Keyence LR-ZB100CN CMOS Laser Sensor for High-Precision Short-Range Detection
Product Introduction
The LR-ZB100CN is a self-contained CMOS laser photoelectric sensor from the Keyence LR-Z series. This rectangular model uses U.C.D. distance and contrast detection for accurate sensing. Moreover, it covers a detecting distance of 35 to 100 mm. The short range and fine resolution suit precision positioning and small-part verification.
A red laser with a 660 nm wavelength acts as the light source. Specifically, this model carries a Class 1 rating under IEC60825-1 and FDA CDRH Part1040.10. Therefore, it requires fewer safety measures than Class 2 units. The spot diameter measures approximately 2 x 1 mm at 100 mm, which enables detection of tiny features.
The LR-ZB100CN provides an NPN open collector output. Users may choose Light-ON or Dark-ON operation to match controller logic. Meanwhile, the M8 4-pin connector simplifies wiring and fast replacement. 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 100 mm for close-range mounting. Standard detectable deviation measures 1.5 mm from 35 to 50 mm. Furthermore, it reaches 3 mm from 50 to 100 mm. Display resolution stays at 2, which equals 0.2 mm for fine adjustment.
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 an NPN 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 integrates easily with standard PLC input cards.
Mechanical and Environmental Parameters
The rectangular housing fits narrow installation spaces. Although exact dimensions are not available, the connector type weighs approximately 55 g. The M8 4-pin connection keeps cable routing tidy. 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 performs well in washdown and dusty settings.
Installation Guide
First, mount the LR-ZB100CN on a rigid bracket to avoid vibration errors. Next, align the laser spot with the target at the required distance. Then, connect the M8 4-pin cable between the sensor and the controller. 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.
