SRD-9VDC-SL-C Relay 9V DC Coil, 10A, SPDT, 220VAC, 5 Pin

SRD-9VDC-SL-C Relay 9V DC Coil, 10A, SPDT, 220VAC, 5 Pin

Product Overview

The YC3F-DC9V-SHC from Pro Tronix is a versatile, industry-standard miniature power relay. It is specifically designed for projects where a 9V DC power source (such as a 9V battery or a regulated 9V supply) is used to trigger the switching of high-voltage appliances.

As an SPDT (Single Pole Double Throw) relay, it features both Normally Open (NO) and Normally Closed (NC) contacts, allowing you to control whether a circuit is completed or broken when the coil is energized. Its compact 5-pin “Sugar Cube” footprint makes it easy to integrate into custom PCBs for smart home modules, security systems, and industrial controllers.

Technical Specifications

Key Features

• Universal 9V Coil: Optimized for 9V systems, ensuring reliable latching without the need for additional voltage converters in 9V-based designs.

• High Switching Capacity: Despite its small size, it safely manages loads up to 10A, suitable for fans, lights, and small motors.

• SPDT Versatility: Offers both NO and NC terminals, giving you full flexibility to design “fail-safe” or “always-on” logic.

• Durable Construction: Built with high-quality silver alloy contacts for a long mechanical and electrical life.

Common Applications

• Battery-Powered Automation: Ideal for portable devices where a 9V battery is the primary power source.

• Smart Home Modules: Toggling 220V AC lamps or small appliances via a wireless 9V control signal.

• Security Systems: Triggering sirens, door locks, or alarm strobes when a sensor is tripped.

• HVAC Control: Acting as an intermediary switch for thermostats or ventilation fans.
