Dual-thread PCB retainer design cuts installation time

The actuating screw head is recessed to save space and can be specified as slotted or with a choice of metric hex sockets (2mm or 2.5mm).

Manufactured by Calmark, one of Schroff’s sister companies within the Pentair Technical Products Group, the new Card-Lok features a light-weight 5-segment aluminium construction using solid-frame extrusion for maximum rigidity and resistance to distortion under load. Enclosed stainless-steel retaining springs are used to maintain alignment of the segments during insertion.

The PCB retainer is available with various finishes, including black anodised, electroless nickel and clear film. Standard lengths range from 121.9 to 329.9mm, and the device measures 5.84mm high, with a width expandable from 7.32 to 8.64mm.

Primarily designed for use in systems that are subjected to high levels of vibration, the Series 236 Card-Lok is ideal for securing PCBs in demanding environments such as avionics, defence, transportation, and the oil and gas industries.
