25 thanks to the hinged connection of the connector, the boards can be rotated 90? so that they can be moved from parallel to vertical positions even when electricity is turned on. thus circuit checks and adjustment of the equipment is possible even in tight spaces. header leads are staggered for vibration resistance and for easy board design. features ? low profile, matable even after mounting on the pc boards compact and low profile with 2.0mm (.078") pitch and 6.0mm (.236") height after mounting on the pc board. connector halves can be mated even after they are mounted on pc boards and the pc boards are installed in the equipment. thus connection between boards is easy. ? highly reliable connection due to the secure locking mechanism and fork-shaped contact mating sections, highly reliable connection is assured even under severe conditions such as vibration or shock. specifications ?current rating: 1.0a ac, dc ?voltage rating: 100v ac, dc ?temperature range: - 25?c to +85?c (including temperature rise in applying electrical current) ?contact resistance: initial value/20m max. after environmental testing/40m max. ?insulation resistance: 1,000m min. ?withstanding voltage: 800v ac/minute ?applicable pc board thickness: 1.6mm(.063") * contact jst for details. standards recognized file no. e60389 certified file no. lr20812 hqs connector hinge type board - to - board connectors 2.0mm (.079") pitch
