Save space with shrinking USB connectors
The new series of mini-BTM USB connectors from Molex take up only about 1/8th of the space of standard USB-B connectors.
Power connectors meet SSI specifications
The new DPS/MPS power connectors from Molex meet the Server System Infrastructure (SSI) open specifications for backplanes.
The 1.80mm standoff version even allows a 1.5mm high ASIC chip to be mounted beneath the connector.
Both versions of SDIO card connectors accept industry standard SD memory cards in applications such as PDAs, digital video cameras, digital still cameras, notebook computers, electronic dictionaries, home video game machines, cellular phones, and other small form factor electronic devices.
The connectors are designed to withstand high durability card insertions and extractions of up to 10,000 times; and provide good resistance to shock and vibration while ensuring high electrical contact integrity when used.
The plastic cover of the connector is made of heat-resistant polymer and provides good protection of electrical contacts as well as added card stability.
One distinct feature of the 67781 series is the connector's unique stainless steel card lock pin which gives good mechanical support during card insertion, while offering high chemical and moisture corrosion resistance.
The connectors provide card insertion detection and read-write switch functions via the "protect" pin extension which makes contact with the "protect-and-detect" pin.
The "protect-and-detect" terminals of the connector provide card security and read-write capabilities.
Bevelled spring contacts within the connector housing secure connector-to-card mating.
These 9-circuit connectors are rated at 0.5A and 250V DC per contact and feature terminal and pin coplanarity of up to 0.1mm.
They can be ordered in embossed tape packaging for automatic board mounting.
