Overview of the parts for the single hall sensor detector module. There is also a small cap added to shield the whole. With 2 small pins/holes the cap fits just on the housing. I use the servo type 3x0.17mm² colored wire for the connection. The chip is internally protected for wrong polarity. If you connect incorrectly, it will not work but it won't break anything.
The standard 3 pole female connector fits perfectly in the housing. Inside are 2 twisted wires (GND,VCC) to get the same connection to the connector as servos are connected. GND, VCC, Output. The 9V from the TXT Controller fit perfect, the output is open collector type and may be connected directly to the controller input.
