HF115F-A-230-2ZS4AF Mini 230V AC 8A Sealed PCB Relay 2C Low Profile

The HF115F-A-230-2ZS4AF is a compact, high-voltage miniature sealed PCB relay designed for reliable dual-channel switching in industrial control, automation, and power management systems. Its low-profile construction makes it ideal for dense PCB layouts where space efficiency and electrical reliability are equally important.

This relay features a Form 2C (DPDT) contact configuration, providing two independent changeover circuits within a single device. It operates with a 230V AC coil and a coil resistance of 32.5k , enabling direct integration into high-voltage AC control circuits without the need for additional driver stages.

With a switching capacity of up to 8A at 250VAC (and higher peak ratings up to 440VAC / 300VDC depending on load conditions), this relay is suitable for moderate-load applications such as signal switching, HVAC controls, industrial automation systems, and general-purpose PCB switching.

The sealed plastic housing protects internal contacts from dust, flux residues, and environmental contamination, ensuring long-term stability and consistent electrical performance. A reinforced insulation design with 10mm creepage distance and 5kV dielectric strength between coil and contacts enhances operational safety in high-voltage environments.

The compact footprint of 29.0 × 12.7 × 15.7 mm allows efficient PCB integration while maintaining high reliability and strong switching performance.
