SENSOR
The AR1100 Touch Screen Controller Board supports 4, 5 and 8-wire sensors. A 2x8 
pin header (“SENSOR”) seen in the mechanical diagram is the connection point for all 
3 sensor types. Additionally, a 4-conductor flat flex connector can be used with 4-wire 
sensors. An illustration of sensor wiring/construction is given below for reference (see 
Figure 2-5).
