LED Indication - Discrete: SMS1105PKD

The SMS1105PKD is part of a series of advanced discrete signals from Topled Optoelectronics. This series includes a wide range of opto-couplers, suitable for a variety of applications. It is often referred to simply as ‘SMS’. SMS1105PKD is a high performance opto-coupler that can be used in applications such as consumer electronics, automotive, industrial control, telecommunications, military and aerospace. It provides reliable protection to devices from unpredictable conditions in the input/output connections while maintaining electrical isolation between input/output circuits.

Application Field

The LED indication of SMS1105PKD is suitable for a variety of applications in consumer electronics, automotive, industrial control, telecommunications, military and aerospace.It is ideally suited for digital ISDN telephone systems, for example, for indicating the activity states of digital systems, for controlling multiple lines, for automatic circuit switching and for signalling.It can also be used in appliance control, such as for remote switching of fans or pumps, for digital switching and measuring of motor speed and torque and in medical applications, such as for indicating the position of the patient in X-ray scanners.

Working Principle

The SMS1105PKD works on a simple principle. An opto-coupler is used to convert electrical signals into light signals. The LED light source inside the device emits a light beam when a certain amount of current is applied. When the light beam passes through an optical fibre, it is converted into a electrical signal.The LED indication of the SMS1105PKD uses a special optical fibre to relay the light signals from the LED source to the output. The LED produces a visible output when a predetermined amount of current is applied to the LED. This is often used as a trigger signal to activate other circuits.The LED indication of the device can also be used for control of a variety of devices, such as for indication of status or warning in an array of digital devices or circuits.

Conclusion

The SMS1105PKG is an advanced discrete signal and an excellent choice for digital ISDN telephone systems, for appliance control, for digital switching and measuring of motor speed and torque and in medical applications. It is a reliable product and provides reliable protection to devices from unpredictable conditions. The LED indication of it is suitable for signaling, and control of a variety of devices.
