The nero ultrasonic sensors

are a compact series with M18 threaded sleeves and only 41 mm in housing length. In addition to the variants with an axial beam direction, there is also a housing variant with a 90° angled head and radial beam direction.

With four detection ranges from 20 mm to 1.3 m and three different output stages, this sensor family covers a wide range of applications.

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 seconds

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 seconds

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.
