Keyence PZ-G52N Photoelectric Sensor | 40m Thrubeam

PZ-G52N Keyence Sensor | High-Power Thrubeam Detection Solution

Product Introduction

The Keyence PZ-G52N belongs to the PZ-G series of built-in amplifier photoelectric sensors. This rectangular thrubeam model delivers high-power infrared light for reliable long-distance detection. Specifically, it achieves a maximum detecting distance of 40 m (131.2 ft). 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-G52N employs two infrared LEDs 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: Transmitter: 25 mA or less; Receiver: 28 mA or less
Response Time: 500 µs maximum
Output Type: NPN open collector
Cable Connection: Cable (2 m)

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 transmitter and receiver units facing each other across the detection zone. The PZ-G52N uses a 2 m cable for 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.
