Accurate time.
Consistent operation.
GPS synchronisation provides a common time reference. Supported clock models use TCXO real-time clock technology with battery-backed timekeeping between synchronisation updates.

About UsOptoElectronics.LK
Practical engineering. Dependable displays.
We design and manufacture GPS-synchronised clocks and industrial LED display systems in Sri Lanka, combining clear information with serviceable construction.
What we build
Information that works
where you work.
A clock across a factory floor. A production count above a line. An alarm that keeps a shift on schedule.
OptoElectronics.LK makes equipment for practical timing, counting and information needs. Our core range focuses on GPS-synchronised clocks and large numeric LED displays, supported by selected industrial control and wireless systems.
Our work brings together electronics, PIC firmware, display control and enclosure construction. The application determines the digit size, control method and communication interface.
We value high-grade components, clear visibility and equipment that can be maintained over its working life.
Our engineering priorities
Built with the whole system in mind.
Accurate time.
Electronics and firmware
working together.
From register-level PIC development through embedded C, we configure the control logic around the application. Selected systems use isolated PLC inputs, dedicated remotes and LoRa RF communication.
Designed to be repaired.
Supported after delivery.
Serviceability includes the electronics, display and enclosure. Repairable construction and direct technical support help keep equipment useful beyond installation.
