Power Supply

Supply voltage: + 6 V... + 30 V DC.
Max. supply current: see certificates from chapter 2.3.
For use in zone 2: see certificates from chapter 2.3.
The sensors of the A5S1...-n series may only be operated in hazardous area zone 2.
Current consumption: approx. 15 mA (one channel sensor) resp. 25 mA (two channel sensor),
plus load (can increase up to 60 mA with long transmission length and high signal frequency).
If power supply isn't provided by a BRAUN device, a PELV resp. SELV power supply has to be
used.
4.3

Signal Output

Rectangular pulses with constant high level and low level over the entire speed
Push-Pull amplified output. Maximum load 20 mA.
The signal output is short circuit proof and protected against polarity error.

Installation Dimensions

The sensors are available with different installation threads (D) metric, resp. inch, resp. inch with
NPT, and each with a number of different nominal lengths (L). This is the length from the front
surface of the sensor to the end of the mounting thread (see figures on chapter 7).
