory set.

Compatibility Notes

Works with most industrial PLCs using NPN input.
Compatible with 24 V and 12 V DC systems.
Can replace other 35 to 100 mm distance sensors.
Fits in tight spaces due to rectangular shape.
Suited for food and beverage lines because of ECOLAB and Diversey ratings.

Expert Review

The LR-ZB100N is a solid choice for factory automation. It blends a tough stainless steel body with a clear display. The 1.5 ms response time is fast for many sorting tasks. The IP69K rating means it handles high pressure cleaning. This sensor is not the cheapest, but it lasts. The laser class 1 makes it safe for operators. The spot size is small, so you can detect tiny parts. If you need a reliable distance sensor for food lines or machine tools, this model works well.

Manager’s Insight

We sell many laser sensors. The LR-ZB100N stands out for washdown areas. The SUS316L case resists acid and caustic cleaners. The NPN output fits most Asian and European PLCs. The 3 digit display cuts setup time. The timer functions reduce the need for external relays. For high mix production, the fast response helps. This is a workhorse sensor. It does not need much maintenance. For the price, you get Keyence quality and a long service life.

FAQ

Q: What is the difference between LR-ZB100N and other LR-ZB models?
A: The LR-ZB100N has a 35 to 100 mm range and NPN output. Other models may have different ranges or PNP output. Check the model code before you buy.

Q: Can this sensor work in direct sunlight?
A: Yes. It tolerates up to 8,000 lux of sunlight. But for best results, shield the sensor from strong direct light.

Q: How do I know if the sensor is aligned?
A: Use the green spot indicator. It shows when the beam hits the target. The orange DATUM indicator helps with calibration.

Q: What is the best response time setting?
A: Use 1.5 ms for fast moving parts. Use 10 ms or 50 ms for steady targets to reduce noise.

Q: Does the LR-ZB100N need a separate amplifier?
A: No. This is a self contained sensor. The amplifier is built into the housing.

Q: Can I use this sensor outdoors?
A: It is rated IP68 and IP69K. It handles rain and washdown. But avoid extreme temperatures outside the -10 to +50 °C range.

Q: What is the warranty period?
A: 12 months from the date of purchase. Contact sales@powergearx.com for claims.

Q: How fast do you ship?
A: We ship in 12 to 24 hours. We use FedEx, UPS, and DHL.

Q: Is the cable detachable?
A: No. The 2 m cable is fixed to the sensor body.

Q: What is the spot size at 50 mm?
A: The spot is smaller at 50 mm. It grows to about 2 × 1 mm at 100 mm.
