Gecko-SL Reverse Fix
1.25mm pitch Screw-Lok Connectors
Secure & Robust Miniature Connectors with additional fixing flexibility
The existing Gecko-SL range combines the miniature yet powerful 1.25mm
pitch connector system with the ease and strength of Screw-Lok (SL) jackscrew
fixings. These screw-loks are made from stainless steel to ensure a strong
and secure connection.
For additional design flexibility, a reverse fix screw-lok design has been added
to the range. The new screw-loks work in reverse to the existing design: the
screw-loks on the male connectors are the floating fixings, and screw into
the female connectors. The female connectors have an option for board or
panel-mounting, with a threaded stud on the rear of the screw-lok.
The Reverse Fix screw-lok design is available on male and female
cable housings, male and female Surface Mount, and male and female
Throughboard. The female connectors can be chosen as basic screw-loks,
or with the board-mount stud. Cable contacts and board mount nuts are
available for purchase separately.
Features and Benefits
Female connectors
ideal for board or
panel-mounting
In safety critical or “hot” unplugged connectors,
the fully and individually shrouded female can
now be the PCB mounted half, without having to
jack the connectors together from the underside
of the PCB.
