OEM Electrical Connector
The electrical connection to the Motus OEM PCB is through a Hirose DF40 series 20 pin
micro pitch board to board connector. These connectors have shock absorbing
features, a large self-alignment distance and high contact reliability. A positive click
should be felt when successful mating occurs between Motus OEM and the target
board. It should be noted that this connector is not designed for the Motus OEM to be
plugged in whilst power is applied to the user's PCB and connector mating cycles
should not exceed 50 cycles to ensure connector reliability.
The manufacturers part number for the required PCB connector is
Hirose Part #: DF40C(2.0)-20DS-0.4V(51)
The connector can be ordered from the following distributors using the following
numbers:
Digikey Part #: H11905CT-ND
Mouser Part #: 798-DF40C20DS0.4V51
Please see Illustration 58 below for the connector pin numbering.
