Keyence PZ-G102CP Photoelectric Sensor
The PZ-G102CP is part of the Keyence PZ-G series of built-in amplifier photoelectric sensors. This model uses a definite reflective sensing method inside a sturdy rectangular housing. Engineers choose this sensor for accurate detection across short distances. Its small footprint fits easily into space-limited machines. Therefore, the unit serves presence detection and positioning duties in modern automation lines.
Technical Specifications
The PZ-G102CP works with a red LED light source. It reaches a detecting distance of 5 to 45 mm with a spot diameter near 2 mm at 40 mm. Sensitivity adjustment happens through a single-turn trimmer with a 230-degree range. Meanwhile, the response time stays at 500 µs maximum, which keeps signal output fast for high-speed processes.
Furthermore, users can select LIGHT-ON or DARK-ON operation modes. The PNP open collector output supports up to 30 V and 100 mA, with residual voltage at 1 V or less. In addition, built-in circuits guard against reversed polarity, overcurrent, and surge. Interference suppression allows up to two units through an automatic different frequency function.
Mechanical and Environmental Parameters
The PZ-G102CP uses a glass-fiber reinforced PBT housing. Its lens cover is acrylic (PMMA) for optical clarity. The M8 connector provides a secure, replaceable electrical link. Besides, the sensor weighs roughly 10 g, so mounting stays simple and light.
Environmental toughness stands out on this model. It holds an IP67 rating and meets NEMA 4A, 6, 12, and DIN IP69K standards. The operating temperature range runs from -20 to +55 °C. It also resists vibration at 10 to 55 Hz and shock at 1,000 m/s². Moreover, ambient light tolerance reaches 5,000 lux from incandescent lamps and 20,000 lux from sunlight.
Installation Guide
First, mount the PZ-G102CP through its mounting holes. Apply a maximum tightening torque of 0.5 N·m to protect the housing. Next, attach the M8 connector cable, which ships separately. Confirm the supply voltage stays within 10 to 30 VDC with ripple under 10%.
After wiring, power on the sensor and check the green stable operation LED. Then adjust the one-turn trimmer to set sensitivity for your target and background. The orange output LED shows detection status. Finally, pick LIGHT-ON or DARK-ON mode with the switch to match your control logic.

Frequently Asked Questions
Q1: What is the detecting distance of the PZ-G102CP?
A: The PZ-G102CP covers a detecting distance of 5 to 45 mm. The spot diameter measures about 2 mm at a 40 mm distance.
Q2: Does this sensor come with a cable?
A: No, the PZ-G102CP relies on an M8 connector. Buyers purchase the mating cable separately for flexible length and replacement options.
Q3: What output type does this model use?
A: This sensor provides a PNP open collector output. It handles a maximum load of 30 V and 100 mA.
Q4: Is the PZ-G102CP suitable for wet or washdown areas?
A: Yes. The PZ-G102CP carries IP67 and DIN IP69K ratings. It resists water and dust ingress well in tough environments.
Q5: How do I adjust detection sensitivity?
A: A 1-turn trimmer with a 230-degree range sits on the sensor body. Turn it to raise or lower sensitivity for your specific application.
