Keyence PZ-G102EN Photoelectric Sensor
The PZ-G102EN belongs to the Keyence PZ-G series of built-in amplifier photoelectric sensors. This model uses a definite reflective sensing method inside a rugged rectangular housing. Technicians select this sensor for accurate detection over short distances. Its small body fits easily into space-limited machinery. Therefore, the unit handles presence detection and positioning duties across modern automation lines.
Technical Specifications
The PZ-G102EN operates with a red LED light source. It achieves a detecting distance of 5 to 45 mm with a spot diameter near 2 mm at 40 mm. Sensitivity adjustment works 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 NPN 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-G102EN uses a glass-fiber reinforced PBT housing. Its lens cover is acrylic (PMMA) for optical clarity. The M12 pigtail connector provides a secure electrical link and simplifies cable routing. Besides, the sensor weighs roughly 30 g, so mounting stays simple and stable.
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-G102EN through its mounting holes. Apply a maximum tightening torque of 0.5 N·m to protect the housing. Next, connect the M12 pigtail leads to your control panel wiring. 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-G102EN?
A: The PZ-G102EN covers a detecting distance of 5 to 45 mm. The spot diameter measures about 2 mm at a 40 mm distance.
Q2: How does the M12 pigtail connector differ from an M8 model?
A: The PZ-G102EN ships with pre-wired M12 pigtail leads. This design removes the need for a separate mating cable and speeds up installation.
Q3: What output type does this model use?
A: This sensor provides an NPN open collector output. It handles a maximum load of 30 V and 100 mA.
Q4: Is the PZ-G102EN suitable for wet or washdown areas?
A: Yes. The PZ-G102EN 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.
