Two sealed DC T73 electromagnetic relays, normally open, supplied as a 2 piece package. This compact relay is designed for DC switching and comes in coil voltage variants of 3V, 5V, 12V, 24V and 48V. The relays are sealed to protect the contacts from dust and moisture, enabling reliable operation in a range of environments. With a small form factor and a normally open configuration, they provide a simple and safe way to control DC loads from a low voltage control signal. Key benefits Sealed construction for protection against dust, moisture and contaminants, increasing durability in varied environments. Normally Open (NO) configuration: the load remains off until the coil is energized, giving clear control behavior. Compact, small form factor suitable for tight spaces and PCB mounting in compact electronic or control projects. Wide coil voltage options (3V, 5V, 12V, 24V, 48V) to match the control circuit supply and logic level. Two relays per package (2PC), offering installation convenience and flexibility for paired or multiplechannel switching. Model is T73, a proven design intended for robust DC switching applications. Key attributes Functionality: DC electromagnetic relay with normally open contact configuration. Compatibility: Coils available in multiple DC voltages (3V/5V/12V/24V/48V) to suit common control electronics. Size: Small, compact form factor suitable for spaceconstrained designs. Material: Sealed housing protecting internal contacts from environmental exposure. Performance: DC switching relay designed for reliable operation in standard control and automation tasks. Package contents: 2 relays per (2PC). Use cases DIY and microcontroller projects: Use to switch small DC loads such as motors, solenoids, or LED drivers from a lowvoltage control signal, with electrical isolation between control logic and the load. Home automation and control panels: Integrate in panels to galvanically isolate and control devices like lights, fans, or sensoractuated equipment from the control circuitry. Laboratory or industrial control setups: Employ in experiments or automation systems where reliable DC load switching and isolation are required, while fitting into compact or tightly spaced layouts. Notes for selection and use Choose the coil voltage variant that matches your control supply (3V, 5V, 12V, 24V, or 48V). Verify that the load current and voltage requirements are within the relay's rating for your application. The product is provided as a 2piece package; ensure you have sufficient quantity for your design or project. This description stays true to the product's brand, model, and features: 2PC sealed DC T73 electromagnetic relays with normally open contacts, available in standard DC coil voltages, designed for compact and reliable DC switching in a sealed package.
