COIL The coil is available in different sizes and with different electrical terminations. 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 200C according to IEC 317-8
-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). 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).

ARMATURE ASSY

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 Viton are available upon request. The armature assembly is designed for more than 106 cycles.

COMPLETE 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 armature assy is fixed to the valve body either by means of a M12x0.5 thread (thread version) or by a mounting plate with screws (flange mounting version).

Amisco doesn't supply the plate. The suggested interface dimensions of the valve body are shown below. Any change to the prescribed dimensions can effect th performances of the solenoid operator.
