Rated at 500 mA per circuit and 125 VAC, this is strictly a signal connector; don't plan on pushing power through it.
The 0.80 mm pitch is the tightest constraint — it sets the pad spacing on the board and limits the trace routing between pads. The PPS insulation rated UL94 V-0 means the housing won't support combustion, a requirement for any equipment that goes inside an enclosure with a flammability standard.
The 3260-10S3(60) is a 10-position member of the Hirose 3200 series, which includes other position counts at the same 0.80 mm pitch. The key selection driver is the circuit count — match the 10 positions to your BOM line. The shielded variant with board guide is the distinguishing feature here; non-shielded siblings in the same series trade the EMI protection for a slightly lower profile.
