Keyence PZ-G41CB Diffuse Reflective Sensor

Keyence PZ-G41CB Diffuse Reflective Sensor

Product Introduction

The Keyence PZ-G41CB belongs to the PZ-G series of built-in amplifier photoelectric sensors. Specifically, this model uses a diffuse reflective sensing method with a long-range capability. It detects targets up to 1 meter away when using a 30 × 30 cm white paper standard. Furthermore, the threaded M18 nut shape allows simple mounting in tight spaces. The sensor includes a red LED light source and a 1-turn trimmer for sensitivity adjustment. Additionally, its dual NPN plus PNP open collector output supports diverse control systems. Therefore, this device fits many factory automation tasks.

Technical Specifications

First, the PZ-G41CB provides a maximum response time of 500 µs. This fast reaction suits high-speed detection lines. The operation mode switches between LIGHT-ON and DARK-ON. Meanwhile, an orange LED shows output status, and a green LED indicates stable operation. The sensitivity trimmer rotates 230 degrees for fine tuning.

Electrical Characteristics

Next, the supply voltage ranges from 10 to 30 VDC nominal. Ripple tolerance reaches 10% peak-to-peak. Current consumption stays at 34 mA or less. The control output handles 30 V and 100 mA maximum with residual voltage below 1 V. Besides, protection circuits include reversed polarity, overcurrent, and surge absorption. The M12 connector requires a separate cable. For interference suppression, the sensor supports up to two units via polarization filters or automatic frequency switching.

Mechanical and Environmental Parameters

Moreover, the housing uses glass-fiber reinforced PBT. The lens cover is polyarylate (PAR). The PZ-G41CB weighs approximately 15 g. Operating temperature spans -20 to +55 °C without freezing. Relative humidity stays between 35 and 85 % RH without condensation. The protection rating meets IEC IP67, NEMA 4A, 6, 12, and DIN IP69K. Ambient light resistance reaches 5,000 lux for incandescent lamps and 20,000 lux for sunlight. Vibration resistance covers 10 to 55 Hz with 1.5 mm double amplitude for 2 hours per axis. Shock resistance reaches 1,000 m/s² six times per axis.

Installation Guide

Proper mounting ensures reliable performance. First, use the front M18 part with a maximum torque of 1.0 N·m. The side slotted hole part accepts 0.5 N·m maximum. Next, connect the M12 connector cable carefully. Then, adjust the 1-turn trimmer to set sensitivity for your target. Meanwhile, avoid strong ambient light exceeding the rated lux values. Furthermore, keep the lens cover clean for accurate detection. Finally, verify the green stable operation LED before full operation.
