Slide-fit heatsink enclosures allow in situ adjustment of electronics

18 October 2007

A range of interlocking heatsink enclosures is now available from Astrosyn. The Lawtronics HSK extruded aluminium units consist of two sliding channels together with end panels. This arrangement enables the electronics to be worked on in situ when the top half of the casing is slid open.

The free-standing or 3U rack mount models provide a rugged, low thermal impedance housing for sensitive electronics. The standard units are large enough to house a toroidal transformer of up to 100VA.

Eurocard boards can slide into internal card guides, enabling power devices to be attached to the heatsink section of the vertical wall with an M3 screw and half nut, with no need for drilling.

Two boards can be mounted within the black anodised enclosure, and standard spacers can be used to support heavy components.

Available in 160mm or 220mm lengths, they have a normal wall thickness of 2mm, increasing to 7mm adjacent to power devices. Internal and external M4 nut 'T' slots are provided for mounting.
