Wedge Locks and Card Retainers
Conduction-Cooled Module Retention for VPX, CPCI, VME, ASAAC and ATR Chassis
Wedge locks clamp a plug-in module against the chassis cold wall. They do two jobs at once: they close the air gap on the conduction path, and they hold the module against shock and vibration. Fifty-seven catalogue part numbers: 3-segment, 5-segment, multi-slope, G/L handle and linked configurations, with the full dimension set published for every part number.

Every dimension below is taken from the 2025 product manual. Filter by configuration, then confirm the drawing before release to production. Rows marked On request have a drawing that we send with the quotation. A dash means the dimension does not apply to that variant, or is not published in the manual; ask us and we will confirm it on the drawing. Clamping force is given in newtons; 650 N is about 146 lbf.

Selection Guide
- Module length L60 mm to 248.9 mm, by part number. The lock has to match the rail: one longer than the rail cannot seat, one that is too short leaves part of the rail unclamped.
- Mounting holes and locking screw2, 3 or 4 holes in M2, M2.5 or M3; locking screw M3 or M4, internal hex to GB/T 70.1 (≈ ISO 4762 / DIN 912), so standard tools are enough.
- Reading the part numberIn XS-D130-5-2M2F1M3: XS is the wedge lock family, D the profile, 130 the module length in mm, 5 the number of segments, 2M2 two M2 mounting holes, M3 the locking screw thread.
