MA-100 Backpack (5-pin LEMO - 004 connector option)

LEM connector

The MA-100 system uses a 5-pin LEMO p/n FGG0B305CLAD31Z plug with a GMA0B030DN bend relief for all EMG and event switch connections. The 0B LEMO connectors are 9.5mm in diameter and are identified with "LEMO FGG.0B" stamped by the red key mark. Note that the connections are numbered CCW with pin 1 to the left of the index key looking at the solder cup ends.

MA-300 Backpack (Harwin - 001 connector option)

Harwin connector

The first generation MA-300 backpacks use a 6-pin "Harwin" connector that is molded onto the cable during manufacture for all backpack signal connections. The cable and HARWIN connector form one unit and can not be seperated. Later MA-300 backpacks use a 4 pin connector - either BINDER or LEMO style.

MA-300 Backpack (Binder - 002 connector option)

BINDER connector

The MA-300 backpack uses either a 4-pin plastic Binder (pn 0997677004) or metal LEMO connector (below) for all analog signals. All Binder connections are numbered CW when viewed from the solder end. The event signals always use an 0B LEMO connector regardless of the analog connection option. The original MA-300 backback used a HARWIN connector (above).
