MUNICH, Germany - Erni Electronics has expanded its 0.8mm MicroStac SMT connector series to include a 10- (single row) and 54-pin (dual row) version. The MicroStac advantage is based on a patented hermaphroditic design, a special design requiring only one part number which enables reduced logistic and inventory costs for board-to-board applications. The powerful combination of the MicroStac's miniature construction and its innovative design makes it suited for extremely compact and demanding applications. Furthermore, the scope of applications is very broad, ranging from sensor technology, medical instruments and mobile communication to automotive electronics, automation engineering, measurement technology, test equipment and building automation. For medical applications, new antistatic versions are now available upon request.
Antistatic connector versions are suited for medical applications
The SMT construction and design of the MicroStac allow for economical and automatic assembly. The stability of the miniature connector is facilitated through a tilt-proof contact principle with dual side positioning of the contact on the PCB. In addition, with its corresponding features of minimal weight (just 0.18g for the 6-pin design), 100% SMT co-planarity of < 0.1mm="" and="" suction="" areas="" integrated="" in="" the="" insulating="" body="" for="" pick-and-place="" assembly,="" the="" connector="" series="" is="" suited="" for="" high-speed="" manufacturing="" requirements.="">
In spite of their very compact construction, the products can achieve a high current-carrying capacity. The contact is formed through precision stamping, a process which offers the most reliable form of contact possible. As a result, the contacts offer an extensive cross-section for low ohmic resistance, while at the same time providing a large radiating surface that yields higher power carrying capabilities than similar products. With an ambient temperature of 20°C and current feed to all contacts, the 50-pin connector can transfer 1.6A per contact (in acc. with IEC 60512, test 5b). In summary, the 50-pin connector can safely and reliably carry 80A inside a very small footprint.
Within the connector family, new versions are now available with 6, 9, 10, 12, and 14 pins (all single-row), and 50 and 54 pins (both two-row). Depending on the connector version, the board-to-board height ranges from 3.0 mm to between 5 mm and 6.5 mm. Despite the sub-miniature design, the connector is designed to be used in multiple mated pairs between two boards. Subsequently, when using the connector, there is no need to fear 'negative tolerance stack up'. The permissible center offset, when connected, is +/- 0.7 mm in the longitudinal direction and +/-0.5 mm in the transversal direction. The permissible angular offset is +/-4 degrees.
MicroStac connectors feature a high temperature-resistant insulating body (PA46), and 100% SMT coplanarity to ensure a secure soldering experience. The black isolating body allows simple visual recognition during automatic assembly and, when delivered in the antistatic packaging, the connectors are protected and ready for automatic assembly.
