The FLUO SENS integrated features a 10way flex cable in the rear
part of the housing (see 4.1 and 4.2). This flex cable is used for
communication and power supply. Dimensions are shown left.
Flex cable type: MOLEX 98267-0257
Matching connector (SMD) MOLEX 52610-1071 (not included)
Pin assignment of the flex cable is shown in the table left. Note the
following:
*): These inputs do not provide internal pull up resistors. In normal
operation they should be tied to +5V/+3.3V.
**): The levels of the serial interface are with respect to the detector
type either ±6V (RS232), 0/+3.3V (TTL).
In the TTL-version the TxD-signal (pin 3) is disconnected when not
used for data transmission. So, multiple devices can be connected in
parallel. All devices will receive data simultaneously, activate the TxD
pin and respond only if the modbus address matches.
All ground return pins should be connected to achieve optimal quality
measurement results.
