ef1801npas – fibre-optic,100mm.npn.no/nc. cable
Carlo Gavazzi EF1801NPAS is an M18 fibre-optic photoelectric sensor amplifier with a 10–40 V DC supply, NPN normally open and normally closed outputs, 120 Hz operating frequency and a 2 m cable connection.
Why Choose the Carlo Gavazzi EF1801NPAS Fibre-Optic Photoelectric Sensor?
The Carlo Gavazzi EF1801NPAS is an industrial fibre-optic photoelectric sensor amplifier designed for reliable object detection in machinery, manufacturing and automation applications. Part of Carlo Gavazzi's M18 metal photoelectric sensor range, it provides an NPN normally open and normally closed output and is designed for use with compatible fibre-optic sensing heads where space or access around the detection point is restricted.
Fibre-optic sensing allows the actual sensing point to be positioned away from the sensor electronics, making the EF1801NPAS particularly useful for detecting small objects, components and materials in confined areas. Its sensing distance depends on the fibre assembly selected, providing flexibility for different machine layouts and detection requirements.
The EF1801NPAS operates from a 10–40 V DC supply, supports a load current of up to 200 mA and has an operating frequency of 120 Hz. The cable-connected version uses a 2 m integral cable, while its nickel-plated brass M18 housing and IP67 protection provide durability for industrial environments.

Reliable Fibre-Optic Detection for Industrial Automation
Fibre-optic photoelectric sensing separates the sensing point from the electronic amplifier by transmitting light through optical fibres. This arrangement makes it possible to detect objects in confined spaces and machine locations where installing a conventional photoelectric sensor directly at the sensing point would be difficult.
The EF1801NPAS provides complementary NPN switching outputs for integration with PLCs and industrial control equipment. Its wide DC supply range, protected output circuitry and IP67 metal housing make it well suited to repetitive sensing duties in production machinery and automated equipment.
Typical Applications
- Small component and object detection.
- Packaging and production machinery.
- Assembly and automated manufacturing equipment.
- Detection in confined or difficult-to-access locations.
- Conveyor and material handling systems.
- OEM machinery and industrial automation systems.
