PROFINET enhances productivity, efficiency, and flexibility in industrial processes empowering smarter, faster, and more reliable automation.

IP rating

IP20

    An IP20 rating means an electrical product has limited protection against solid objects, specifically solids larger than 12mm (like fingers), but offers no protection against water

Housing material

PPE (Polyphenylene Ether) – High-Performance Thermoplastic
PPE is a heat-resistant, dimensionally stable, and electrically insulating thermoplastic ideal for demanding applications. Commonly used in automotive components, electrical housings, and medical devices, it offers strength, low moisture absorption, and excellent resistance to water and chemicals—perfect for harsh or high-temperature environments.

Power Connection

Terminal type

Electrical Terminal – Reliable Connection Point
       A terminal, also known as a terminal block, is a metal component enclosed in a durable plastic casing that serves as a reusable endpoint for electrical conductors. It provides secure and reliable connections for circuits, making it an essential accessory in industrial and electrical applications.

Transmission rate

        A 100 Mbps (megabits per second) transmission rate means 100 million bits of data move across a network connection every second

Signal type

       Digital- A digital signal is a discrete signal representing data as a sequence of distinct, stepped values, typically binary (0s and 1s), unlike continuous analog signals. It uses finite voltage levels (e.g., high for '1', low for '0') to convey information, making it robust against noise and ideal for computers, telecommunications, and data processing.
