Keyence PZ-G102CB Photoelectric Sensor
The PZ-G102CB belongs to the Keyence PZ-G series of built-in amplifier photoelectric sensors. This model uses a definite reflective sensing method inside a threaded M18 nut-type housing. Maintenance teams favor this sensor for accurate detection over short distances. Its threaded barrel allows quick panel mounting and fine position adjustment. Therefore, the unit suits presence detection and positioning duties across modern automation lines.
Technical Specifications
The PZ-G102CB 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 chaotic (NPN + 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-G102CB uses a glass-fiber reinforced PBT housing. Its lens cover is acrylic (PMMA) for optical clarity. The M12 connector provides a secure electrical link, and the mating cable ships separately. Besides, the sensor weighs roughly 15 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-G102CB through its M18 threaded front or the side slotted hole. Apply a maximum torque of 1.0 N·m on the front thread and 0.5 N·m on the side hole. Next, attach the M12 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.
