MQS Interconnection Systems
TE Connectivity’s (TE) Micro Quadlok System, MQS, interconnection system offers high packing density, robust construction and highest functional requirements. Despite its miniaturized design, it fulfills all requirements for a contact system suitable for use in automobiles and covers a wide range of application sectors in both waterproof and non-waterproof areas.
0.63
Proven & preferred 0.63mm connector system for European OEM's
4
Redundant contact point technology for higher reliability
.08mm
Different wire sizes ranging from 0.08mm² to 0.75mm²
MQS Contact System
The special feature of the MQS contact is the separation of the main functions – the internal contact body provides all electrical functions, while the superimposed steel cantilever spring provides all the mechanical functions by protecting and retaining the contact. A high primary terminal locking force, for such a small size system, is achieved by the use of a stainless steel metal locking lance. Secondary locking is provided by a pre-assembled plastic device from the MQS connector and its on the same level for all Quadlok terminals facilitating combinations within the housings.
The receptacle terminals have a square mating area and contact its four contact points (one on each side) on a 0.63 x 0.63 mm pin contact. MQS 0.63 terminals are offered in different wire size ranging from 0.08mm² to 0.75mm² and tin, silver and gold plating, reaching a max. current carrying capacity of 7.5 A at 80 °C. Having the right response on complex space constraints such as in battery cell modules the MQS flexible foil crimp terminals are the ideal solution. The Quadlock terminal portfolio is completed by Micro Power Quadlok (MPQ 2.8) to Power Quadlok (PQ 5.2) with higher current carrying capability up to 45 Amps.
Benefits

MQS Connectors
The MQS interconnection offers one of the most compact packages – by a centerline of 2.54mm x 2.54mm for non-waterproof and 4.00mm x 3.45mm for waterproof applications. Higher packaging requirements can only be fulfilled by Nano-MQS Portfolio. The MQS Connectors consists of wire-to-wire as well as wire-to-board versions, with several key codings and ensuring ergonomic assembly and safe installation.
The portfolio ranges from low (2-16 position) to medium and high (>40 positions) pin counts on the receptacle side. For lower pin counts the MQS Terminals are inserted safely into the contact cavity and latch with a clear click. For higher pin counts mating aids like levers are applied. Based on the plug uniform base centerline, the MQS interconnection ranges from MQS and Micro Power Quadlok (MPQ 2.8) to Power Quadlok (PQ 5.2) which can be subjected to higher current carrying capabilities. With the whole number multiplication of the centerline from 2.54mm for non-waterproof applications, the circuit board designer achieves a high level of freedom on designing the layout.
