HF115F-L-12-2ZS4L2TF 12V DC 8A Dual Coil Latching Relay 2C

The HF115F-L-12-2ZS4L2TF is a high-power miniature sealed low-profile latching relay engineered for reliable switching and energy-efficient operation in industrial, automation, and smart control applications. Its compact dual-coil latching design allows the relay to maintain its switching state without continuous power consumption, making it ideal for energy-sensitive systems.

This relay features a Form 2C (DPDT) contact configuration, providing two independent changeover contacts for versatile dual-channel switching. The dual-coil latching mechanism uses separate SET and RESET coils for precise and stable operation, improving control reliability in automation and remote switching applications.

Operating from a 12V DC supply with a 240 coil resistance, the relay delivers dependable switching performance while minimizing power usage and heat generation. It supports switching loads up to 8A at 250VAC, with maximum load capability up to 440VAC / 300VDC depending on application conditions.

Its sealed low-profile housing protects internal components from dust, flux contamination, and environmental exposure, ensuring long operational life and stable electrical performance. The relay also features reinforced insulation with up to 5kV dielectric strength and creepage distances of 11mm (NO) and 10mm (CO), meeting stringent VDE and IEC 60335-1 safety standards.

With a compact height of only 15.7mm, the HF115F-L-12-2ZS4L2TF is ideal for high-density PCB layouts where reliable latching control and space efficiency are critical.
