HF115F-A-230-1ZS2AF Mini 230V AC 12A Sealed PCB Relay Form 1C

The HF115F-A-230-1ZS2AF is a compact, high-voltage miniature sealed PCB relay designed for reliable switching in industrial automation, control panels, and AC power systems. Its low-profile construction makes it ideal for space-constrained applications where dependable performance and strong electrical isolation are required.

This relay features a Form 1C (SPDT) contact configuration, providing a single changeover circuit for flexible switching between normally open and normally closed outputs. It operates with a 230V AC coil and a coil resistance of 32.5k , enabling direct use in high-voltage AC control environments without additional driving stages.

With a switching capacity of up to 12A at 250VAC (with peak capability up to 440VAC / 300VDC depending on load conditions), the relay is well suited for medium-power loads such as HVAC systems, industrial machinery, automation panels, and general-purpose switching circuits.

The sealed plastic housing protects internal contacts from dust, flux residue, and environmental contamination, ensuring long-term reliability and stable electrical performance. A reinforced insulation system with 10mm creepage distance and 5kV dielectric strength between coil and contacts enhances safety in high-voltage applications.

Its compact footprint of 29.0 × 12.7 × 15.7 mm allows efficient PCB layout integration while maintaining high switching performance and durability.
