The layout's rows run along +X, and its next row is towards +Y. The pins go down through the board.

	72	+The sheets name no materials and give no weight.
	73	+
	74	+**Proportions.** The sheets dimension the rows and the case width but not the gap between them: the rows are centred across the case. The 36.11's coil and contact pins are taken as 0.5 thick across the case, as drawn (the sheet gives only their width along it). The small standoffs under the 32.21 (0.4) and 34.51 (0.3) cases aren't modelled: the case stands on the board. The flat pack's pins bend 1.3 above the board, the standing version's 1.3 from the case side. The inside is the Omron proportions: a 0.5 cover and base, and a copper block filling 0.27 of the inside.
	75	+
	76	+Mass (no weight in the sheets to compare with): 30.22 4.75 g, 32.21 4.69 g, 34.51 4.39 g, 36.11 9.8 g, 40 series 20.2 to 20.3 g.
