I purchased the Pepperl+Fuchs REF-H85-2 square reflector (PN 55289321). It fits perfectly with our photoelectric sensor, has high reflectivity and stable performance. The size is accurate and durable for industrial workshop use. Very satisfied with the quality.

We’ve installed the NBN3-F31K-Z8-K on our pneumatic actuator stations for over a year, and it’s been totally reliable. The 3 mm sensing range is spot-on for detecting small metal targets, with consistent accuracy and almost no hysteresis. Its IP67-rated PBT housing handles oil, dust and occasional water splashes without issues—ideal for our factory floor. The sensor’s compact block design mounts directly to standard actuators, saving time and brackets. Two yellow LEDs clearly show sensor and valve status, making troubleshooting a breeze. With 6–60 V DC wide voltage input, 500 Hz switching frequency, and -25°C to 70°C working range, it fits most industrial setups. Reverse polarity protection is a nice safety touch. A solid, well-built sensor worth the investment.

We’ve been using the Pepperl+Fuchs SJ3,5-G-N slot sensor for 6 months in our automated assembly line, and it has exceeded expectations. The 3.5 mm narrow slot width delivers precise detection for small metal parts, with zero false triggers even at high speedsPepperl+Fuchs. Its IP67-rated PBT housing stands up to dust, moisture, and minor industrial debris—perfect for our harsh workshop environmentPepperl+Fuchs. The sensor is compact (15×10×19.5 mm, only 10 g), making installation a breeze in confined spacesPepperl+Fuchs. The NAMUR output ensures seamless integration with our safety control system, and the -25°C to 100°C temperature range lets it run reliably in both cold storage and high-heat production zones. While the price is slightly higher than generic alternatives, the 3000 Hz fast switching frequency and long-term durability make it a cost-effective choicePepperl+Fuchs. Highly recommend for industrial automation and safety-critical applications!
