Sick GRTE18S-P2317 Photoelectric Sensor

The Sick GRTE18S-P2317 Photoelectric Sensor uses the energetic sensing principle to detect objects within a sensing range of 5 mm to 100 mm, and a maximum limit of up to 115 mm. It emits a visible red light using a PinPoint LED with a wavelength of 650 nm, creating a focused light spot of Ø 8 mm at 100 mm. This design ensures high accuracy when detecting small or low-contrast items in close proximity.

Built with a rugged ABS plastic housing and PMMA optics, the GRTE18S-P2317 is designed for durability in demanding industrial conditions. The sensor body measures a compact 18 mm x 18 mm x 38.1 mm and includes a standard M18 x 1 cylindrical thread with axial light emission, making installation straightforward across most mounting configurations. The M12, 3-pin connector ensures plug-and-play integration with modern control systems.

Its electrical performance is tuned for efficiency, operating on 10 V DC to 30 V DC with low 30 mA current consumption. It supports PNP output in light switching mode, has a response time under 1,000 µs, and can handle switching frequencies up to 500 Hz. With an IP67 enclosure rating, it’s protected against dust and moisture, while the wide ambient temperature range of –25 °C to +55 °C ensures dependable operation in tough environments. For system integrators and automation engineers seeking a reliable sensor for precise object detection, the GRTE18S-P2317 stands out as a trusted choice.

The Sick Photoelectric Sensor WL4S-3F2130 is an efficient retro-reflective sensor used in automated systems to detect objects with or without clear surfaces. It’s commonly used in bottling, labeling, and packaging lines, where it ensures that products are correctly positioned or present before the next process begins.

Maintenance engineers find it easy to use thanks to its visible red light that allows for quick alignment. The sensor includes diagnostic LEDs that show power and switching status, making troubleshooting and daily maintenance simple and intuitive. With reliable object detection and minimal false triggers, it minimizes downtime and increases system efficiency.

For engineering students and junior technicians, this sensor provides a hands-on introduction to sensing concepts like retro-reflective technology, signal response, and light alignment. The WL4S-3F2130 is not just a component—it's a dependable, field-tested tool that enhances productivity in real-world automation environments.
