Right-angle PCB terminal type is available
D5 type: Pins at right angles to the right
D6 type: Pins at right angles to the left Drawings will be provided if requested
Looks like 5 is part of D5 and doesn’t refer to the operating force.
Good catch MKL. I’ve already sent off a request for drawings for the D5 and D6 terminal types to OMRON, hopefully with that information I can make some use out of the 53mm measurement.
