Dual-thread PCB retainer

12 May 2010 Enclosures, Racks, Cabinets & Panel Products

The new Series 236 Card-Lok from Calmark incorporates a dual-thread design that allows the device to be compressed from both ends by turning a single screw, which means that it can be tightened or released more quickly than conventional PCB retainers, thereby helping to reduce 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 (2 mm or 2,5 mm).

Manufactured by Calmark, one of Schroff’s sister companies within the Pentair Technical Products Group, the new Card-Lok features a lightweight five-segment aluminium construction using solid-frame extrusion for 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 329,9 mm, and the device measures 5,84 mm high, with a width expandable from 7,32 to 8,64 mm. Primarily designed for use in systems that are subjected to high levels of vibration, series 236 is suitable for securing PCBs in demanding environments such as avionics, defence, transportation, and the oil and gas industries.
