HF115F-005-1ZS3A High Power Mini Sealed Relay 5V 16A SPDT

The HF115F-005-1ZS3A is a high-power miniature sealed relay designed for demanding PCB switching applications requiring higher current handling in a compact low-profile form factor. It features a Form 1C (SPDT) contact arrangement and is engineered for reliability, long electrical life, and robust industrial performance.

Detailed Description

This relay operates with a 5VDC coil rated at 62 resistance, drawing approximately 80.65mA of coil current. It provides fast and stable actuation with a maximum pickup voltage of 3.5VDC and a dropout voltage as low as 0.5VDC, ensuring reliable switching even in fluctuating control conditions.

The HF115F-005-1ZS3A supports a maximum switching current of 16A, with a switching capacity of up to 4kVA at 250VAC. It is also rated for 440VAC and 300VDC maximum switching voltages, making it suitable for both AC and DC high-power applications.

Designed for durability, it offers an electrical life of approximately 75,000 operations and a mechanical life of up to 10 million operations, ensuring long-term reliability in industrial environments.

The relay features a sealed low-profile housing (29 × 12.7 × 15.7 mm) with through-hole PCB mounting and 5mm contact spacing, providing strong insulation and safe high-voltage operation. It is rated for operation across a wide temperature range of -40 C to +85 C, making it suitable for harsh environments.

With insulation resistance of 1000M and maximum contact resistance of 100m , it ensures stable, low-loss performance. The SPDT configuration allows flexible circuit switching between normally open and normally closed outputs.
