New unsealed connector system suits automotive electronics applications
Published: 28 March 2013 - Rachael Morling
An unsealed connector system has been launched by Molex for direct connect or in-line mid-power body electronics applications in the automotive industry where space is limited – such as interior lighting, consoles, vanity mirrors, seats and door locks.
Using the field-proven Molex MX150 terminal design, the new unsealed connection system achieves significant space savings over traditional USCAR 1.50mm interfaces, claims the company.
The hinged Terminal Positioning Assurance (TPA) device, which is moulded as part of the housing, allows simple terminal insertion and secure terminal seating. The MX150 unsealed connector system’s enlarged push surface helps improve ergonomics, allowing for convenient, USCAR-25 compliant mating and unmating. Harness manufacturers can easily access the terminal latch directly, once the TPA hinge is opened, for quick reworking or field-repairs.
The MX150 unsealed receptacle and in-line connectors are available in 2-, 3- and 4- circuit versions as standard, though other circuit counts can be developed on request, with custom clip slots for increased design flexibility. To facilitate quick visual installation, 4 polarisation options are offered for each circuit size. The MX150 unsealed connector system offers high mating performance for mid-power (14 to 22 AWG) applications by using an integral locking latch. The reinforced front-beam terminal design provides a high contact normal force while minimising the insertion force.
