Why Choose the Carlo Gavazzi S142BRNN024 Photoelectric Amplifier?
The Carlo Gavazzi S142BRNN024 is a single-channel photoelectric sensor amplifier designed for use with compatible separate through-beam photoelectric sensors in industrial automation and machine-control applications. Part of the Carlo Gavazzi S142 series, it combines an SPDT changeover relay with NPN transistor output functionality, adjustable sensitivity and an integrated timer for flexible object-detection control.
The S142BRNN024 supports through-beam sensing systems with an operating range of up to 50,000 mm (50 m), depending on the connected emitter and receiver. Adjustable sensitivity, diagnostic functions and alignment assistance help simplify sensor setup and commissioning, while selectable light-on and dark-on operation enables the switching logic to be matched to the application.
Operating from a nominal 24 V AC supply, the S142BRNN024 features an SPDT relay output plus NPN output, alarm functionality and adjustable time-delay operation. Its compact rectangular plastic housing and 11-pole plug-in connection make it well suited to industrial control panels and machinery requiring reliable long-range photoelectric detection.

Reliable Timed Photoelectric Detection for Industrial Automation
Separate-amplifier through-beam photoelectric systems use an emitter and receiver positioned opposite one another, with the amplifier monitoring the received optical signal. When an object interrupts the beam, the amplifier changes its output state, providing dependable presence detection over considerably longer distances than many self-contained photoelectric sensors.
The Carlo Gavazzi S142BRNN024 adds adjustable time-delay control, sensitivity adjustment, diagnostic functions and alignment assistance to this sensing arrangement. Its combination of an SPDT relay and NPN transistor output enables integration with a wide range of industrial control equipment, while the timer is particularly useful where output activation or release must be delayed to suit the machine sequence.
Typical Applications
- Conveyor product and object detection.
- Packaging and production machinery.
- Long-range through-beam sensing systems.
- Material handling and logistics equipment.
- Timed presence and position detection.
- Industrial doors and access-control systems.
- OEM automation and machine-building applications.
