AMISCO - Model EVI 7 S8 -22 mm 08 Solenoid System

COIL
The coil is available both in 22 mm and in 30 mm size for increased performances.Types, power and other characteristics are described in the following pages. All coils feature:

• heat resistant bobbin moulded with 30% glass filled thermoplastic polyester material
• class H wire 200°C according to IEC 317-13
• built-in magnetic yoke made by low carbon iron
• encapsulation with high quality specially designed glass filled nylon.

The use of other materials is possible upon special agreements. All coils are rated to class F and to IP 65 (with connector) or IP67 for the flying lead version. The coil is designed and constructed in accordance to EN 60204.1 and VDE 0580 and it is suitable for industrial ambient conditions. For use in special ambients with high humidity, please, take contact with Amisco. The coil is also in conformity with 94/9/EC ATEX for electrical apparatus of group II, category 3 (Ex nA II 3 GD T4 o T5).

OPERATOR
Plunger and core are made by a magnetic stainless steel specially designed for solenoid applications. The guide tube is made with brass (stainless steel is possible upon special agreement). The plunger is normally equipped with NBR rubber seals. Other materials like FKM are available upon request. The armature assembly is designed for more than 50x106 cycles.

COMPLETE SOLENOID OPERATOR
The coil is fastened to the plungerguide tube by means of a knurled nut for ease of change over without interrupting the pneumatic circuit.
The plungerguide tube is fixed to the valve body by means of a M12x0.5 thread. The suggested interface dimensions of the valve body are
shown on the right side. Any change to the prescribed dimensions can effect the performances of the solenoid operator.
