## Datasheet

📄 [Download PDF](https://novapart.co/datasheet/farnell:4168448/)

## **IRC40** 

## **Proximity inductive sensors with rectangular housing and 5 positions rotatable head** 

## **Benefits** 

- Sensing face mountable in 5 different positions 

- Easily adaptable to several application needs 

- Four corner LEDs to ensure visibility of the switching status and operation from any direction 

- Flush or non-flush mountable 

- Extended sensing ranges: 22mm (flush), 40mm (Non- 

- flush) 

- IP69K protection degree for a certified resistance to frequent high temperature and high pressure washing cycles 

- Antivalent output (NO+NC), NPN or PNP 

- Easy mounting system (included) for quick installation or replacement of the sensor 

- Wide operating temperature range from -25°C to +80°C 

## **Description** 

Inductive proximity sensors with 40 mm x 40 mm rectangular housings for use in harsh ambient conditions to detect metal objects without contact and wear-free. 

The sensors generate an electromagnetic field which interacts with the detected object and are characterized by a long service life and extreme ruggedness. 

The long sensing distance of up to 40 mm makes them particularly suitable also for use in conveyor systems, assuring a stable and reliable detection even in harsh environments, also thanks to the integrated advanced electronics which ensures optimal performance with temperature variations. 

## **Applications** 

- Non contact detection of metal objects in general position-sensing and presence-sensing in industrial applications 

- Conveyor systems, material handling and logistic, agriculture, escalators

## **Main functions** 

- Easy and quick mounting or replacement without the need of additional tools thanks to the plug-and-play mounting system 

- Rotating sensor head in 5 different positions allows maximum flexibility in all applications 

- Reliable and accurate detection in the whole extended temperature range, thanks to the integrated advanced microprocessor based electronics 

- Safer installation thanks to the long sensing range up to 40 mm 

- Reliable switching performance even in harsh environments with low and high temperature, and enclosure rating IP68 and IP69K 

- Sensor switching and operating status can be clearly seen from any directions thanks to the 4 corner LEDs 

- Integrated diagnostic functions with flashing LEDs in the event of short-circuit or overload

## **Correction factors** 

The specific operating distance Sn refers to defined measuring conditions. The following data have to be considered as general guidelines.

**Fe360:** Steel; **CrNi:** Chrome-nickel; **CuZn:** Brass; **Al:** Aluminium; **Cu:** Copper; **Sr:** Effective operating distance. 

The rated operating distance is reduced by the use of metals and alloys other than Fe360. The most important reduction factors for inductive proximity sensors are shown in the figure.
