Connecting the Package Sensor
Chapter 2 gives the information needed to select a retro-reflective
photo switch, and also lists the extension cable options.
The Adapter Module has a yellow stub cable with a Micro-Change
connector. The extension cable is connected to the Adapter Module’s
connector, and then to the connector on the sensor.
In case the sensor does not have a connector, the pinout is given in Table 4.A.
The package sensor must be able to operate using the +12V DC source
(pin 1) and not draw more than 100mA. The package detect sense line (pin 2)
must be able to sink 5mA at +12V DC.

If the laser is not ON, it could be because

• the symbol has already been decoded
The package sensor must go OFF then ON to trigger the decoder before a
new symbol can be decoded. Refer to the Enhanced Decoder user manual
(Publication No. 2755-833) for further details.
