Keyence PZ-G52CB Thrubeam Photoelectric Sensor

Keyence PZ-G52CB High-Power Thrubeam Sensor

Product Introduction

The PZ-G52CB belongs to the Keyence PZ-G series. This built-in amplifier photoelectric sensor uses a thrubeam design. Specifically, it delivers high-power performance for long-distance detection. The PZ-G52CB reaches a maximum detecting distance of 40 m. Therefore, it suits demanding industrial automation tasks.

This sensor features two infrared LEDs as its light source. Additionally, a 1-turn trimmer provides sensitivity adjustment across 230 degrees. The response time is 500 µs maximum. Meanwhile, the operation mode supports LIGHT-ON and DARK-ON selection. Users can switch modes easily via a selector. The PZ-G52CB also includes multiple LED indicators. For instance, the power indicator (T) is orange. The output indicator (R) is orange as well. Furthermore, a green LED shows stable operation. A red LED indicates light reception.

Technical Specifications

The supply voltage ranges from 10 to 30 VDC nominal. Ripple (P-P) is 10% maximum. Current consumption stays low. Specifically, the transmitter draws 25 mA or less. The receiver draws 28 mA or less. The output type uses two selectable output channels. This means it provides both NPN and PNP outputs. The control output handles 30 V maximum and 100 mA maximum. Residual voltage is 1 V maximum. Besides, protection circuits include reversed polarity, overcurrent protection, and a surge absorber.

Interference suppression supports up to 2 units. This works through polarization filters or an automatic different frequency function. The cable connection uses an M12 connector. However, the cable is sold separately. The PZ-G52CB does not include built-in communication ports. It also lacks protocols or communication expansion. Therefore, it operates as a standalone sensing device.

Mechanical and Environmental Parameters

The sensor comes in a threaded M18 nut type shape. Its housing uses glass-fiber reinforced PBT. The lens cover material is polyarylate (PAR). The weight is approximately 15 g. Dimensions (H×W×D) are not available. Mounting torque is 1.0 N·m maximum for the front M18 part. For the side slotted hole part, torque is 0.5 N·m maximum.

Environmental tolerance is strong. The operating temperature ranges from -20 to +55 °C. No freezing is allowed. Relative humidity stays between 35 and 85 % RH. No condensation is permitted. The protection rating meets IEC IP67, NEMA 4A, 6, 12, and DIN IP69K. Ambient light resistance handles incandescent lamp at 5,000 lux maximum. Sunlight resistance reaches 20,000 lux maximum. Vibration resistance covers 10 to 55 Hz. Double amplitude is 1.5 mm for 2 hours in each X, Y, Z direction. Shock resistance is 1,000 m/s². This applies 6 times in each X, Y, Z direction.

Installation Guide

First, verify the supply voltage matches 10 to 30 VDC. Next, mount the sensor using the M18 threaded body. Apply the correct torque. Specifically, use 1.0 N·m maximum on the front M18 part. For the side slotted hole, use 0.5 N·m maximum. Then, connect the M12 connector cable. Remember that the cable is sold separately. After that, adjust sensitivity with the 1-turn trimmer. The trimmer rotates 230 degrees. Meanwhile, select LIGHT-ON or DARK-ON mode as needed. Finally, confirm the LED indicators for stable operation.
