General Mach Discussion / AKZ250 BREAKOUT BOARD - NPN NO PROXIMITY SENSORS
« on: October 22, 2018, 01:40:07 PM »
Hello Gents
I have built a cnc router from a kit and the X,Y and Z- Axis is working. Now I want to connect the NPN type Normally Open proximity sensors to the AKZ250 BOB.
The power supply is 24V DC and I am aware that a resistor must be installed, to reduce the voltage, between the sensor and the BOB.
The confusing part is, the way to wire the NPN proximity sensor, as per the AKZ250 User Manual.
This BOB is shown on YouTube and also how to wire the NPN sensor to it.
There are 3 wires on the sensor. BROWN, BLUE and BLACK.
BROWN = +
BLUE = - (GND)
BLACK = SIGNAL to BOB
The AKZ250 User Manual states that a RESISTOR must be installed between the BROWN+ and the BLUE (SIGNAL) and the BLACK wire goes to GND. The YouTube video shows a resistor connected between the BLACK wire (Signal) and the port on the BOB.
I don`t want to do something wrong here, which could cause the BOB to be damaged.
Any advice would be really appreciated.
Regards
Craig
