HF115F-L-12-ZS3L1TF 12V DC 16A Latching PCB Relay Form 1C

The HF115F-L-12-ZS3L1TF(335) is a high-power miniature sealed low-profile latching relay engineered for efficient and reliable switching in industrial automation, smart control systems, and energy-saving applications. Its compact single-coil latching design minimizes continuous power consumption while delivering dependable high-current switching performance.

This relay features a Form 1C (SPDT) contact configuration, providing a single changeover contact that supports both normally open and normally closed switching operations. The single-coil latching mechanism allows the relay to maintain its last switching state without requiring constant coil power, making it ideal for energy-efficient control systems and battery-powered applications.

Operating with a 12V DC coil and 360 coil resistance, the relay ensures stable operation and low power consumption. It supports switching loads up to 16A at 250VAC, with higher maximum capabilities up to 440VAC / 300VDC depending on load conditions, making it suitable for demanding power control applications.

The relay's sealed low-profile housing protects internal components against dust, flux contamination, and environmental exposure, ensuring long service life and reliable operation. With a height of only 15.7mm, it is ideal for compact PCB layouts and high-density electronic assemblies.

For enhanced operational safety, the relay incorporates reinforced insulation, 5kV dielectric strength between coil and contacts, and creepage distances up to 11mm, meeting VDE 0700, 0631, and IEC 60335-1 safety requirements.
