RelayGo relay coils

The coils are molded in polybutylene with fiberglass (130° C). Enamelled wires of Class F specification are used (155° C).
They are always verified, 100%, considering quality tolerances.
They are wound on automatic precision winding machines, with the number of turns and wire tension accurately regulated and monitored.
Coil resistance is measured at 20° C and is regulated within ± 10% of specified value. They can be reviewed in each model specification table.
RelayGo can produce every specific voltage coil our customers require meeting their specifications.

Minimum working voltage (pull in) this is the minimum voltage that must be supplied to the coil to ensure contacts change over and the relay is energized, below you will find pull in Voltages:

Working:        50 Hz                60 Hz
VAC 50 Hz relays 0,8xUn             0,85xUn
VAC 60 Hz relays 0,75xUn          0,8xUn
VDC relays 0,8xUn

Maximum release voltage (drop out) this is the maximum voltage at which the contacts change over and NO contacts close without any vibration. The values of voltage specified are those at or below which the relay must drop out.

VDC relays: ≥ 10% de Un
VAC relays: ≥ 15% de Un

The ambient temperature has an influence on the coil resistance and on its thermal dissipation capacity.
Blue curve represents the variations of the pull in voltage (% Un) in relation with the ambient temperature (T). Red curve indicates the maximum values of the voltage applied (Ub) to the coil in relation with the nominal voltage (Un) at the ambient temperature (T).
