Photodiode Amplifier Connect
Photodiode Amplifier Connect – Compact Signal Conditioning Interface for UV, Visible and Infrared Photodiode Sensors
The Photodiode Amplifier Connect is a compact plug-and-measure signal conditioning module designed for precise current-to-voltage conversion of photodiode outputs.
Developed by SGLUX, it provides an efficient interface between UV, VIS, or IR photodiodes and downstream electronic systems such as data loggers, controllers, or Digiboards.
Its pre-calibrated transimpedance amplifier ensures low-noise operation, high linearity, and stable output across a wide dynamic range.
The integrated connector housing simplifies mechanical and electrical installation — no soldering or external circuitry required.
Ideal for OEM integration, laboratory setups, and process monitoring, the Photodiode Amplifier Connect delivers accurate signal amplification with NIST/PTB traceable calibration.
It is fully compatible with SGLUX SiC, GaP, and Si photodiodes, forming the perfect modular building block for UV measurement, radiometric calibration, and optical process control systems.
Understanding Photodiode Amplifier Connect
The Photodiode Amplifier Connect functions as an inline transimpedance amplifier, converting photocurrents generated by UV or optical detectors into proportional voltage signals.
Its compact design integrates both the amplifier and connector in one housing, enabling direct connection to SGLUX mounted photodiodes or sensor heads.
Factory-calibrated gain resistors and temperature-stable components ensure long-term reproducibility and minimal drift.
Users can easily interface the amplifier with external displays, data loggers, or PLCs without requiring specialised electronics knowledge.
With its plug-and-play design and traceable performance, it provides a reliable foundation for precision UV sensing and industrial automation.
