Keyence PZ-G41CN Sensor | 1m Diffuse Reflective

PZ-G41CN Keyence Sensor | Long-Range Diffuse Reflective Detection

Product Introduction

The Keyence PZ-G41CN belongs to the PZ-G series of built-in amplifier photoelectric sensors. This rectangular diffuse reflective model uses a red LED light source. Specifically, it achieves a maximum detecting distance of 1 m (when detecting 30 × 30 cm white paper). Furthermore, the 500 µs response time supports high-speed production lines. The sensor uses NPN open collector output and operates on 10 to 30 VDC. Additionally, its IP67 and IP69K ratings ensure durability in harsh conditions.

Technical Specifications

The PZ-G41CN employs a red LED as its light source. Meanwhile, the 1-turn trimmer provides 230° sensitivity adjustment for precise calibration. Besides, users can select LIGHT-ON or DARK-ON operation via a switch. The control output handles 30 V maximum and 100 mA maximum with residual voltage of 1 V maximum. Moreover, built-in protection circuits guard against reversed polarity, overcurrent, and surges. For interference suppression, the sensor supports up to 2 units when polarization filters are attached.

Supply Voltage: 10 to 30 VDC (including ripple P-P 10%)
Current Consumption: 34 mA or less
Response Time: 500 µs maximum
Output Type: NPN open collector
Cable Connection: M8 connector

Mechanical and Environmental Parameters

The housing uses glass-fiber reinforced PBT for the main body. In addition, the lens cover features polyarylate (PAR) material. The operating temperature range spans -20 to +55 °C without freezing. Moreover, relative humidity tolerance reaches 35 to 85 % RH without condensation. For vibration resistance, the sensor endures 10 to 55 Hz at 1.5 mm double amplitude across X, Y, and Z directions. Finally, shock resistance reaches 1,000 m/s² for 6 times in each axis.

Protection Rating: IEC IP67 / NEMA 4A, 6, 12 / DIN IP69K
Ambient Light Resistance: Incandescent lamp 5,000 lux; Sunlight 20,000 lux
Mounting Torque: 0.5 N·m maximum (mounting hole part)

Installation Guide

First, verify the supply voltage stays within the 10 to 30 VDC range. Next, mount the sensor facing the target material across the detection zone. The PZ-G41CN uses an M8 connector for quick cable connection. Therefore, plan cable routing away from high-voltage lines to prevent interference. Then, adjust the 1-turn trimmer until the stable operation indicator (green LED) illuminates. Besides, the mounting hole part accepts up to 0.5 N·m torque. Finally, confirm the operating mode matches your application requirements.
