What This Guide Module Does in the AdvancedTCA Chassis
The TE Connectivity 1-1469267-1 is a guide module accessory for the AdvancedTCA series backplane and card-cage systems. It is a Type A1 variant with a vertical short pin, designed to align and key plug-in boards during insertion into the chassis slot. The guide module prevents misalignment of the backplane connectors and reduces shear stress on the mating interface during board seating. This part is specified as Type A1, which defines the pin length and keying profile for the corresponding slot on the backplane guide rail. The vertical orientation and short pin length suit standard board depths in an AdvancedTCA shelf.
