HF115F-A-024-2ZS4AF Mini 24V AC 8A Sealed PCB Relay 2C Low Profile

The HF115F-A-024-2ZS4AF is a compact, high-performance miniature sealed relay designed for dual-channel switching in industrial control, automation, and power management applications. Built with a low-profile PCB-mount design, it delivers reliable operation in space-constrained environments while maintaining strong electrical insulation and long-term durability.

This relay features a Form 2C (DPDT) contact configuration, providing two independent changeover circuits within a single device. It operates with a 24V AC coil and a resistance of 350 , ensuring stable activation in AC-driven control systems commonly used in industrial and building automation.

With a switching capacity of up to 8A at 250VAC (and peak ratings up to 440VAC / 300VDC depending on load conditions), the relay is suitable for moderate-power switching tasks such as signal routing, HVAC systems, control panels, and industrial automation equipment.

Its sealed construction protects internal components from dust, flux, and environmental contaminants, ensuring consistent performance and extended service life. The Class F insulation system, combined with reinforced dielectric strength, enhances thermal stability and electrical safety in demanding applications.

The compact 5mm contact spacing and low-profile 29 × 12.7 × 15.7 mm body make it ideal for high-density PCB layouts where reliability and space efficiency are both critical.
