The HF115F-A-230-1ZS3AF is a high-performance miniature sealed PCB relay designed for reliable switching in demanding industrial and automation applications. Featuring a low-profile compact design, it delivers strong load-handling capability while maintaining excellent electrical isolation and long-term durability.

This relay uses a Form 1C (SPDT) contact configuration, allowing a single control input to switch between normally open and normally closed outputs. It operates with a 230V AC coil and a coil resistance of 32.5k , making it suitable for direct integration into high-voltage AC control circuits without additional driving components.

With an enhanced switching capacity of up to 16A at 250VAC, this model is well suited for heavier electrical loads such as motors, HVAC systems, pumps, industrial machinery, and power distribution control circuits. Its robust contact system ensures stable operation even under frequent switching conditions.

The relay is fully sealed in a durable plastic housing, protecting internal components from dust, flux, and environmental contamination during PCB assembly and operation. A reinforced insulation design with 10mm creepage distance and 5kV dielectric strength ensures safe operation in high-voltage environments.

Its compact footprint of 29.0 × 12.7 × 15.7 mm allows efficient PCB layout integration, making it ideal for high-density electronic designs where space and reliability are both critical.
