Keyence LR-ZB250C3P CMOS Laser Sensor PNP

Keyence LR-ZB250C3P CMOS Laser Sensor PNP

Product Introduction

The LR-ZB250C3P belongs to the Keyence LR-Z series. This self-contained CMOS laser photoelectric sensor uses distance and contrast detection. Furthermore, it delivers reliable performance across a 35 to 250 mm detecting range. The unit features a PNP open collector output and an M8 3-pin connector. Additionally, it supports IO-Link v1.1 for advanced communication. Its rectangular shape fits tight spaces on production lines. Meanwhile, the IP68 and IP69K ratings ensure protection against dust and high-pressure washdown. This makes the LR-ZB250C3P ideal for automotive, packaging, and food processing applications.

Technical Specifications

The LR-ZB250C3P provides a detecting distance of 35 to 250 mm. Standard detectable deviation is 9 mm for 35 to 180 mm and 25 mm for 180 to 250 mm. The display resolution ranges from 1 to 3 mm. Besides, the spot diameter is approximately 2.4 x 1.2 mm at 250 mm. The light source is a red laser with a 660 nm wavelength. It belongs to laser class 1 according to IEC60825-1 and FDA CDRH Part1040.10. Response time is selectable among 1.5 ms, 10 ms, and 50 ms. Moreover, a timer function supports OFF, ON-delay, OFF-delay, and one-shot modes.

Communication and Electrical Data

For communication, the LR-ZB250C3P offers IO-Link v1.1 and COM2 at 38.4 kbps on CB/C3P connector-type models. However, built-in ports are not available. The supply voltage ranges from 10 to 30 VDC with 10% ripple. Power consumption stays at 450 mW or less. Specifically, it draws 18 mA or less at 24 V and 34 mA or less at 12 V. The output type is PNP open collector with 30 VDC or less applied voltage. Control current is 100 mA or less, and residual voltage is 1.2 V or less at 10 mA or less. Output operation is selectable between Light-ON and Dark-ON.

Mechanical and Environmental Parameters

The operating temperature range is -10 to +50 °C without freezing. Storage temperature extends from -25 to +75 °C. Relative humidity stays between 35 and 85 % RH without condensation. The protection rating includes IP68, IP69K, and NEMA 4X / 6P / 13. These ratings confirm resistance to water, dust, and harsh cleaning agents. The sensor weighs approximately 0.055 kg. Dimensions are not available from the supplier. Therefore, please verify mounting space before installation.

Installation Guide

First, mount the LR-ZB250C3P using its rectangular body and standard brackets. Next, connect the M8 3-pin connector to the power and output lines. Then, set the supply voltage within 10 to 30 VDC. After that, select Light-ON or Dark-ON operation based on your logic. Furthermore, adjust the response time to 1.5 ms, 10 ms, or 50 ms for your application. Finally, configure the timer mode if delay or one-shot action is needed. For IO-Link use, connect the sensor to a compatible master. Besides, avoid direct sunlight and strong ambient light during setup. The IP68 and IP69K ratings allow washdown cleaning, but do not submerge the connector.
