SLA-1（T90-1）Relay

The SLA-1 (T90-1) Relay breaks away from the conventional logic of "simple performance upgrades" and builds its core advantages by starting from the pain points of procurement practice: it innovatively provides 2000/4000VAC dual-level dielectric strength selection, eliminating the need for separate development or stocking for different safety level projects. One product covers both conventional and high-voltage scenarios, greatly reducing the capital tied up in inventory and inventory pressure; with three contact configurations (A/B/C) and sealed/open dual forms, there is "no customization waiting" from circuit design to working condition adaptation. The 5-48VDC wide nominal voltage is directly compatible with multiple power supply solutions, saving the cost of circuit adaptation and modification. More importantly, the product is readily available and supports bulk wholesale. The lightweight 24g body and standardized PCB installation not only simplify the assembly process and improve production efficiency, but also minimize the maintenance frequency of terminal equipment through the hardcore configuration of ≤100mΩ low contact resistance and 10⁵ electrical cycles, achieving worry-free operation throughout the entire "procurement-production-use" cycle.
