Keyence PZ-G102CN Photoelectric Sensor
The PZ-G102CN belongs to the Keyence PZ-G series of built-in amplifier photoelectric sensors. This model features a definite reflective sensing method within a durable rectangular housing. Engineers and technicians select this sensor for its precise detection capabilities over short distances. Its compact design allows integration into space-constrained machinery. The sensor provides a reliable solution for presence detection and positioning tasks in industrial automation.
Technical Specifications
The PZ-G102CN operates with a red LED light source. It achieves a detecting distance of 5 to 45 mm with a spot diameter of approximately 2 mm at a 40 mm distance. Users can adjust sensitivity via a single-turn trimmer with a 230-degree range. The response time is a quick 500 µs maximum, ensuring timely signal output for high-speed processes.
Furthermore, the sensor offers selectable LIGHT-ON and DARK-ON operation modes. The NPN open collector output handles a maximum of 30 V and 100 mA, with a residual voltage of 1 V or less. Additionally, the unit includes protection circuits against reversed polarity, overcurrent, and surge. Interference suppression supports up to two units through an automatic different frequency function.
Mechanical and Environmental Parameters
The PZ-G102CN features a glass-fiber reinforced PBT housing. Its lens cover uses acrylic (PMMA) material for optical clarity. The M8 connector ensures a secure and replaceable electrical connection. This sensor weighs approximately 10 g, making it lightweight and easy to mount.
Environmental resilience is a key strength of this model. It carries an IP67 rating and also meets NEMA 4A, 6, 12, and DIN IP69K standards. The operating temperature range spans from -20 to +55 °C. It resists vibration at 10 to 55 Hz and shock at 1,000 m/s². Moreover, the sensor tolerates ambient light up to 5,000 lux from incandescent lamps and 20,000 lux from sunlight.
Installation Guide
First, mount the PZ-G102CN using the provided mounting holes. Apply a maximum tightening torque of 0.5 N·m to avoid damaging the housing. Next, connect the M8 connector cable, which is sold separately. Ensure the supply voltage is within the 10 to 30 VDC range with ripple within 10%.
After wiring, power on the sensor and observe the green stable operation LED. Adjust the one-turn trimmer to set the desired sensitivity for the specific target and background. The orange output LED indicates detection status. Finally, select the appropriate LIGHT-ON or DARK-ON mode via the switch to match the control logic requirements.
