Description

The SF2-DC5V is an electronic component model in the product category of IC Chips. It features forced operation contacts, independent operation contacts, and a separated chamber structure. The forced operation contacts consist of 2 Form A, 2 Form B, 3 Form A, and 1 Form B contacts, ensuring a minimum contact gap of 0.5mm in case of contact welding. The independent operation contacts include 4 Form A and 4 Form B contacts, with each pair of contacts being free from the main armature and independent from each other. Therefore, if a N.O. pair of contacts are welded, the other 3 N.O. contacts remain unaffected and continue to operate properly. The separated chamber structure of the SF2-DC5V model prevents short circuits between contacts, which can be caused by springs welding or being damaged. Additionally, this model is UL/CSA, TÜV, and SEV approved.

Comparison

The SF2-DC5V model offers various advantages such as forced operation contacts that ensure a minimum contact gap even in case of contact welding. The independent operation contacts allow for a circuit to detect welding or revert to the original condition. The separated chamber structure prevents short circuits between contacts, enhancing safety. Additionally, this model is UL/CSA, TÜV, and SEV approved, guaranteeing its reliability and compliance with industry standards.

However, it is important to note that the SF2-DC5V model is currently pending UL/CSA and SEV certifications for SF3.
