Frequently asked questions
What is the price of Fujitsu SY-18-K Mini Signal Relay SPDT 18VDC 1A 6-Pin in Egypt?
Fujitsu SY-18-K Mini Signal Relay SPDT 18VDC 1A 6-Pin currently costs 25 EGP in Egypt.
Where can I buy Fujitsu SY-18-K Mini Signal Relay SPDT 18VDC 1A 6-Pin in Egypt?
Fujitsu SY-18-K Mini Signal Relay SPDT 18VDC 1A 6-Pin is available from Makers Electronics. Compare the offers above to find the best price.
Can a microcontroller pin drive it directly?
No. The 18 V coil needs 18 V and draws about 9 mA (18 V divided by 1940 Ω), which a 3.3 V or 5 V GPIO cannot energise. Use a transistor driver from a suitable supply, with a flyback diode across the coil.
Is it suitable for mains loads?
It is rated as a signal relay at 1 A and 60VA / 24W. For mains-connected loads, choose a relay whose power rating matches the load and the mains voltage.
