Ampere Turns is one of the factors that provides an efficient solenoid. The ampere-turn (AT) is the unit of magnetomotive force, represented by a direct current of one ampere flowing in a single-turn loop in a vacuum.
Example: The ampere-turns for a coil with 1000 turns and a 500 mA current.
N = 1000 turns and I = 500 mA
N = 1000 turns and I = 0.5
NI = 1000 x 0.5
= 5 At
*Magnetomotive force is any physical cause that produces magnet flux.
The application form is designed to provide the information required to assess an application.

Set of normally open and set of normally closed contactor.
The aperture usually found in the top cover housing is sealed to form a barrier to assist prevention of airborne contamination into the contact area.
Vacuum impregnated coils are available to safeguard against shock and vibration and / or high humidity.
Coil termination is typically via 6.3mm faston spade termination. Flying leads, M5 studs and other termination are available.
