Frequently asked questions
What is the price of HRS1KH-S-DC12V Signal Relay SPDT 12VDC Coil 1A 5-Pin Through-Hole in Egypt?
HRS1KH-S-DC12V Signal Relay SPDT 12VDC Coil 1A 5-Pin Through-Hole currently costs 15 EGP in Egypt.
Where can I buy HRS1KH-S-DC12V Signal Relay SPDT 12VDC Coil 1A 5-Pin Through-Hole in Egypt?
HRS1KH-S-DC12V Signal Relay SPDT 12VDC Coil 1A 5-Pin Through-Hole is available from Makers Electronics. Compare the offers above to find the best price.
Can I drive this relay directly from an Arduino pin?
Not recommended. At 12V the coil draws about 17mA (12V ÷ 720Ω), so use an NPN transistor or relay driver module, and add a flyback diode across the coil to protect the driver.
What is the difference between the 12V and 6V versions?
The coil voltage and coil resistance differ. The 12V version has a 720Ω coil, while the 6V version (HRS1KH-S-DC6V) has a 180Ω coil. Choose the version that matches your coil supply voltage.
