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 insulant used in the new Picoflex headers is fully compatible with the stringent demands of the glow-wire test prescribed by IEC60335 and is self-extinguishing in line with the requirements of UL94V-0.
The headers are therefore an ideal and cost-effective choice for use in a wide range of applications - including white goods, medical, and industrial equipment - where suitability for unattended operation is essential.
Fully compatible with standard connectors in the Picoflex range, the new headers can be supplied with tin or gold-plated contacts, and are available in versions with between 4 and 26 circuits.
Other options include printed circuit board pegs for positive location, and a choice of tube or tape-on-reel packaging.
When used in conjunction with Molex Picoflex discrete wire connectors, which incorporate finger tabs for easy tool-free mating, the new headers have a maximum mating force of 1.7N for tin-plated types, and 1.1N for gold-plated versions.
They are designed for applications requiring occasional mating and unmating and have a minimum durability of 30 cycles for tin and 100 cycles for gold.
The operating temperature range for Molex Picoflex headers is -40C to +105C.
Used with Picoflex discrete wire connectors, they have a maximum contact resistance of 15 milliohm, a di-electric withstand voltage of 750V AC and a minimum insulation resistance of 1,000Mohm.
