Cynex Systems

At Cynex System, we develop sensor and actuator interface solutions that enable embedded control systems to interact effectively with the physical world. Sensors provide information about operating conditions, while actuators perform physical actions in response to control signals. Proper interfacing ensures that these devices communicate effectively with electronic controllers and operate according to application requirements. Our approach focuses on signal conditioning, actuator control, and reliable system integration. Whether your application requires accurate sensor measurements, electronic control of motors and other devices, or integration with an existing PCB, we aim to develop interface solutions tailored to your technical needs.

Sensor Signal Conditioning and Acquisition

We design sensor interface circuits that prepare electrical signals for processing by microcontrollers and embedded control systems. Depending on the sensor and application, this can involve signal amplification, filtering, voltage scaling, and analog-to-digital conversion. These functions help ensure that sensor outputs are compatible with the controller's input requirements. We also consider measurement range, signal noise, electrical characteristics, and operating conditions when developing sensor interfaces. By addressing these factors, we aim to support reliable data acquisition and provide the controller with usable information for monitoring, measurement, and control functions.

Our capabilities can include:

Analog and digital sensor interfacing.
Signal amplification, filtering, and conditioning.
Voltage conversion and measurement interfaces.
Sensor integration with microcontrollers and embedded boards.

Actuator Drive and Control Interfaces

Actuators convert electrical signals into physical actions, including movement, switching, and mechanical operation. We develop electronic interface circuits that allow embedded controllers to operate compatible actuators according to the requirements of the application. Depending on the device, the interface may require transistor-based drivers, relay circuits, motor drivers, or pulse-width modulation (PWM) control. We consider voltage, current, switching requirements, and appropriate electrical protection to ensure that the interface is suited to both the controller and the connected actuator.

Our capabilities can include:

Relay and transistor-based switching circuits.
Motor, solenoid, and other actuator interfaces.
PWM-based control where appropriate.
Driver circuit design and electrical protection.

Electrical Protection and Signal Reliability

Sensor and actuator interfaces must operate reliably under the electrical conditions of their intended application. At Cynex System, we consider potential challenges such as voltage fluctuations, electrical noise, current overloads, and transient disturbances when designing interface circuits. Appropriate protection and filtering techniques can help safeguard connected electronics and maintain stable signal behavior. Depending on the application, interface designs may incorporate current limiting, transient voltage suppression, filtering, or electrical isolation. Selecting suitable protection methods requires consideration of the connected devices, circuit characteristics, and operating environment.

Our capabilities can include:

Input and output protection circuit design.
Electrical noise filtering and signal stabilization.
Overcurrent and transient protection.
Electrical isolation where required.
Interface reliability improvements.

Custom Interface PCB Design and Integration

We develop custom interface PCB solutions that connect sensors, actuators, and embedded controllers within a unified electronic system. By integrating the required interface circuits onto a dedicated board, we can help simplify wiring, organize connections, and accommodate the electrical requirements of different devices. The design can include connectors, signal conditioning circuits, actuator drivers, power interfaces, and communication connections according to the application. We also consider board dimensions, component placement, electrical compatibility, and accessibility to support practical integration into the final equipment.

Our capabilities can include:

Custom PCB design for sensor and actuator interfaces.
Integration of connectors and interface circuitry.
Combined sensor input and actuator output boards.
Adaptation of interface boards to existing controllers.
Design refinement for compactness and maintainability.

Every sensor and actuator has unique electrical and functional requirements. At Cynex System, we aim to develop interface solutions that connect these devices effectively with your embedded electronics, supporting accurate measurements, appropriate control, and coordinated system operation.
