Brand: Parts Express. MPN: 073-0102. This LED lighting strip splice makes connecting LED lighting strip segments together easy. Originally designed for use with indoor RGB LED strip lighting (without the IP65 resin drip coating) for a solder-free connection, this splice can be used with flexible IP65-rated LED strip lighting with the use of solder. A clam-shell cover provides protection against accidental shorting. Dimensions: 15 mm W x 16 mm L x 5 mm H. Sold in bags of 10.
Instructions for use with coated, IP65-rated RGB LED strips:
1) Remove about 1/4" of the resin drip coating from the end that is to be inserted into the splice, exposing the four solder pads
2) Place a very small amount of solder on each pad (just enough to color the pad silver, 0.031" thickness solder is recommended)
3) Insert the exposed portion of the strip into the splice, two retaining clips holds the strip in place
4) Heat tabs directly over the solder pads while pressing down
5) Close clamshell cover, repeat steps with opposite side, cover and seal with heat shrink (18 mm heat shrink with adhesive is recommended)
Note: When directly connecting multiple LED strips together using this 4-pin male-to-male connector, it is important not to exceed a total series length of 33 feet. Doing so can damage some controllers, power supplies, and cause resistors within the LED lighting strip to overheat, creating a color difference between strips.
