LGH Connectors
LGH connectors are high-voltage lead connectors originally developed by Burndy, now carried under the TE Connectivity portfolio, and they remain a staple in designs where a single conductor has to carry several kilovolts safely through a bulkhead or into a sealed assembly. You will find them in CRT anode leads, radar and avionics equipment, X-ray and medical imaging gear, laser power supplies, and military test sets. The family splits into a few practical groups: receptacles that mount to a panel or housing, plug assemblies molded onto high-voltage silicone or Teflon leads, and mating kits sold with the lead already terminated. Voltage ratings commonly run from 5 kVDC up to 20 kVDC and beyond depending on the series, with polarized and non-polarized versions to control mating. What buyers actually check before placing an order is fairly consistent: the exact TE or legacy Burndy part number, the lead wire gauge and length, whether the assembly is molded or field-attachable, and the voltage and altitude rating, since corona performance drops at altitude. Here is the honest trade-off with this category. Many LGH part numbers are mature or discontinued at the factory, so authorized channel stock is thin and the open market fills the gap. That means lower prices sometimes come with date-code risk or repackaged parts of unknown origin, while traceable stock costs more but ships faster. Our advice is to treat any molded-lead LGH assembly without paperwork as suspect, because the overmold hides the termination quality and failures show up at operating voltage, not at incoming inspection. If you know the part number, check current stock and request a quote at icxing.com. If you only have the legacy Burndy number or a drawing, send it over and we will cross it.
Frequently Asked Questions
The LGH connector I need shows as obsolete at TE. Is stock from an independent distributor safe to buy?
It can be, but you need traceability. Ask for photos of the packaging, date codes, and any certs of conformance before paying, since molded high-voltage assemblies are frequently remarked or repackaged. We pull from vetted sources and disclose what documentation exists, so you know exactly what you are buying.
How do I make sure I order the right mating half for an LGH high-voltage connector?
Match the full part number, including polarity, because LGH receptacles and plugs come in polarized and non-polarized versions that do not interchange. If you only have the old Burndy number or the marking on the housing, send it to us and we will cross-reference it to the current TE equivalent.
What is a realistic lead time for LGH connector assemblies with molded leads?
Factory-built molded-lead assemblies often run 12 to 20 weeks when they are made to order, which is why most buyers look for existing stock first. In-stock units from our warehouse or partner stock typically ship within a few days, but confirm the lead length and wire gauge match your drawing before ordering.
