HF115F-L-12-HS3L2TF 12V DC 16A Latching PCB Relay Form 1A

The HF115F-L-12-HS3L2TF(335) is a high-power miniature sealed low-profile latching relay designed for efficient high-current switching in industrial, automation, and power management applications. Its compact dual-coil latching structure minimizes continuous power consumption while delivering reliable switching performance for demanding electrical loads.

This relay features a Form 1A (SPST-NO) contact configuration, providing a normally open high-current switching output ideal for power control circuits, smart energy systems, and industrial equipment. The dual-coil latching mechanism uses separate SET and RESET coils, allowing the relay to maintain its switching state without continuous coil energization, improving overall energy efficiency.

Operating from a 12V DC supply with a 240 coil resistance, the relay delivers stable and dependable operation in low-voltage control systems. It supports switching loads up to 16A at 250VAC, with peak capabilities up to 440VAC / 300VDC depending on load conditions, making it suitable for heavy-duty applications requiring reliable power switching.

The sealed low-profile housing protects the internal contacts from dust, flux contamination, and environmental exposure, ensuring long-term reliability and stable performance. With a low height of only 15.7mm, the relay is ideal for compact PCB layouts and space-constrained designs.

Enhanced safety features include reinforced insulation, 5kV dielectric strength between coil and contacts, and creepage distances up to 11mm, meeting stringent VDE and IEC 60335-1 safety requirements for high-voltage operation.
