Keyence PZ-G101CP Photoelectric Sensor
Product Introduction
The PZ-G101CP belongs to the Keyence PZ-G series, a widely used line of built-in amplifier photoelectric sensors. This specific model is a diffuse reflective sensor with a narrow view design. It detects objects without needing a separate reflector. The sensing distance reaches up to 200 mm, making it suitable for medium-range detection tasks on production lines.
Engineers and maintenance teams value the PZ-G101CP for its practical adjustment features. A single-turn trimmer allows quick sensitivity tuning across a 230-degree range. The sensor also provides switch-selectable LIGHT-ON or DARK-ON operation modes. This flexibility simplifies integration into existing control systems. Additionally, the M8 connector design speeds up replacement and reduces downtime during maintenance.
The sensor ships with an instruction manual. For connector-type models like this one, the mating cable is sold separately. Users should prepare a compatible M8 cable before installation. Furthermore, the compact rectangular housing fits into tight spaces where larger sensors cannot be mounted.
Technical Specifications
The PZ-G101CP operates on a supply voltage of 10 to 30 VDC with a ripple tolerance of 10% peak-to-peak. Current consumption stays at 34 mA or less, which keeps power demands low. The control output is a PNP open collector type. It handles a maximum of 30 V and 100 mA, with residual voltage capped at 1 V.
Key electrical parameters:
Supply Voltage: 10 to 30 VDC (including ripple)
Current Consumption: 34 mA or less
Output Type: PNP open collector
Response Time: 500 µs maximum
Control Output: 30 V / 100 mA max
Optical performance centers on a red LED light source. The spot diameter is approximately 5 mm at a detection distance of 100 mm. Sensitivity adjustment uses a 1-turn trimmer with a 230-degree range. Operation mode is switchable between LIGHT-ON and DARK-ON. Two LED indicators provide status feedback: orange for output and green for stable operation.
Mechanical and Environmental Parameters
The housing uses glass-fiber reinforced PBT, while the lens cover is made of polyarylate (PAR). These materials resist impact and chemical exposure in typical factory settings. The mounting hole accepts a maximum tightening torque of 0.5 N·m, which prevents over-tightening damage during installation.
Environmental ratings:
Protection Rating: IP67 / NEMA 4A, 6, 12 / IP69K
Operating Temperature: -20 to +55 °C (no freezing)
Relative Humidity: 35 to 85 % RH (no condensation)
Ambient Light Resistance: 5,000 lux (incandescent) / 20,000 lux (sunlight)
Vibration Resistance: 10 to 55 Hz, 1.5 mm double amplitude
Shock Resistance: 1,000 m/s², 6 times per axis
Interference suppression supports up to 2 units when the automatic different frequency function is active. The sensor weighs approximately 10 g for the connector model. Its compact size and light weight reduce mechanical stress on mounting brackets.
Installation Guide
First, mount the PZ-G101CP using the rectangular housing's mounting holes. Apply a torque of no more than 0.5 N·m to avoid cracking the PBT housing. The sensor should face the target material squarely. A tilted angle can reduce detection reliability and shift the effective sensing distance.
Next, connect an M8 connector cable to the sensor's built-in port. The cable is not included, so confirm the pinout and wiring match the PNP output configuration. Route the cable away from high-voltage lines and moving machinery. Additionally, secure the cable with ties to prevent strain on the connector.
After wiring, power the sensor and observe the green stability indicator. Adjust the sensitivity trimmer with a small screwdriver until the orange output LED responds correctly to target presence. Test the setup with sample targets at the expected detection distance. Finally, verify the LIGHT-ON or DARK-ON setting matches the control system logic.
Packaging List
Note: M8 connector cable is sold separately. Certificates and warranty documents are not included.
FAQ
Q1: What is the maximum detection distance of the PZ-G101CP?
The sensor detects targets up to 200 mm away when sensitivity is set to maximum. This distance applies to standard white paper targets.
Q2: Does this model include a cable?
No. The PZ-G101CP uses an M8 connector, and the mating cable must be ordered separately. Confirm the cable pinout matches the PNP output type.
Q3: Can I use the PZ-G101CP in wet environments?
Yes. The sensor carries an IP69K rating along with NEMA 4A, 6, and 12 approvals. It resists water spray and dust ingress in washdown areas.
Q4: How do I switch between LIGHT-ON and DARK-ON?
A switch on the sensor body selects the operation mode. Refer to the instruction manual for the exact switch location and orientation.
Q5: What is the response time of this sensor?
The PZ-G101CP responds within 500 µs maximum. This speed suits most conveyor and assembly line detection tasks.
