s142bnnt230 – photo amp 1ch 2npn timer
Carlo Gavazzi S142BNNT230 is a single-channel 230 V AC photoelectric amplifier for through-beam sensors with two NPN outputs, adjustable sensitivity, LIGHT-ON and DARK-ON operation, diagnostic functions, test input and an integrated timer.
Why Choose the Carlo Gavazzi S142BNNT230 Photoelectric Amplifier?
The Carlo Gavazzi S142BNNT230 is a single-channel photoelectric amplifier with two NPN outputs and integrated timer functionality, designed for use with compatible through-beam photoelectric sensor heads in industrial machinery and automation systems. As part of the Carlo Gavazzi S142 series, it provides adjustable sensitivity, diagnostic functions and alignment assistance for dependable long-range object detection.
Designed for through-beam sensing applications, the S142BNNT230 supports detection ranges of up to 50,000 mm (50 m) with compatible sensor heads. Adjustable sensitivity allows the sensing system to be optimised for the installation, while diagnostic and alignment functions assist engineers during commissioning, troubleshooting and routine maintenance.
The amplifier operates from a nominal 230 V AC supply, with a specified operating supply range of 195–265 V AC, and provides two NPN transistor outputs. Integrated timer functionality, LIGHT-ON and DARK-ON operating modes, a test input and an 11-pole plug connection make the S142BNNT230 a flexible solution for industrial photoelectric sensing and machine-control applications.

Reliable Long-Range Photoelectric Signal Processing
A separate photoelectric amplifier processes signals from compatible optical sensor heads and converts the detected beam condition into switching signals for an industrial control system. Through-beam sensing places the emitter and receiver on opposite sides of the detection area, allowing reliable object detection over substantially longer distances than many self-contained photoelectric sensing arrangements.
The Carlo Gavazzi S142BNNT230 combines long-range sensing support with adjustable sensitivity, LIGHT-ON and DARK-ON operation, diagnostic assistance and an integrated timer. These functions allow machine builders and automation engineers to configure the sensing response for specific processes while the two NPN outputs provide interfaces for compatible PLC and machine-control circuits.
Typical Applications
- Long-range through-beam object detection.
- Industrial conveyor and material handling systems.
- Packaging and production machinery.
- Automated manufacturing and assembly equipment.
- Presence and position monitoring.
- Warehouse and logistics automation.
- Timed detection and machine-control sequences.
- PLC-based industrial automation systems.
