Sensor Pinout Specification

Pinout definitions for our popular sensors
	British Telecom Analog (BTA)- Right Hand Pin 1 = Sensor output (+/-10V) Pin 2 = GND Pin 3 = Vres (resistance reference) Pin 4 = AutoIDENT (not supported on all sensors) Pin 5 = Power (+5VDC) Pin 6 = Sensor output (0-5V) BTA Cable Information Yellow = Sensor output (± 10V) Black = GND Green = Vres (resistance reference) Brown = AutoIDENT Orange = +5VDC Red = Sensor output (0-5V)

British Telecom Digital (BTD)- Left Hand

	Circular DIN Plug - 5 pin Pin 1 = Sensor Output Pin 2 = Not used Pin 3 = ID Output (not supported on all sensors) Pin 4 = Power (+5VDC) Pin 5 = GND

	Circular DIN Plug - 8 pin Pin 1 = Sensor Output Pin 2 = Not used Pin 3 = ID Output (not supported on all sensors) Pin 4 = Power (+5VDC) Pin 5 = GND Pin 6 = +12VDC Pin 7 = -12VDC Pin 8 = DAC
	1/4" Stereo Jack
