The H-LP Series Holders provide extra PCB retention and uniform elevation during processing and handling, making them ideal for high-shock and vibration environments. LEDs are aligned on equally spaced centers and rigidity is achieved via the unit's bifurcated locating pin, which holds the LED firmly in place. Narrow widths from 0.170 inches and rigid retention allow virtual side-by-side placement, saving valuable board space for station arrays. The holders accommodate any type of T-1 LED. The H-180C-LP series accommodates tri-lead T-1 LEDs for more sophisticated messaging applications.
