HF33F-012-HSLTF Miniature Intermediate Power Relay 12VDC 5A PCB

The HF33F-012-HSLTF relay from Hongfa is a compact miniature intermediate power relay engineered for reliable switching in PCB-mounted control and automation systems. Featuring a Form 1A (SPST-NO) contact configuration, this relay is ideal for simple switching applications where compact size, low coil power consumption, and dependable operation are essential.

This model operates with a 12VDC sensitive coil rated at 720 , offering efficient performance with only 200mW coil power consumption. The sensitive coil design allows easy integration with low-power control electronics, PLC outputs, microcontrollers, and embedded systems while reducing energy usage in continuously operated equipment.

The relay supports a maximum switching current of 5A at 250VAC, making it suitable for switching moderate electrical loads including lighting systems, signal control, small motors, fans, solenoids, and appliance circuitry. Its AgCdO contact material provides reliable conductivity, good arc resistance, and long electrical life under repetitive switching conditions.

Built with a plastic-sealed enclosure, the HF33F-012-HSLTF offers protection against dust and contaminants, improving long-term reliability in industrial and commercial environments. It also features an 8mm creepage distance and 1kV isolation voltage, enhancing safety and insulation performance in compact electronic assemblies.
