TE Connectivity


SL 156 Connectors Overview

TE Connectivity (TE) introduces its new generation of SL-156 wire-to-board crimp connectors with Terminal Position Assurance (TPA) device. The new housing design extends the existing SL-156 family and is fully compatible with SL-156 and MTA-156board headers. The new housing can therefore be used as a drop-in replacement with existing headers. There is no need to change the printed circuit board (PCB) of an application.

New design features of the SL-156 housings with TPA help the 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 250VAC 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 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 (AWG 18 to 24) to a PC board. The existing product generation is widely used across a wide variety of home appliances, garage door openers and other similar products. 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 housings, tin- or gold-plated terminals (contacts) and a secondary locking device. During installation, wire is crimped to a terminal and inserted into the housing cavity where it locks in place. The new housing design prevents accidental upside-down insertion of the terminal.

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 tangible click, confirming that the terminal is fully seated. The retainer will automatically push the terminal home if it is not inserted all the way. Once locked, the retainer also secures the contact from backing out under vibration. The TPA retainer comes in a 20-position strip that can be sized to fit any housing requirement.
