Pepperl+Fuchs is an industrial sensor and explosion protection technology manufacturer whose products are used wherever reliable field signal conditioning, hazardous area isolation, and industrial detection are required. Pepperl+Fuchs hardware covers intrinsic safety barriers, signal conditioners, industrial sensors, fieldbus connectivity modules, and position measurement systems, and is deployed across process industries, manufacturing, and logistics environments with demanding electrical and environmental requirements. PLC Direct supplies Pepperl+Fuchs industrial automation hardware for customers sourcing replacement components and installed-base parts for existing Pepperl+Fuchs systems.

Why Choose Pepperl+Fuchs Industrial Automation Products

Pepperl+Fuchs is recognized for a hardware portfolio that addresses two distinct operational challenges: safe signal transmission between hazardous and non-hazardous areas, and reliable detection across industrial environments. The K-System and other Pepperl+Fuchs isolation and signal conditioning products are installed in process facilities worldwide where ATEX and IECEx regulatory requirements apply, and Pepperl+Fuchs sensor and fieldbus hardware is deployed across manufacturing and logistics environments requiring precise field-level detection.

Pepperl+Fuchs products are commonly installed in:

Oil and gas production facilities and refineries with ATEX- and IECEx-classified hazardous areas
Chemical and petrochemical plants requiring galvanic isolation between hazardous and safe-area circuits
Pharmaceutical manufacturing with hazardous area process instrumentation
Power generation and industrial utility facilities with process signal conditioning requirements
Automated warehouses and distribution centers using AGVs with optical position guidance
Discrete manufacturing with fieldbus I/O and industrial sensor infrastructure
Food and beverage processing environments with industrial detection requirements

This deployment across process and manufacturing industries reflects Pepperl+Fuchs's emphasis on products engineered for environments where electrical safety, signal integrity, and detection reliability cannot be compromised.

Pepperl+Fuchs Products and Solutions

Pepperl+Fuchs hardware at PLC Direct covers signal conditioners, isolation barriers, fieldbus I/O modules, and position measurement systems used in process and manufacturing automation. The collection focuses on hardware that supports the maintenance and lifecycle continuity of installed Pepperl+Fuchs systems.

Pepperl+Fuchs Product Families

KFD2 K-System Isolated Barriers and Signal Conditioners: The KFD2 series is part of the Pepperl+Fuchs K-System, a platform of DIN-rail-mounted isolation barriers and signal conditioners that provide galvanic isolation between field-side hazardous area signals and the control system in the safe area. KFD2 modules are certified to ATEX and IECEx standards for Zone 1 and Zone 2 hazardous area applications and support 4-20 mA, HART, thermocouple, RTD, and NAMUR process signals, with spring terminal DIN-rail mounting. Confirmed variants in the PLC Direct collection include the KFD2-SOT2-EX2 and KFD2-STC5-EX1.
PMI Position Measurement Systems: Optical position measurement systems for AGV guidance and conveyor tracking applications. The PMI14V-F112-U-V3, confirmed in the collection, uses DataMatrix code reading or camera-based guidance to provide precise position feedback for automated guided vehicles and conveyor tracking systems in intralogistics and manufacturing environments.
VBA Fieldbus Modules: VBA series fieldbus connectivity modules providing distributed I/O node connectivity for fieldbus-connected automation systems. Confirmed variants in the collection include the VBA-4E4E-G11-ZAJ-F, VBA-4E4A-KE5-ZEJQE2L, VBA-4EA3-KE-ZE, and VBA-4E4A-KE1-Z, covering multiple I/O and connection configurations.

Frequently Asked Questions

A K-System isolation barrier is a DIN-rail-mounted signal conditioner that provides galvanic isolation between a field instrument located in a hazardous area and the connected control system in the safe area. Galvanic isolation physically separates the two circuits, preventing fault energy from crossing the zone boundary. K-System barriers are required wherever 4-20 mA, HART, thermocouple, RTD, or NAMUR field signals must be transmitted from a Zone 1 or Zone 2 hazardous location to the safe-area control system in compliance with ATEX and IECEx requirements.

We carry Pepperl+Fuchs K-System signal conditioners and isolation barriers, position measurement systems, and fieldbus I/O modules. Available hardware includes KFD2 K-System modules (KFD2-SOT2-EX2 and KFD2-STC5-EX1) with ATEX/IECEx certification for hazardous area signal conditioning, the PMI14V-F112-U-V3 optical position measurement system, and VBA series fieldbus modules in multiple configurations. Contact us with your part number to check current availability.

KFD2 K-System modules are certified to ATEX and IECEx standards for field-side connection to instruments in Zone 1 and Zone 2 hazardous areas. These certifications confirm that the modules are approved for use in explosive atmospheres on the field side of the isolation barrier. The specific entity parameters and approval scope apply per individual part number. Always verify the certification documentation for the exact module being installed against the hazardous area classification of the installation.

Both are KFD2 K-System isolated barriers, but they handle different signal types and channel configurations. They are not interchangeable in an installed system. A replacement KFD2 module must match the exact installed part number to maintain the correct signal path, channel count, and hazardous area approval. Always order using the exact part number from the installed unit or the system documentation.

The Pepperl+Fuchs PMI series optical position measurement systems are used in AGV navigation and conveyor tracking applications. They read DataMatrix codes or use camera-based guidance to provide precise position data as a vehicle or product moves through an automated system. These devices are common in automated warehouse and distribution center environments where accurate, real-time position feedback is required to coordinate vehicle routing and conveyor system operations.
