Describe：

A small medium-power DC relay with ultra-thin PCB installation design, featuring a set of normally open contacts (SPST-NO), 24V DC coil voltage. This device is a small power relay of the HF49FD series, with a plastic-sealed package. The contact switching capacity is up to 5A, and the dielectric withstand voltage between the contacts and the coil is 3kV, meeting the enhanced insulation requirements of IEC61131-2. The coil power consumption is approximately 0.12W - 0.18W, the action time is ≤ 10ms, and the release time is ≤ 5ms. The creepage distance and air distance are greater than 3.5mm (typical value 4.2mm), and the insulation resistance is 1000MΩ. It has a printed board-type lead-out terminal, 4 pins, and DIP packaging. The size is 20mm × 5mm × 12.5mm, and the weight is approximately 3g. The contact material is AgNi or AgSnO2. The operating temperature range is -40°C to +85°C. It complies with RoHS environmental standards and passes safety certifications such as UL, TUV, and CQC.
