Harwin expands Kontrol range of industrial board-to-board interconnects

Harwin has expanded its Kontrol range of industrial board-to-board interconnects (BBi), adding single row connectors and cables to the 1.27mm pitch (0.05") connectors.

The range has been created to bridge the gap between high-end connectors and established pin header and socket solutions.

The launch adds to Harwin’s existing dual-row Kontrol connectors, extending the range with 49 new products – 21 SMT connectors and 28 double-ended cable assemblies – that include pin-count options of 2, 3, 4, 6, 8, 10 and 12.

All new SMT connectors in the series are available in vertical (male only) or horizontal (male and female) mounting options, with full shrouding and recessed contacts incorporated to prevent damage to the pins.

To improve assembly, the connectors have been polarised to prevent mis-mating, and also feature a tolerance to misalignment, with a permissible linear misalignment of up to 0.075mm and an allowable misalignment angle of 4.3o.

The latched design enables tool-free mating and un-mating, while surface mount tabs have been implemented to improve the retention force holding the connectors to the PCB. Location pegs have also been incorporated to assist with correct board placement and inhibit movement while soldering.

The Kontrol male and female double-ended cable assemblies include in-line connectors and UL-Specification 26 AWG ribbon cable, with an option of 150mm and 300mm options available.

Like the SMT connectors, full shrouding, latches and polarisation have been implemented to protect contacts and improve secure and blind mating.

The new single row products have the same electrical and reliability specifications as the existing Kontrol line-up, with a current rating of 1.2A per contact, and a 25mΩ contact resistance. The connectors are qualified up to 500 mating operations, operated across a 170C temperature range (-55 to +125C, board-to-board / -20-105C cable-to-board and cable-to-cable) and have been tested to withstand vibration forces of 20 G for up to 12 hours.

All connectors are available in tape and reel packaging for automated assembly processes, with disposable pick-and-place caps included where needed.
