Keyence LR-ZH500P CMOS Laser Sensor PNP 2 m Cable

Keyence LR-ZH500P CMOS Laser Sensor with PNP Output and 2 m Cable

Product Introduction

The LR-ZH500P is a self-contained CMOS laser photoelectric sensor from the Keyence LR-Z series. This rectangular unit relies on U.C.D. distance and contrast detection for stable sensing. Moreover, it covers a detecting distance of 35 to 500 mm. The wide range suits presence checks, positioning, and height verification on production lines.

A red laser with a 660 nm wavelength serves as the light source. Specifically, this model carries a Class 2 rating under IEC60825-1 and FDA CDRH Part1040.10. Therefore, installers should follow standard laser safety practices. The spot diameter measures approximately ø3 mm, which supports precise targeting at longer distances.

The LR-ZH500P provides a PNP open collector output. Users may choose Light-ON or Dark-ON operation to match controller logic. Meanwhile, the 2 m cable removes the need for a separate connector cord. On CB/C3P connector-type models, IO-Link v1.1 and COM2 at 38.4 kbps are also available.

Technical Specifications

The detecting distance spans 35 to 500 mm for flexible mounting. Standard detectable deviation varies across the range. For instance, it measures 9 mm from 35 to 180 mm. Furthermore, it reaches 25 mm from 180 to 300 mm, 40 mm from 300 to 400 mm, and 50 mm from 400 to 500 mm. Display resolution ranges from 1 to 5, matching 1 to 5 mm.

Response time offers three selectable values: 1.5 ms, 10 ms, and 50 ms. Besides, a built-in timer provides OFF, ON-delay, OFF-delay, and one-shot modes. The supply voltage accepts 10 to 30 VDC with 10% ripple (P-P), using Class 2 or LPS sources. Power consumption stays at 450 mW or less, drawing 18 mA or less at 24 V and 34 mA or less at 12 V.

The output uses a PNP open collector design. Its applied voltage reaches 30 VDC or less, with control current at 100 mA or less. Residual voltage remains 1.2 V or less at 10 mA or less. Therefore, the sensor pairs well with PLC input modules that expect a positive switching signal.

Mechanical and Environmental Parameters

The rectangular housing fits narrow installation areas. The unit with its 2 m cable weighs approximately 110 g. Because the cable is fixed, users avoid extra connector purchases. Additionally, the protection rating includes IP68 (IEC60529), IP69K (DIN40050-9), and NEMA 4X / 6P / 13.

Operating temperature ranges from -10 to +50 °C without freezing. Storage temperature spans -25 to +75 °C, also without freezing. Relative humidity stays between 35 and 85 % RH with no condensation. Consequently, the sensor tolerates washdown, dust, and outdoor enclosure conditions.

Installation Guide

First, mount the LR-ZH500P on a rigid bracket to prevent vibration errors. Next, align the laser spot with the target at the required distance. Then, route the 2 m cable to the controller and secure it with clamps. After that, set the response time and timer mode through the display.

Operators should confirm the Light-ON or Dark-ON setting before startup. Also, clean the lens regularly to preserve detection accuracy. For IO-Link models, configure COM2 parameters through the master device. Finally, verify the output signal with a multimeter or PLC monitor.
