The Zimmer and Peacock sensors can be attached to the board in plane or orthogonal, see image.  

For edge mounting to the board consider the following notes, ... 'there are no holes for the edge assembly as the connector has been flipped onto its side and its leads soldered onto rectangular (surface mount) pads, along the length of the leads. Since the leads are offset from the center of the adapter (as shown in the drawing ), it allows for it to rest against the PCB edge, providing additional mechanical support, the pads are  1.0 x 3.0 mm pads spaced with a 2.54 mm pitch'...
