ProTechTrader SRC-9VDC-SH DPDT 9 V DC relay

SKU CH-0NYD-3K739 MPN SRC-9VDC-SH

A 9 V DC DPDT relay with gold-clad silver contacts, 0.2 W coil power, 1 A switching capacity and standard 8-pin PCB mounting

  • Low 0.2 W coil draw keeps circuits efficient
  • DPDT 2 Form C gold-clad contacts switch reliably
  • 1 A max load handles typical signal tasks
  • 8-pin PCB through-hole mount fits standard 5.1 mm × 7.6 mm spacing
  • 8 ms operate / 5 ms release for responsive switching

Purpose and Audience

This ProTechTrader SRC-9VDC-SH relay is a 9 V DC DPDT component designed for low-signal switching on printed circuit boards. It suits hobbyists, students and engineers building DIY electronics or prototyping with platforms such as Arduino.

Decisive Specification

The relay uses bifurcated cross-bar gold-clad silver contacts rated for a maximum current load of 1 amp with 8 ms operation and 5 ms release times. Its coil draws 0.2 W at 405 ohms resistance, requiring a 9 V DC nominal supply to actuate reliably.

Sustained Load Behaviour

Low coil power consumption of 0.2 W limits heat generation during continuous energisation, supporting stable operation in long-running circuits. The non-latching, non-polarised design returns to the default state cleanly when power is removed, avoiding contact weld or residual magnetism issues.

Highlights

  • Low 0.2 W coil draw keeps circuits efficient
  • DPDT 2 Form C gold-clad contacts switch reliably
  • 1 A max load handles typical signal tasks
  • 8-pin PCB through-hole mount fits standard 5.1 mm × 7.6 mm spacing
  • 8 ms operate / 5 ms release for responsive switching

Questions about this item

What does the 1 amp rating mean when the relay is switching a load?

The contacts are rated to carry up to 1 amp of current at the load side.

How does the 5.1 mm by 7.6 mm pin spacing affect board compatibility?

The pins match a standard DIP-2C footprint and fit a 16-pin IC socket.

What hole size and board thickness suit the through-hole pins?

The pins are designed for standard PCB through-hole mounting with 5.1 mm by 7.6 mm spacing.
