Keyence PZ-G61CP Photoelectric Sensor PNP

Product Introduction

The Keyence PZ-G61CP is a built-in amplifier photoelectric sensor designed for long-range retro-reflective detection. This rectangular unit includes the P.R.O. function, which improves performance in challenging environments. Furthermore, its compact housing suits tight mounting spaces on production lines.

Because the sensor reaches up to 4.2 m with the R-2L reflector, it handles wide conveyor and pallet detection tasks. Besides its long range, the unit responds in 500 µs or less for high-speed sorting. Therefore, it serves packaging, material handling, and logistics applications reliably.

Technical Specifications

Detection and Optical Performance

The PZ-G61CP operates as a retro-reflective sensor with a long-range design. Its detecting distance spans 0.1 to 4.2 m when paired with the R-2L reflector. Moreover, a red LED serves as the light source for stable detection.

Sensitivity and Response

A 1-turn trimmer (230°) allows straightforward sensitivity adjustment. Meanwhile, the response time stays at 500 µs maximum for fast switching. In addition, the operation mode supports LIGHT-ON/DARK-ON selection via a switch.

Indicators and Output

Two LEDs report status clearly. Specifically, an orange LED shows output state, while a green LED confirms stable operation. The output uses a PNP open collector configuration rated at 30 V maximum, 100 mA maximum, with residual voltage of 1 V maximum.

Electrical and Environmental Parameters

Power and Protection Circuits

The sensor accepts a supply voltage of 10 to 30 VDC nominal, including 10% ripple (P-P) . Current consumption stays at 34 mA or less. Additionally, built-in protection covers reversed polarity, overcurrent, and surge events.

Interference Suppression

Up to 2 units can operate side by side without interference. This relies on polarization filters or the automatic different frequency function. Consequently, dense sensor arrays remain reliable.

Environmental Durability

The PZ-G61CP carries a protection rating of IEC IP67 / NEMA 4A, 6, 12 / DIN IP69K. Its operating temperature range extends from -20 to +55 °C without freezing. Moreover, it withstands ambient light up to 5,000 lux from incandescent lamps and 20,000 lux from sunlight.

Mechanical Strength

Vibration resistance follows 10 to 55 Hz, double amplitude 1.5 mm, for 2 hours on each axis. Shock resistance reaches 1,000 m/s², applied 6 times per axis. The housing uses glass-fiber reinforced PBT, and the lens cover is polyarylate (PAR) .

Installation Guide

1. Reflector Setup: Mount the R-2L reflector directly opposite the sensor to achieve the full 4.2 m detecting distance.

2. Mounting Torque: Tighten the mounting hole part to 0.5 N·m maximum to avoid housing damage.

3. Sensitivity Adjustment: Turn the 1-turn trimmer (230°) slowly while monitoring the green stability LED.

4. Mode Selection: Set LIGHT-ON or DARK-ON according to your control logic before commissioning.

5. Cable Connection: Use the M8 connector for quick, sealed wiring in washdown areas.
