HF42F-024-2HST Medium Power Relay 24VDC DPST 5A PCB Relay

The HF42F-024-2HST relay from Hongfa is a medium-power PCB relay designed for reliable switching in industrial control systems, automation equipment, power distribution circuits, and general electronic applications. Featuring a Form 2A (DPST-NO) contact configuration, it enables simultaneous switching of two independent circuits, making it suitable for dual-channel control designs.

This model operates with a 24VDC coil rated at 1.08k and consumes approximately 530mW of coil power. It provides stable and efficient actuation for PCB-mounted applications, ensuring consistent switching performance in industrial and commercial environments.

The HF42F-024-2HST supports switching loads up to 5A at 250VAC or 30VDC, making it suitable for lighting systems, HVAC controls, small motor circuits, power supplies, and embedded control modules. Its standard-size vertical PCB layout allows straightforward integration into control boards where dual-circuit switching is required.

Constructed with Ag contact material, the relay ensures good conductivity and long operational life under repetitive switching conditions. With a 4kV isolation voltage between coil and contacts, it provides strong dielectric protection and improved safety in electrically noisy environments. The relay is certified to UL, CUR, TUV, and CCEE standards, ensuring compliance with international safety and reliability requirements.
