The KFD2-UT2-EX1 is a high-performance isolated safety barrier designed for temperature measurement in hazardous industrial environments. As a core product in ’ safety instrumentation portfolio, it serves as a critical interface between field sensors (RTDs, thermocouples, potentiometers, or voltage sources) in explosive zones and control systems in safe areas. This single-channel barrier provides 3-port isolation (input/output/power) to prevent electrical hazards and ensure signal integrity, while converting sensor signals into linear 0/4-20mA outputs compatible with PLCs, DCS, and other industrial control devices.

  KFD2-UT2-EX1 - Isolated Temperature Transmitter Barrier (SIL 2)

Automation is our world. Perfect application solutions are our goal.

In 1945, against the backdrop of a war - torn world, Walter Pepperl and Ludwig Fuchs, driven by a strong sense of inventiveness, entrepreneurial foresight, and a deep - seated belief in self - reliance, established a humble radio workshop in Mannheim, Germany.


Their journey was filled with hands - on exploration. As they worked on various radio - related projects, the experiences they amassed became the fertile ground for new and innovative concepts. They took great pleasure in delving into the needs of their customers, constantly striving to develop products that could meet and exceed expectations.

I bought the Pepperl+Fuchs NCN8-18GM40-N0-10M proximity sensor, part number 55289269. The 10-meter fixed cable is exactly what I needed. The sensor works reliably without false triggering on our production line. The build quality is solid, installation was quick. Will reorder again.

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!
