Mill-Max Reveals the New Low Profile Target Connectors

Mill-Max has released its lowest profile target connectors yet with an above-board height of only 0.087 in. (2.21 mm). Target connectors are used in place of SMT pads on a PCB as the mating surface for spring-loaded pins. They provide expanded endurance and are useful in achieving specific distances between boards.

In order to enhance its existing 0.100 in. (2.54 mm) grid target connector lineup, the company introduced four new, low profile products. All of the connectors types are surface mount and available in single or double row packages and are offered with flat or concave target faces. Concave face targets provide additional surface area for mating and can aid in centering/alignment of components and/or boards fitted with spring-loaded connectors. Precision-machined pins with an overall length tolerance of ±0.0015 in. (±.00381 mm) aid to accomplish a connection of 0.005 in. (0.13 mm) or better for connectors up to 1 in. (25.4 mm) long. Progressive assembling techniques are used to ensure no burr projection on either the target face or the surface mount termination end.

Linking target connectors with spring-loaded connectors on opposing boards can be a simple and easy solution for making connections between stacked boards or docking stations and devices. These new connectors are ideally appropriate for low profile applications where multiple connections are required. The ideal choice to accomplish an ultra-low profile mated pair is by using these target connectors, the Mill-Max series 815 and 817 connectors single and double row correspondingly the 815/817 connectors, compressed to ½ stroke and used in combination with these new low profile target connectors, provide a board-to-board connector spacing of just 0.175 in. (4.45 mm).
