With an internal machine board-to-board connector, circuit boards can be connected horizontally, parallel, or perpendicularly by joining the receptacle (TX24) and plug (TX25).[Features]· A receptacle and plug along with a straight through-hole type and right angle thorough-hole type are available.· Ribbon-type (flat) contacts are used with a long contact stroke, excellent contact reliability/stability, and resistance to prying once mated.· The straight through-hole type offers 3 insulator heights and a parallel circuit board gap of 12 to 24 mm (2-m gap).・Both receptacle (TX24) mating sides have an insulator mating guide, which excels at strong insertion, and is perfect for lock & panel mountings.・This type has a satisfying ‘click' action when inserting and extracting.・Hook pin and hook-less types are available to temporarily hold the circuit board while soldering and also prevent the solder from oozing.・The contact terminal allows for simple circuit board pattern design with a 1.27-mm pitch and 1.905-mm array gap with a 4-row staggered arrangement.
