ATAM’s cable entry connectors awarded with VDE certification

17 July 2018

ATAM is a leading manufacturer of both encapsulated and external armature coils, industrial connectors and sensors.

ATAM KA Connector

The range has been further strengthened by additional certifications for ATAM’s KA and KB cable entry connectors.

VDE (Verband Deutscher Elektrotechniker) – the highest authority in regulations for electrical technologies – has recently certified these connectors in compliance with the DIN EN 60529 (VDE 0470) standard.

ATAM has therefore become Italy’s first company to join an exclusive club of European companies that have obtained this prestigious certification, thanks to the high quality and reliability of products, which are globally used by major solenoid valve manufacturers. 

Having integrated the CNE line and heavily invested in products and production processes, ATAM can now offer a complete range of connectors for solenoid valves, which stand out also for the custom solutions developed with customers. ATAM connectors are also available with moulded cables. They are intended for various fields of application and are assembled on state-of-the-art production lines for both productivity and product quality check purposes.

The technical synergy between the development and production of encapsulated coils and industrial connectors and a state-of-the-art laboratory allow ATAM to simulate the combined suitability of the two products under any condition. This way, customers are sure to receive optimal solutions in terms of reliability, quality and affordability.

ATAM’s KA and KB connectors

ATAM KB Connector

KA and KB connectors stand out for their strong design and the enclosure’s housing, which facilitate faster and easier wiring operations. KA and KB connectors feature a one piece electrical contact made with automated and high productivity shearing moulds (15,000 workpieces/hour). State-of-the-art machines check the quality of the electric contact of every workpiece. Every connector comes with a contact provided with integrated mechanical protection between the fixing screw and the cable. This way, damage to the strands of the copper wires is avoided during cable installation. ATAM is the first company to have introduced this feature in the solenoid valve connector market. Moreover, the connectors are assembled on automatic lines with final optical control via cutting-edge video cameras to ensure the utmost quality of every workpiece, with a production capacity of 1 million connectors per month.

Both KA and KB lines include standard connectors and connectors manufactured with electronic control circuits to provide additional functions, such as LED visual indication, protection against overvoltage, rectifiers, etc. The KA-A3 series deserves special attention, as it is equipped with a PWM control circuit designed to activate solenoid valves while optimising energy consumption.

The KA-A3 connector controls the power, and thus the energy provided to the solenoid valve, maximising it when the solenoid valve has to overcome the magnetic and mechanical forces required to position the mobile core inside the valve, then reducing power to a subsequent stage, when full power is no longer necessary, preventing the solenoid valve from heating up. KA-A3 auto-adjusts the solenoid valve current based on the input voltage so for battery powered applications the load is reduced to prolong battery life. 

Besides the two VDE-approved lines, there is an additional series of KA connectors carrying the UL marking, which is required for applications in the North American market. These type of connectors are made with special flame retardant materials

ATAM’s KA and KB connectors are resistant to water and dust (protection rating = IP65) and, therefore, perfect for pneumatic and hydraulic applications.
