The Sick GRL18S-F2331 Photoelectric Sensor employs a dual-lens retro-reflective detection principle with an axial optical axis, allowing for consistent detection over a sensing range of 0.06 m to 6 m, and up to 7.2 m when used with optimal reflectors. This sensor uses a bright visible red PinPoint LED with a 650 nm wavelength and delivers a sharp Γ 175 mm light spot at 7 m, making alignment easy and highly accurate even at long distances.
Housed in a standard M18 cylindrical metal body with nickel-plated brass and ABS components, this sensor is built for durability in rough plant conditions. It supports a standard 10 V to 30 V DC supply voltage, with a low 30 mA current consumption and delivers a PNP switching output in dark switching mode. The response time is under 500 Β΅s, and it supports a fast 1,000 Hz switching frequency, making it highly reliable for high-speed automated operations.
Its M12, 3-pin connector ensures secure wiring and fast installation. The IP67-rated enclosure protects against dust, moisture, and oil, allowing this sensor to operate reliably from β25 Β°C to +55 Β°C. With dual LED indicators for power and output, and supplied with fastening nuts for easy mounting, the GRL18S-F2331 is a go-to sensor for machine builders and automation integrators alike.
The Sick WL4S-3F2130 Photoelectric Sensor is widely used in fast-paced industrial setups that require compact sensing and reliable performance. In packaging lines, it confirms the presence of cartons before sealing, preventing errors and reducing product waste.
