Sick GRTE18-P1162 Photoelectric Sensor

The GRTE18-P1162 from Sick features a robust cylindrical housing with a diameter of M18 x 1 and dimensions of 18 mm x 18 mm x 71.5 mm, making it highly adaptable to space-constrained installations. Its axial optical axis and potentiometer-based adjustment allow precise alignment and sensitivity control. Built with nickel-plated brass and ABS, and sealed to an IP67 rating, this sensor withstands tough industrial environments including dust, moisture, and mechanical stress.

Using a visible red light LED source with a wavelength of 650 nm, the GRTE18-P1162 provides a focused light spot of Ø 45 mm at 800 mm, ensuring accurate detection of objects within a range of 10 mm to 800 mm (maximum sensing distance up to 1,000 mm). The sensor supports light/dark switching with PNP output, operates on 10 V DC to 30 V DC with low 30 mA current consumption, and delivers fast switching at 500 Hz with a response time under 1,000 µs. It connects via a reliable 4-wire, 2-meter cable and includes LED indicators for quick status checks.

This photoelectric proximity sensor is a trusted choice across industries due to its combination of durability, precision, and ease of integration. Whether used in automated conveyors, packaging machines, or robotics, the GRTE18-P1162 consistently delivers high-speed, error-free detection performance.

The Sick WL4S-3F2130 Photoelectric Sensor is widely used in real-world applications such as bottle detection on conveyor belts, label sensing on transparent films, and object counting in fast-moving assembly lines. Its ability to detect light or dark targets with minimal background interference makes it highly effective in environments where conventional sensors often fail.

For junior engineers and technicians, the sensor’s ease of installation and simple configuration using indicator LEDs and plug-and-play wiring offers a smooth learning curve. It performs reliably even in areas with dust, oil mist, or ambient light variation—factors that typically affect sensing accuracy. Maintenance teams appreciate the sensor’s consistency, as it requires minimal recalibration once installed, helping avoid production delays.

Senior maintenance engineers often choose the WL4S-3F2130 in applications where reliable sensing without false positives is critical to system performance and safety. Its compact form factor fits easily into small machines, while the fast response time ensures it doesn’t miss even high-speed object changes. This sensor helps improve operational efficiency, reduce manual inspection, and maintain product quality across varied industries like packaging, pharmaceuticals, and electronics.
