Keyence PZ-G42CB Photoelectric Sensor
The PZ-G42CB belongs to the Keyence PZ-G series of built-in amplifier photoelectric sensors. This diffuse reflective short-range model fits M18 threaded mounting holes. Engineers commonly specify it for presence detection, part counting, and position sensing on production lines.
Technical Specifications
Light source: Red LED
Detecting distance: 300 mm maximum (10 × 10 cm white paper)
Sensitivity adjustment: 1-turn trimmer (230°)
Response time: 500 µs maximum
Operation mode: LIGHT-ON/DARK-ON (switch-selectable)
Control output: 30 V maximum, 100 mA maximum, residual voltage 1 V maximum
Supply voltage: 10 to 30 VDC nominal, ripple (P-P) 10%
Current consumption: 34 mA or less
Cable connection: M12 connector (cable sold separately)
Indicators: Output orange LED, stable operation green LED
Protection circuits include reversed polarity, overcurrent protection, and a surge absorber. Interference suppression handles up to 2 units through polarization filters or the automatic different frequency function. Furthermore, the built-in ports and protocols are none, so the sensor works as a standalone device without communication expansion.
Mechanical and Environmental Parameters
The housing uses glass-fiber reinforced PBT for durability. The lens cover is polyarylate (PAR). Besides, the sensor weighs approximately 15 g and fits M18 nut-type mounting.
Housing material: Glass-fiber reinforced PBT
Lens cover material: Polyarylate (PAR)
Weight: Approx. 15 g
Mounting torque: 1.0 N·m maximum (front M18 part), 0.5 N·m maximum (side slotted hole part)
Operating temperature ranges from -20 to +55 °C with no freezing. Relative humidity stays at 35 to 85 % RH without condensation. The protection rating covers IEC IP67, NEMA 4A, 6, 12, and DIN IP69K. Ambient light resistance reaches 5,000 lux for incandescent lamps and 20,000 lux for sunlight.
Vibration resistance handles 10 to 55 Hz with 1.5 mm double amplitude for 2 hours in each X, Y, Z direction. Shock resistance reaches 1,000 m/s², 6 times in each X, Y, Z direction. Therefore, the PZ-G42CB performs reliably in vibrating machinery and outdoor installations.

FAQ
Q1: What is the maximum detection distance of the PZ-G42CB?
A: The sensor detects 10 × 10 cm white paper at up to 300 mm. Detection range varies with target size, color, and surface finish.
Q2: Does the PZ-G42CB support both NPN and PNP outputs?
A: Yes. It provides a chaotic NPN + PNP open collector output rated at 30 V and 100 mA maximum. This design suits mixed PLC environments without extra wiring.
Q3: What connector does this sensor use?
A: The PZ-G42CB uses an M12 connector, and the cable is sold separately. Confirm the pinout before ordering your cable.
Q4: Can the PZ-G42CB handle washdown environments?
A: Yes. It carries IEC IP67, NEMA 4A/6/12, and DIN IP69K ratings. The glass-fiber reinforced PBT housing resists water and dust ingress.
Q5: How do I adjust sensitivity on the PZ-G42CB?
A: Turn the 1-turn trimmer with 230° travel to set sensitivity. Watch the green stable operation LED and orange output LED during adjustment.
