5V 30A SPST Relay

SKU: REL-003 Manufacturer: TE Connectivity Mfg Part Number: T9AS1D12-5 Category: Tags: ,



This relay is a SPST-NO (single pole – single throw – normally open) with a contact rating of up to 30A. Typically these will be used in a special footprint on a circuit board (such as our Large Relay Breakout), but they can be made to fit into perfboards with a little creativity. The coil voltage is 5VDC, so applying ~5V across the coil pins will change the contact position of the relay. The contacts can handle a maximum of 30A and voltages up to 277VAC / 28VDC.
