ELECTRONICS: ITT Interconnect Solutions‘ line of breakaway connectors — the Nemesis Series and MKJ Series — incorporate a simple push/pull mating mechanism to engage and disengage the connector systems. The coupling mechanism utilizes a canted spring design, which allows for a quick disconnect and ratings of more than 5,000 cycles.
Theey also feature ITT’s spring probe pin/pad contact system. The contact design utilizes an internal clip mechanism that stays in constant contact with the contact itself, helping to reduce electrical contact resistance. Additionally, the spring probe contact system accommodates misalignment issues, making the contact system much more forgiving.
The spring probe system allows the connector receptacle to house individual touch pad contact areas, providing a highly effective electrical engagement point of contact. Further, the spring probe contact system and touch pads allow for ease of cleanability in the field, where dirt, moisture, mud, sand and other contaminants may be present. The individual touch pad contacts contain no crevices for contaminants to accumulate.
The Nemesis Series sealed, lightweight, miniature connectors are resistant to salt spray for more than 500 hours, measure less than 15 mm in diameter and have an anti-reflecting coat. Maximum current rating for the Nemesis WT connectors is 3A and voltage rating is 200V ac RMS at sea level. Minimum insulation resistance is 5,000MΩ and maximum contact resistance is 8mΩ. Operating temperature ranges from -40 to 100C. Life span is to 2,500 cycles.
The MKJ Series miniature, circular connectors are available with a variety of mounting options for both crimp and PC board contacts, including in-line, jam nut, front mount, square flange mount and flange mount. The connectors are up to 71 percent lighter and 52 percent smaller than comparable devices, and feature size 23 pin-and-socket contacts that have the equivalent electrical performance of size 22 contacts. Dielectric withstanding voltage at sea level is 500V ac RMS, 60Hz. Operating temperature ranges from -55 to 150C.
Typical pricing for the Nemesis breakaway connectors is approximately $90 per mated pair for 1,000 sets. The breakaway connectors will be available in Q2 2010.
