PFK series

PFK series

Product catalog summary
Overview: The document provides detailed technical specifications for the PFK series of M18 cylindrical inductive sensors designed for food and beverage applications. These sensors are characterized by their robust construction, high protection ratings, and suitability for harsh environments.
Specifications: The sensors are housed in AISI 316L stainless steel, offering IP67, IP68, and IP69K protection. They are available in standard and long-distance models, with options for NPN or PNP output logic. The sensors support both NO and NC output states and have a nominal sensing distance ranging from 5 mm to 12 mm, depending on the model.
Features: Key features include LED status indicators, complete protection against electrical damages, and availability of ATEX models for hazardous environments. The sensors are designed to withstand temperature ranges from -40°C to +80°C, with short exposure to 100°C during cleaning processes.
Models and Variants: The document lists various models with different sensing distances and output configurations. Models with extended temperature ranges are also available. Correction factors for different materials like steel, copper, aluminum, and brass are provided.
Technical Specifications: The sensors operate on a voltage range of 10-30 Vcc, with a maximum ripple content of ≤10%. They support a switching frequency of 15 kHz and have a power-on delay of 50 ms. The sensors are equipped with short-circuit, voltage reversal, and induction protection.
Installation and Connection: The document includes electrical diagrams for connections, specifying the wiring for PNP and NPN configurations. The sensors use M12 plugs with gold-plated pins for reliable connections.
Dimensions and Accessories: Detailed dimensions for the sensors and included accessories, such as metallic nuts, are provided. The sensors are designed for easy installation in various industrial settings.
