Balluff BES01AU Inductive Proximity Sensor

Description

The Balluff BES 516-324-G-S49-C, also known as BES01AU, is a high-quality inductive sensor designed for reliable detection of metallic objects in industrial environments. Its compact M8 threaded housing allows for easy and flush installation, even in space-constrained applications. This sensor operates on a 10 to 30V DC supply and provides a PNP normally open (NO) output, ensuring compatibility with standard PLC inputs.

FAQ

What does "flush mountable" mean for this sensor?

Flush mountable means the sensing face of the BES 516-324-G-S49-C can be installed level with the surrounding metal mounting surface without affecting its performance. This is ideal for applications where space is limited or the sensor needs to be protected.

The standard 3-pin M8 connector for this PNP sensor is pinned as follows: Pin 1 is for the positive supply (+V, typically brown wire), Pin 3 is for the ground (0V, typically blue wire), and Pin 4 is the signal output (typically black wire).

Yes, as an inductive sensor, it can detect all metals. However, the nominal sensing distance of 2 mm is specified for standard steel targets. For non-ferrous metals like aluminum, the sensing distance will be reduced due to a correction factor. You should consult the Balluff datasheet for the specific reduction factor for your target material.
