Keyence LR-ZB250AP CMOS Laser Sensor PNP 2 m Cable

Keyence LR-ZB250AP CMOS Laser Sensor with PNP Output and 2 m Cable

Product Introduction

The LR-ZB250AP is a self-contained CMOS laser photoelectric sensor from the Keyence LR-Z series. This rectangular unit applies U.C.D. distance and contrast detection for reliable sensing. Moreover, it covers a detecting distance of 35 to 250 mm. The mid-range span suits presence checks, part positioning, and small-target verification.

A red laser with a 660 nm wavelength acts as the light source. Specifically, this model holds a Class 1 rating under IEC60825-1 and FDA CDRH Part1040.10. Therefore, it needs fewer safety controls than Class 2 devices. The spot diameter measures approximately 2.4 x 1.2 mm at 250 mm, which helps detect narrow edges.

The LR-ZB250AP delivers a PNP open collector output. Users may select Light-ON or Dark-ON operation to match controller logic. Meanwhile, the fixed 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 supported.

Technical Specifications

The detecting distance spans 35 to 250 mm for flexible mounting. Standard detectable deviation measures 9 mm from 35 to 180 mm. Furthermore, it reaches 25 mm from 180 to 250 mm. Display resolution ranges from 1 to 3, matching 1 to 3 mm settings.

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 works well with PLC input modules that expect a positive switching signal.

Mechanical and Environmental Parameters

The rectangular housing fits narrow installation spaces. The unit with its 2 m cable weighs approximately 110 g. Since 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-ZB250AP 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.
