PhotoMOS Relays
How Do PhotoMOS Relays Work?
The input pins of PhotoMOS relays are connected to a light emitting diode which emits infrared light as soon as it is energized. Below the LED is an optoelectronic component that switches the output transistors. The entire unit is molded in translucent resin, which ensures galvanic separation between input and output. PhotoMOS relays are used in the field of:
- Medical Devices
- Telecommunication
- Measurement and instrumentation
- Security devices
- Industrial control
Advantages of PhotoMOS Relays
- Low control current
- Extremely long product life
- Fast and no noise switching
- High vibration and shock resistance
- Small size
- Flexible mounting position
- THT and SMD versions for automatic assembly
