12V DC 2A DPDT Relay

• Suits various circuits in the modelling and hobby market
• Pin terminals for easily soldered joints
• 2A switching capacity
• Designed for operation on a 12V power source
• Double pole double throw

Why use a standard relay?
This relay is perfect for use in home automation, modelling applications or hobbies. It can be mounted onto a PCB board and includes eight easily soldered pins. With its compact size, this relay can be fit into many projects and enclosures. The relay can be run off a 12V power supply.

What does double pole double throw (DPDT) mean?
A single pole has one common terminal that can be switched between an NO (normally open) terminal and an NC (normally closed) terminal. The double pole has two poles connected this way, so there are two NO contacts and two NC contacts. When the relay’s coil is not powered, the common connector will be linked to the NC connections. When the relay is powered, the common connector will be linked to the NO connection.

Why would I use a relay?
There are several advantages to using a relay. You may want to switch a high current to a lower current, for example controlling a mains operated device with a lower powered switch.
You can use a DPDT relay so that a circuit is connected in one way when there is no power, and another when the relay is activated - for example switching two lights on with a single switch or reversing motion on a DC motor.

are the coils of these type of relays polarized. as it would seem they are but it is not mentioned in any data sheet I have read. when the voltage is the wrong way around the coil will not activate will this damage or used as control

Asked by: tone
I can confirm these miniature relays and others similar are polarised which means the dc voltage flow has to be correct. this can be a useful feature for certain applications. looking at the front of the relay with the text readable the positive terminal is under the bottom left corner and the negative is under the top left corner. I have tested a relay for incorrect connection for a 30 minute period with the polarity reversed and this has no adverse effect to the device or its operation. less diodes needed.

The data sheet gives coil characteristic for standard and high sensitivity types. I need the high sensitivity for the lower coil current - are these standard or high?

Asked by: Bill
I belive this is the standard coil rating.

Is there a data sheet relating pin layout to the internal circuitry? Currently, one has to work it out oneself with a continuity tester. Ideally, all components would have associated data sheets available for download.
