Electromagnetic relays

design and technological changes Modernization of the design and manufacturing process The offer of Relpol S.A. has been extended by new electromagnetic relays R2N, R3N, R4N which are modernized versions of the relays R2, R3, R4 still available in the offer. The new relays are extinguished by a modern design, higher quality and high functionality. They are manufactured in a modernized technology. Major changes in the design of the relays: - improvement of the functionality of the mechanical indicator, - application of electronics in the SMD technology for the additional features L and D, - improvement...

design and technological changes Application of electronics made in the SMD technology Additional features – light indicator (LED diode) and the surge suppression element (diode) are located on the printed circuit board. The SMD technology (surface mounting of electronics) eliminates manual assembly of the elements and „moves away” the place of the board soldering as far as from the contacts as possible. The change of the position of the LED diode and optimization of the quality and intensity of its light provide certainty that the relay is in operation status when the LED is on. Improvement...
