Signal Relay SPDT BSZ5-SS-112L (1 Form C) 12VDC Coil 1A Through Hole 5 Pin

Signal Relay SPDT BSZ5-SS-112L (1 Form C) 12VDC Coil 1A Through Hole 5 Pin

The Signal Relay BSZ5-SS-112L is a compact, PCB-mount SPDT (1 Form C) signal relay engineered for low-power switching in tightly packed electronic assemblies. Housed in a plastic-sealed body, it combines a small footprint (≈15.5 × 10.6 × 11.5 mm) with reliable contact performance up to 1 A, making it suitable where board density and dependable switching are required. The relay’s coil is driven by 12 VDC in the specified variant, providing predictable electromagnetic actuation while keeping coil power consumption low.

Mechanically robust for its class, the BSZ5 features plated through-hole pins for secure soldered connections and a plastic insulation material selected for high temperature and chemical resistance. Contacts are made from an Ag-alloy to balance low contact resistance and durability. The sealed construction excludes dust and solder flux, helping maintain contact integrity over many cycles even in typical household-appliance environments.

Electrically the relay offers quick response (operate time ≤10 ms, release ≤5 ms) and strong dielectric isolation (1,000 VAC between coil and contacts). It endures mechanical and electrical stress with rated life expectancies (electrical ≈10⁵ ops at rated resistive load; mechanical ≈10⁷ ops no load) and is designed to withstand surges (1,500 V) and wide operating conditions (−30 to 70 °C, 5–85% RH). These characteristics combine to deliver consistent, long-term switching in appliances and control systems.
