HF115F-048-1ZS2A Miniatur High Power Relay 48V DC 12A Low Profile PCB Relay

• The HF115F-048-1ZS2A is a compact, high-reliability miniature power relay designed for medium-to-high voltage control applications in industrial systems, automation equipment, and PCB-based electronic assemblies. It combines a space-efficient low-profile design with strong electrical performance, making it suitable for applications where higher coil voltage and reliable load switching are required.
• This relay uses a Form 1C (SPDT) contact configuration, enabling it to switch between normally open and normally closed states using a single control input. It is driven by a 48V DC coil with a resistance of 5.76k , providing stable operation while keeping coil power consumption at approximately 400mW.
• With a maximum switching capacity of 12A at 250VAC, the HF115F-048-1ZS2A is suitable for controlling motors, industrial loads, power distribution circuits, and automation equipment. -It's higher coil voltage makes it ideal for systems already operating on 48V control rails, reducing the need for additional voltage conversion stages.
• The relay is built in a sealed, low-profile housing that protects internal contacts from dust, flux, and environmental contamination, improving durability and long-term switching reliability. - A 10mm creepage distance and 5kV isolation voltage between coil and contacts ensure strong electrical safety and resistance to high-voltage transients.

Its compact footprint (approximately 29.0 × 12.7 × 15.7 mm) and PCB termination make it suitable for high-density circuit layouts where space efficiency is critical. The relay is also designed in compliance with UL, CUR, VDE, and FIMK approvals, ensuring suitability for international safety and industrial standards.
