nero ultrasonic proximity switches

are available in a M18 plastic sleeve. In addition to the axial beam direction variant, there is also a housing variant with a 90° angled head and radial beam direction.

The ultrasonic proximity switches detect contactless and reliable objects with four detection ranges from 20 mm to 1.3 m.

For the nero sensor family

there are 2 output stages and 4 detection ranges available:

	1 switching output with pnp or npn switching technology
	1 analogue output 4–20 mA or 0–10 V

Sensors with switching output have three operating modes:

• Single switching point
• Two-way reflective barrier
• Window mode

Teach-in of a single switching point

• Place object to be detected (1) at the desired distance
• Apply +U_B to pin 2 for about 3 seconds
• Then apply +U_B to pin 2 again for about 1 second

Teach-in of a switching point

Teach-in of a two-way reflective barrier

with a fixed reflector

• Apply +U_B to pin 2 for about 3 seconds
• Then apply +U_B to pin 2 again for about 10 seconds

Teach-in of a two-way reflective barrier

For configuration of a window

• Place object at the near edge of the window (1)
• Apply +U_B to pin 2 for about 3 seconds
• Then move the object to the far edge of the window (2)
• Then apply +U_B to pin 2 again for about 1 second

Teach-in of an analogue characteristic or a window with two switching points

NCC/NOC

and rising/falling analogue characteristic curve can also be set via pin 2.

One green and one yellow LED

indicate the state of the output and support microsonic Teach-in.
