dimensions in mm (inches). tx20 series connectors 1.27mm (.050") contact spacing, emi shielded, pcb-to-pcb connectors the tx20 series is specifically designed to meet high density board-to-board interconnection requirements. tx20 series connectors enable either a horizontal or vertical connection between units without using a cable. this low profile half pitch 1.27mm (.050") connector is designed with an extremely low mounting height of 5.4mm (.212") for 10 to 120 contacts in horizontal connection. the connector features a rugged metal shell that interfaces with the unit, and the reliable ribbon style contact design protects against twisting. the metal ground lug provides excellent emi shielding for applications that require emi protection as well as high density. the flexibility of this connector makes it an ideal product for notebook computers and other high density applications such as disk drives and memory devices. ? ? ? ? ? ? ? ? ? ? ? ? ? ? general specifications number of contacts 10, 26, 40, 120, 200 (note 1) contact spacing 1.27mm (.050") current rating 0.5 amps dielectric withstanding voltage 500 vac r.m.s.
