Mill-Max addresses the connector needs of the growing field of LED lighting applications with products such as receptacles and sockets suitable for LED Bi-pin bulbs and interconnects ideal for co-planar mating of LED driver boards. The range covers a variety of through-hole and surface mount products suitable for LED lighting requirements.
For applications such as strip lights requiring end-to-end mating (daisy chaining) of boards, co-planar board mating connectors of the surface mounting HSMT family are available on 100 mil and 50 mil grids. These headers and sockets have Z-bend style lead terminations providing a low profile and easy inspection of solder joints.
A recent addition is the 339-10-1XX-40-000000 series surface-mount header/jumper. This has Z-bend SMT terminations on both ends, useful for creating a soldered, daisy chain connection of two co-planar boards. This can be convenient when there is only access to the top of the board and/or a permanent connection is desired. The low profile of all these connectors (100 mil maximum) makes them especially appealing for use in LED strip lighting systems.
These connectors are supplied in standard plating options of gold or tin with high-temperature insulators suitable for RoHS compliant environments and for reflow soldering. The co-planarity of the connector leads is 5 mil for connectors up to 1 inch in length. Rounding out the HSMT connector line are spring-loaded products in single-row strips and individual components.
The through-hole products offered for co-planar board-to-board interconnects include connectors on 50 mil, 70 mil, 2 mm and 100 mil grids. These are right angle connectors and like the SMT products, they are ideal for daisy chaining of boards, are low-profile and have high-temperature insulators suitable for reflow soldering processes. Plating options are gold and tin (RoHS compliant) as well as tin/lead.
Lastly, to bring power to the driver board, Mill-Max has connectors with solder cup terminations. These include 100 mil grid connectors and can handle wire sizes up to #20 AWG.
Receptacles and sockets
Mill-Max also manufactures a selection of off-the-shelf receptacles that accept LED bulb leads conforming to the MR11 (G4 Style) and MR16 (G5.3 Style) base configurations. It offers through-hole solder-mount, press-fit, open bottom, SMT and wire termination options to suit the application.
These receptacles can be mounted in housings to make connector assemblies or fixed directly to a circuit board. The company can quickly manufacture the two-pin socket of a customer’s choice by utilising Fr-4 epoxy for the housing and standard receptacles with the termination style required. For those applications where high operating temperatures are a concern, the standard beryllium copper contact can be replaced with a beryllium nickel contact suited for higher temperatures (above 150°C).
All Mill-Max pin headers, receptacle sockets and spring pin connectors feature high-speed screw machined pins, receptacles and spring pin components manufactured to precision tolerances. Inside each receptacle is a precision stamped beryllium copper contact. Spring pins contain durable, gold-plated beryllium copper or stainless steel springs.
