Harwin Adds Horizontal Male Connectors To Its Gecko-SL Series

  • Right angle termination to 1.25mm pitch connectors
  • Enabling substantial space savings for cable-to-board applications

The popularity of the Gecko range of connectors by Harwin amongst engineers, as a lightweight alternative to conventional Micro-D connectors, has prompted the company to extend this range by including horizontal male connectors.

Male through board connector at 90 degrees to the PCB offers layout flexibility to maximise the space above the board. Connectors can now be located at the PCB edge by routing a mated cable sideways outside the PCB stack.

A key benefit from this connection style is CubeSats, where many designs involve a series of PCBs in a dense stack, with all cabling routed into the space outside the stack. Similar tight space restrictions occur in avionics (particularly UAV design), large satellites, military (such as radar and portable communication equipment), robotics and motorsport.

Easy to use


Harwin’s horizontal format Gecko-SL connectors are fitted with stainless steel screw-loks, designed to be Mate-Before-Lock for ease of use. It requires just a simple push for the connectors fully join together before engaging in the screws. The standard screw-lok with board-mount (with the engaging screw on the female connector) or the reverse-fix (with the engaging screw on the male connector) can be chosen. Pin counts range from 6 to 50 contacts.

The horizontal connectors can also be used with female PCB connectors to give a motherboard/daughterboard arrangement, which can be useful for replacing modular PCBs or large equipment systems.

These highly-reliable, new horizontal components deliver industry-leading robustness with an operating temperature range from -65 degrees Celsius to +150 degrees Celsius. The connectors possess strong vibration (20G at 2kHz for 6 hours) and shock (up to 100G) resilience, and show very low outgassing, satisfying both NASA and ESA specifications. Current rating is set at 2.8A max single contact; 2A per contact if all are loaded.
