Solenoids

The electromagnets of the ER series are linear, single-acting, in which the movement of movement from the initial position to the end position is effected by electromagnetic forces and the return to the initial position is effected by external forces or by built-in spring to the electromagnet. The useful force is obtained from the magnetic force (Fm) by adding or subtracting the weight of the moving core. The values of the magnetic force (Fm) as a function of the stroke are obtained under the following conditions:

- Ambient temperature = 35ºC
- Coil stabilized at its working temperature
- Supply voltage equal to 90% of the nominal value
- Electromagnet in horizontal position

The arrangement of the connection terminals is what can be seen in the following picture. n request, they can be mounted in different positions and dimensions and the terminals can be replaced by free conductors.
