HF33F 012ZS3 12VDC (33FC5V/12V/24V5A) Relay 5pins This HF33F 012ZS3 12VDC SPDT relay provides a reliable 12V control option for switching loads up to 5A. It is a 5pin device in the HF33F family with a SPDT configuration (common, normally open, normally closed) and is suitable for general electronics and automation applications. Key features and attributes Type: SPDT relay Pins: 5 pins Coil voltage: 12V DC Contact configuration: SPDT (Common, Normally Open, Normally Closed) Contact rating: 5A Model and variant: HF33F 012ZS3; variant 33FC5V/12V/24V5A Quantity per unit: 1 piece Use case suitability: generalpurpose switching for 12V systems in electronics, control panels, and automation Specific use cases Microcontrollerdriven lighting control: switch 12V LED strips or lamps from a microcontroller or PLC, providing electrical isolation between control logic and load. Small DC motor or actuator switching: operate a 12V DC motor or actuator (up to 5A) while keeping control circuitry isolated from power circuits. Control panel signaling and interlocking: route signals to other circuits or devices via the relay's normally open and normally closed contacts for simple automation tasks. This relay offers a compact, versatile solution for 12V control needs, with a clear SPDT contact arrangement and a reliable 5A switching capability.
