New development of coils with outer metal reinforcement
Coils with integrated circuitry give maximum protection of control electronics
ATAM, a leading company in the field of encapsulated coils and industrial connections, has chosen Hannover Messe 2022 for the launch of a renewed range of coils with outer metal reinforcement.
Especially suited to severe hydraulic applications, the coils with outer metal reinforcement are now available with integrated electronic components, undertaking the important task of dampening voltage peaks; high intensity transients that can create unclean signals which may generate disturbances towards the control electronics, causing potential damage. To this end, ATAM uses transils, which are easy to integrate into the coil thanks to their small size and ability to dampen overvoltages bidirectionally (both the positive and negative waves of alternating current).
The coils with outer reinforcement offered by ATAM are the series 471, 472 and 473, in the 3 external diameters of 37 mm, 45 mm and 65 mm and with electrical connections DIN – DEUTSCH – AMP JT. All products are distinguished by an outer metal reinforcement that serves to maximise the magnetic flux, and therefore the force generated. The offer is complete, in terms of dimensions and connections, allowing the customer to turn to a single supplier for the different needs of their machines.
ATAM’s coils with outer reinforcement are characterised by an excellent linear behaviour that makes them ideal for applications on proportional solenoid valves, whose main feature is to exert a constant force for a wide range of travel, with a contained hysteresis.
ATAM is able to offer coils with external reinforcement for applications on proportional solenoid valves together with a dedicated actuator developed by ITALMAGNETI, a partner company in ATAM Group, thus ensuring maximum performance thanks to the perfect integration of the two products.
The family of coils with outer reinforcement has been designed to be used in hydraulic applications in which high performance is required as well as resistance to severe demanding conditions, characterised by extreme temperatures and strong stresses. Therefore, they prove to be perfect in machines used in the agricultural and construction world, where they also meet the strict specifications of the OEMs relating to environmental tests or stress tests, often more stringent than those required by the reference standards of the sector. The coils with outer reinforcement are guaranteed to resist in salt spray up to 120h for white rust and up to 360h for red rust; they are also encapsulated in a high-quality thermoplastic material, which guarantees a Class H thermal resistance, for maximum operating temperatures up to 180°C.
ATAM’s tailor made
ATAM’s coils with outer reinforcement can be completely customised, with ATAM able to develop products with specific dimensions or connections and different treatments of the outer reinforcement. The result is therefore a very varied offer, also the result of the company’s ability to find the ideal solution for any given application. Over the years, ATAM has become an expert in a variety of customer operating environments, appreciating where the coils and solenoid valves will operate and thus being able to offer all-round consultancy to guarantee a functionality and security of the coil-solenoid valve unit, that is difficult to match.
New configurations for ATAM overmoulded connectors
Available with IP69K protection degree, the range can be configured with different
electronic circuits and also supplied with an output connector for plug-in installations
ATAM, specialist in the field of encapsulated coils and industrial connections for pneumatic and hydraulic applications, launches its expanded range of overmoulded connectors for solenoid valves at Hannover Messe 2022.
The newly available configurations can employ control circuits offering additional functions such as visual indication of correct operation, protection against overvoltage and transformation from alternating current to direct current. Furthermore, the terminal part of the cable can provide configurations with other connectors, such as Y-shaped for split commands, enabling faster and safer wiring.
The control circuits used by ATAM are assembled on PCB in compliance with a high quality standard, assembled on the various types of contact carriers and subsequently overmoulded.
The LED configuration provides immediate visual feedback on real time voltage status, and therefore on the correct functioning of the solenoid valve. The construction for this configuration includes a transparent plastic shell to protect the components and diffuse LED brightness. The varistor or transil has the function of damping the voltage peaks that may occur when the coil is de-energised, protecting both the load and the control electronics, thus ensuring a longer life to the system. Finally, the rectifier bridge is entrusted with the task of transforming the current from alternating to direct.
Customisations such as integrated identification labels and external recognition pad printing for circuit and voltage identification are also available for the overmoulded connectors developed by ATAM. Finally, ATAM also guarantees a wide selection of ex-stock cable types for overmoulding, as well as the potential to use special cables for specific requests, in order to offer maximum customisation.
The connectors for overmoulded solenoid valves offered by ATAM are all characterised by an IP69K protection degree, and are available in the five configurations of the DIN standard. These differ in their pitch between 8 mm and 18 mm, for use that ranges from mobile applications, to automotive, robotics, and on hydraulic, pneumatic and process valves.
The technical synergy in the development and production of encapsulated coils and industrial connectors and the availability of a latest generation test laboratory allow ATAM to simulate the combined use of the two products, in all conditions, thus being able to offer customers optimal solutions in terms of reliability, quality and convenience. This flexibility is completed with the availability of both standard plug-in options (with circular connectors) and fully customised.
