Kensington Electronics Inc. stocks CONEC’s compact M12x1 PCB socket connectors, which enable easy in-field assembly and provide secure data transmission and high current transmission in space-constrained, harsh-environment industrial applications including automation and drive technology, industrial interfaces, assembly and production equipment, process control and automation equipment, manufacturing equipment, and servo motors. The compact, two-part connectors are comprised of an insulating body and shielded socket housing with integrated O-rings that protect against dust and moisture ingress even when unmated and provide robust IP67 protection when mated. They also feature screw connections that maintain connectivity in even high-vibration applications and are available with A-, D-, and L-coding. Additional options include 4–12 positions and front and back panel-mount configurations suitable for housing wall thicknesses of 2–3mm and PCB thicknesses of 1.6mm. D-coded variants are especially ideal for high-data-rate transmissions and L-coded variants can handle high current loads up to 16A while requiring 30% less installation space than 7/8 overmolded connectors. The series also supports combined mounting, offers maximum design flexibility in devices where the M12x1 socket thread is directly formed, and have contacts designed to be snapped into circuit boards and then selectively or wave soldered. Additional benefits include large tolerance compensation between board and socket, various socket geometries, low PCB load forces, low contact resistance, and RoHS compliance.
TE Connectivity’s Economy Power (EP) 2.5 wire-to-board and wire-to-wire signal connector family is based on a 2.5mm pitch, rated for 250VAC at up to an industry-leading 4.2A, and comprised of standard loose headers, standard headers on tape in ammo box packaging, low-insertion-force socket contacts, and dual-row connectors with terminal position assurance (TPA) mechanisms. Designed to deliver convenient, reliable connections in the signal and low-power circuits of space-constrained electronics applications that incorporate a variety of sensors, including household appliances, commercial and building equipment, industrial machinery and equipment, generators, HVAC and vending controls, coin changers and vending machines, lighting systems, and garage door openers, the family offers up to 40 positions, supports 26–20AWG wire and operating temperatures extending from -55°C to +105°C, and provides two levels of mechanical and electrical reliability: a positive locking latch that provides audible confirmation of engagement and prevents the plug housings and post headers from vibrating apart and optional TPA devices that help ensure proper terminal seating. The family is available with standard- and low-insertion-force contacts for 26–22 and 24–20AWG wire and each contact features a serrated wire barrel to aid in wire retention, an insulation barrel, a locking window, and anti-fretting contact lubricant. Additional features include multiple color selections for easy identification and mating, polarization tabs to help prevent post misalignment, and asymmetrical terminals that can only be loaded one way within the housings. The family is also available with selectively loaded headers upon request and is intermateable with similar competitive products for retrofit applications. EP 2.5 headers shipped loose or on tape in ammo boxes are available in vertical, single-row configurations with 2–8 positions and in various colors; low-insertion-force socket contacts for EP 2.5 connectors require a maximum insertion force of 3.5N as opposed to the 8.9N maximum insertion force required for the standard contacts; and EP 2.5 dual-row connectors employ V-0-rated, glow-wire-compliant materials and TPA devices.

Materion’s Alloy 390 and Alloy 390E enable design flexibility ideal for the development of small-form-factor power and signal interconnects employed in harsh environments, including burn-in and test sockets, production sockets, power connectors, card-edge connectors, handheld and portable electronics, automotive power applications, switches, relays, sensors, and controls. Alloy 390 copper beryllium alloy (UNS C17460) offers the high strength of Alloy 25 (C17200) combined with the electrical conductivity of Alloy 3 or Alloy 174 (C17410 or C17510), while Alloy 390E provides the same, but with greater formability. Both materials exhibit high conductivity, which helps maintain the flow of electrical and thermal energy, reduce device operating temperatures, and improve device battery life; exceptional stress relaxation characteristics, which helps retain contact force at elevated temperatures to ensure high-reliability performance; robust resilience, which enables large displacement tolerances and prevents permanent deformation; and excellent fatigue strength, which reliably prevents contact force degradation over even long lifecycles.
