HF46F-5-HS1T Mini Sealed Relay 5VDC SPST-NO 3A PCB Relay

Descriptuons:
- The HF46F-5-HS1T relay from Hongfa is a compact low-power mini sealed relay designed for reliable PCB switching in embedded systems, consumer electronics, industrial controls, and automation applications. Featuring a Form 1A (SPST-NO) contact configuration, it provides straightforward normally open switching for general-purpose load control.
- This model operates with a 5VDC coil rated at 125 , making it suitable for direct interfacing with low-voltage logic circuits, microcontrollers, and digital control systems. Its low coil resistance enables efficient actuation while maintaining stable switching performance in compact electronic designs.
- The HF46F-5-HS1T supports switching loads up to 3A at 250VAC or 30VDC, with a maximum rating of 5A depending on load conditions. This makes it suitable for small motors, lighting circuits, appliance control, signal switching, and general PCB-level power management.
- The relay is built with a sealed housing to protect internal contacts from dust, flux, and moisture contamination, improving reliability in manufacturing and long-term operation. Its AgSnO contact material ensures good conductivity, stable switching behavior, and improved resistance to arc wear under repetitive switching conditions.
