HF115F-L-12-ZS3L2TF 12V DC 16A Dual Coil Latching Relay

The HF115F-L-12-ZS3L2TF(335) is a high-power miniature sealed low-profile latching relay designed for efficient switching and long-term reliability in industrial automation, smart energy systems, and advanced control applications. Featuring a dual-coil latching mechanism, this relay maintains its switching position without continuous power, reducing energy consumption and heat generation in demanding systems.

This model uses a Form 1C (SPDT) contact configuration, providing a single changeover contact suitable for versatile switching applications. The dual-coil latching design uses separate SET and RESET coils for stable and precise operation, making it ideal for remote switching, automation systems, and energy-efficient electronic controls.

Operating with a 12V DC coil and 240 coil resistance, the relay provides dependable low-power actuation while supporting high-current loads up to 16A at 250VAC. It is also capable of handling higher maximum loads up to 440VAC / 300VDC depending on operating conditions and application requirements.

The compact low-profile housing, with a height of only 15.7mm, is ideal for space-constrained PCB designs. Its sealed construction protects internal contacts from dust, solder flux, and environmental contamination, ensuring long operational life and consistent electrical performance.

Enhanced insulation features include 5kV dielectric strength between coil and contacts, reinforced creepage distances of up to 11mm, and a UL Class F insulation system. The relay also complies with VDE 0700, 0631, and IEC 60335-1 safety standards, making it suitable for high-reliability industrial and commercial equipment.
