Original Press Release:
New SL-156 Wire-To-Board Connector - Friction lock and TPA Device Help Workers Achieve Consistent Interconnection Quality - Additional Levels of Safety
New SL-156 wire-to-board connector - Friction lock and TPA device help workers achieve consistent interconnection quality - Additional levels of safety HARRISBURG, Pa. - TE Connectivity (TE), formerly Tyco Electronics, has unveiled its new generation of the SL-156 wire-to-board crimp connector with a Terminal Position Assurance (TPA) device. The connector's new housing design extends the existing SL-156 family and is fully compatible with SL-156 and MTA-156 board headers. This new housing can be used as a drop-in replacement with existing headers - removing the need to change the printed circuit board (PCB) of an application. New design features of the SL-156 housings with TPA help shop floor workers to achieve a constant level of interconnection quality. The single-row connectors with a .156 (3.96 mm) contact pitch are available with 2 to 12 positions and are rated for up to 250 VAC and up to 10 Amps. Breakaway-style retainers add the TPA function to secure the contacts in the housing cavity against backing out. Polarization tabs make sure that the housing and header are mated correctly. Efficient and Economic Interconnection System The SL-156 connector with TPA is designed to interconnect 2 to 12 discrete power lines (sizes 24 to 18 AWG) to a PCB. The existing product generation is widely used across a large number of home and household appliances, garage door openers and many more. The new SL-156 connector with TPA builds on the experience from this universal use and adds further benefits. Integrated TPA Confirms that the Contacts are Fully Seated SL-156 connectors with TPA are modular products that consist of housing, tin- or gold-plated terminals (contacts) and a secondary locking device. During an installation sequence, wire is crimped to a terminal and the terminated wire is inserted into the housing cavity where it locks in place. The new housing design prevents the worker from accidentally inserting the terminal upside down because the cavity can only be loaded in one way. Once the terminal is in place, the TPA retainer is pushed into the cavity and onto the housing. The TPA retainer's locking slot slides over a locking tab on the outside of the housing and engages with a click. When the retainer snaps in place, it confirms that the terminal is fully inserted as the retainer part inside the cavity will automatically push the terminal home if it is not inserted all the way. Even under adverse shop floor conditions, the tangible click of this device signals that the terminal is in place. Once locked, the retainer also secures the contact against backing out under vibration. The TPA retainer comes in a 20-position strip that can be sized to fit any housing requirements. Contact Lubrication As another level of added safety, the SL-156 terminals come with lubricated contacts. This helps to counter the possible formation of whiskers on tin-plated contact surfaces that are, for example, caused by mechanical stress and fretting corrosion. As whiskers can cause short circuits, arcing and other potential electric problems, contact lubrication is an added benefit for applications that have operating conditions known to make whisker formation more likely. The new SL-156 connector with TPA is CSA approved and UL recognized. The housings are manufactured from UL 94-0 rated nylon and the connector can be used at operating temperatures between -55 °C and 105 °C.
