Keyence PZ-G101CN Narrow View Sensor

Keyence PZ-G101CN Photoelectric Sensor

The PZ-G101CN belongs to the Keyence PZ-G series of built-in amplifier photoelectric sensors. This narrow view reflective model uses a rectangular housing that mounts easily on brackets and machine frames. Engineers commonly specify it for detecting small parts, edge positioning, and mark sensing where a tight spot is essential.

Its narrow view optics produce an approximate 5 mm spot diameter at a 100 mm distance. Meanwhile, the M8 connector allows quick cable replacement without rewiring. The PZ-G101CN also provides a switch-selectable LIGHT-ON or DARK-ON operation mode for flexible logic setup.

Technical Specifications

The PZ-G101CN detects targets at a maximum distance of 200 mm (7.87 in). A red LED serves as the light source. Sensitivity adjustment uses a 1-turn trimmer with 230° travel. Response time stays at 500 µs or less, which suits most high-speed conveyor applications.

Spot diameter: Approx. 5 mm dia. at 100 mm (detecting distance)
Sensitivity adjustment: 1-turn trimmer (230°)
Response time: 500 µs maximum
Operation mode: LIGHT-ON/DARK-ON (switch-selectable)
Output type: NPN open collector
Control output: 30 V maximum, 100 mA maximum, residual voltage 1 V maximum
Supply voltage: 10 to 30 VDC nominal, ripple (P-P) 10%

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 sensor has no built-in ports or protocols, so it works as a standalone device without communication expansion.

Mechanical and Environmental Parameters

The housing uses glass-fiber reinforced PBT for durability, and the lens cover is polyarylate (PAR). Besides, the sensor weighs approximately 10 g, which reduces load on small mounting brackets. The rectangular body mounts through a dedicated hole with 0.5 N·m maximum torque.

Housing material: Glass-fiber reinforced PBT
Lens cover material: Polyarylate (PAR)
Weight: Approx. 10 g
Mounting torque: 0.5 N·m maximum (mounting 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-G101CN performs reliably in vibrating machinery and outdoor installations.

Installation Guide

First, mount the PZ-G101CN through the mounting hole and tighten to 0.5 N·m maximum. Over-tightening may crack the glass-fiber reinforced PBT housing. Keep the narrow sensing axis aligned with the target to use the small spot effectively.

Next, connect the M8 connector cable, which is sold separately. Wire the supply voltage within 10 to 30 VDC and observe the polarity markings. The NPN open collector output connects directly to standard PLC input cards. Confirm the output load stays below 100 mA and 30 V.

Then, adjust the 1-turn trimmer to set sensitivity for the target material. For instance, small or low-reflectivity targets may need a closer mounting distance. Use the green stable operation LED to confirm reliable detection and the orange output LED to monitor switching status.

Finally, keep ambient light below the rated limits. Avoid direct sunlight above 20,000 lux and incandescent light above 5,000 lux. When two units operate side by side, enable the automatic different frequency function or fit polarization filters to prevent interference.

FAQ

Q1: What is the detection distance of the PZ-G101CN?
A: The sensor detects targets at up to 200 mm (7.87 in). Detection range varies with target size, color, and surface finish.

Q2: What spot size does the PZ-G101CN produce?
A: It produces an approximate 5 mm diameter spot at a 100 mm detecting distance. This narrow view suits small-part detection and edge positioning.

Q3: What output type does the PZ-G101CN provide?
A: It provides an NPN open collector output rated at 30 V and 100 mA maximum. This output matches standard PLC input cards without extra interface modules.

Q4: Does the PZ-G101CN come with a cable?
A: No. The sensor uses an M8 connector, and the cable is sold separately. Confirm the pinout and cable length before ordering.

Q5: Can the PZ-G101CN 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.
