The AQH1213 is a Panasonic Electric Works signal relay from the AQ-H series, configured as SPST-NO (1 Form A) with an AC zero-cross output. It switches loads up to 600 mA across a 0 V to 600 V AC range, driven by a 1.21 VDC input — the zero-cross switching reduces inrush and EMI when closing into capacitive or lamp loads.
Housed in an 8-DIP (0.300", 7.62mm) through-hole package with 7 leads and PC pin termination — the standard DIP footprint keeps it compatible with socket or soldered assembly. Supplied in tube packaging; the through-hole form factor suits prototype runs and low-to-medium volume production without reflow profile constraints.
