Operational Information
Magnetic latching is achieved by a specially designed magnetic core that makes it possible to maintain a substantial magnetic force of attraction after termination of the electrical pulse that energizes the core. There are no mechanical latches associated with this relay, nor permanent magnets. To restore the relay to its unoperated position, a short pulse of opposite and lower magnitude than the operate pulse is applied to the coil or a second concentric wound coil.
