An accelerometer (50, 100, 120, 130) includes a substrate (58) and a proof mass (54) spaced apart from a surface (56) of the substrate (58). Compliant members (62) are coupled to the proof mass (54) and enable the proof mass (54) to move parallel to the surface (56) of the substrate (58) in a sense direction (68). Proof mass anchors (60) interconnect the compliant members (62) with the surface (56). The accelerometer (50, 100, 120, 130) includes an over-travel stop structure (52, 102, 122, 132) having stop anchors (70, 72) coupled to the substrate (58). The stop anchors (70, 72) are coupled to the substrate (58) at positions (76) on the surface (56) residing at least partially within an anchor attach area (71) bounded in the sense direction (68) by locations (78) of the proof mass anchors (60) on the surface (56).
