9402-12 signal relays, up to 2 amp Series
cotorelayReed relays with 12 VDC coil for various mountings
The 9402-12 series from Coto Technology is a lineup of reed relays designed to handle up to 2 amps, powered by 12VDC coils. These relays are commonly found in applications requiring isolation between high-voltage circuits and control electronics, such as in industrial automation, HVAC systems, and automotive electronics. Engineers often reach for these relays when they need reliable switching capabilities without the complexity of solid-state relays.
One practical benefit of the 9402-12 series is their flexibility in mounting options, which include through-hole and surface-mount configurations. This makes them versatile for both prototyping and production environments. Another useful feature is their ability to switch a wide range of loads, from small signals to higher current applications, making them a go-to choice for many projects. If you're working on a system that requires clean electrical isolation and stable switching performance, these relays are definitely worth considering.
