Active signal relay for AC load switching
The Panasonic AQH1213AX is an active-production signal relay from the AQ-H series, configured as a single-pole single-throw normally-open (SPST-NO) switch with zero-cross AC output. Rated for 600 mA continuous load current across a 0 V to 600 V AC range, it handles line-voltage signals in control and instrumentation circuits where galvanic isolation is needed.
Package and board-fit details
Housed in an 8-SMD package (0.300" body width, 7.62 mm pitch, 7 leads) with gull-wing terminations, the relay suits standard surface-mount assembly processes. Supplied in tape-and-reel format for automated pick-and-place; the 1.21 VDC input threshold allows direct drive from low-voltage logic or microcontroller GPIO without a separate driver stage.
