Low Profile 2 mm Pitch Spring-Loaded Connectors

Low Profile, 2 mm Pitch Spring-Loaded Connectors

Space saving single and double row SMT connectors with .197” (5 mm) initial height

Mill-Max announces the introduction of low-profile, surface mount additions to its 2 mm pitch spring-loaded connector range. These connectors feature a reduced PCB footprint and compact interconnect height, making them well suited for dense electronic packaging requirements.

Reducing size and using space efficiently is paramount for designers in the ever-shrinking world of electronic devices. With the introduction of these new connectors, Mill-Max has added a low-profile option to its 2 mm pitch spring-loaded product line to help achieve these goals. The single and double row connectors have surface mount terminations with an above-board height of just .197” (5 mm), 33% lower than the current product offering, while maintaining a full stroke capability of .055” (1.4 mm).

Addressing Critical Market Needs

The demand for small scale electronics cuts across industries and markets including medical, robotics, industrial, military, commercial and consumer products. One of the fastest growing markets is wearables and two industries in which they are widely used are medical and military. In the medical field they are commonly used for monitoring and collecting vital data such as heart rate, glucose, and blood pressure while the military employs them for soldier worn gear supporting lighting, sighting devices and communications. Wearables require robust electrical circuitry and connections in a minimal amount of space; these new spring-loaded connectors deliver just that for making board-to-board connections; power and data connections between devices, docking stations and diagnostic equipment; as well as facilitating quick connections between components while providing high cycle life. These types of connectors are also commonly found in industrial sensors, controllers, data loggers, surgical and diagnostic tools, and a wide array of consumer products.

Product Specifications

The connectors are available in single row, 836-22-0XX-30-002101, and double row, 838-22-0XX-30-002101, configurations. Single row are offered in 2 – 10 positions while double row come in 4 – 20 positions. Packaging options are bulk (tube) or tape & reel. The part numbers to specify tape & reel packaging are 836-22-0XX-30-002191 (Single row) and 838-22-0XX-30-002191 (Double row).
