Frequently Asked Questions

What does DPDT mean and how many circuits can this relay control?

DPDT stands for Double Pole Double Throw, meaning this relay has two independent changeover contacts (2 CO configuration). Each contact can switch between two positions, allowing you to control two separate circuits or create complex switching logic. With the 8-pin configuration, you have access to both normally open and normally closed contacts for maximum flexibility.

Can this relay be used with AC loads or is it DC only?

While this relay has a 24V DC coil, the 2A AgNi + Au contacts can switch both AC and DC loads up to the rated current. However, DC loads are typically more demanding on contacts due to arc suppression challenges, so the actual switching capacity may vary depending on the load type and voltage being switched.

What does "wash tight (RT III)" protection mean for PCB assembly?

RT III wash tight protection means the relay is sealed against flux cleaning solvents and ultrasonic cleaning processes used in professional PCB assembly. This prevents contamination of the internal contacts and coil, ensuring reliable operation after the board has been through standard manufacturing cleaning procedures.

How do I identify the pin connections on this 8-pin DIL relay?

This 8-pin subminiature relay follows standard DIL (Dual Inline Package) pinout conventions. The pins are numbered 1-8 with pin 1 typically marked by a dot or notch on the relay body. The coil connections and contact arrangements follow Finder's standard 30 Series pinout, but you should consult the technical datasheet for the exact pin assignments to ensure correct wiring.

What's the difference between this subminiature relay and standard PCB relays?

The main difference is size - at just 10mm width, this subminiature relay takes up significantly less PCB space than standard relays while still providing 2A switching capacity. The trade-off is typically in contact life and maximum switching current compared to larger relays, but the compact design makes it ideal for high-density applications where space is more critical than maximum power handling.
