Schrack 12V 4 Pin Relay - HE3321A1200
Relay is a mechanical switching unit that can be controlled electrically. It consists of two main parts: relay coil and contactors. The relay coil, passing current, creates a magnetic field and attracts the contacts. Thus, relay contacts change position.
It is one of the circuit components preferred in telecom applications, gas detector circuits, RF control applications, Infrared control applications, small volume circuits (gum relay) etc.
It is used in the control of load currents between 1A-40A at operating voltages of 5V, 9V, 12V, 24V, 48V, 220V. Single and multiple contact output possibilities are available.
