The HF115F-012-1ZS1AF is a compact, high-performance miniature power relay designed for reliable switching in industrial, automation, and electronic control applications. Manufactured by Hongfa, this relay combines a small footprint with high switching capability, making it ideal for PCB-mounted designs where space efficiency and electrical reliability are critical.

Featuring a Form 1C (SPDT) contact configuration, the relay supports flexible switching between normally open and normally closed contacts. With a 12V DC coil and low power consumption of 400mW, it is suitable for energy-efficient control circuits. The relay is capable of handling up to 12A switching current at 250VAC, making it suitable for controlling motors, lighting systems, home appliances, and industrial loads.

The HF115F series is designed with a sealed plastic housing and a low-profile structure, ensuring durability and protection against environmental factors. It offers a 10mm creepage distance and 5KV dielectric isolation voltage, providing excellent electrical safety and reliability in high-voltage switching environments.

Its PCB mounting design with 3.5mm pin pitch ensures easy integration into circuit boards, while the compact dimensions (29.0 × 12.7 × 15.7mm) make it suitable for dense electronic assemblies. The relay uses AgCdO contact material, known for its strong arc resistance and long operational life.

Certified with UL, CUR, VDE, and other international approvals, this relay meets global safety and performance standards, making it suitable for professional and industrial-grade applications.
