Laird offers the USB (Universal Serial Bus) Type B connector gasket.

The unique design easily snaps onto the connector prior to placement on the

printed circuit board and fits all Series B USB right angle connector brands.

Made from high performance beryllium copper, these gaskets provide superio

grounding characteristics and enhances the shielding of the connector due to

the short electrical path to the ground plane provided when the gasket makes

contact with the connector.

• Gasket easily snaps onto the connector for a secure fit

• Connector/gasket assembly can be placed onto the board via pick-and-place

• High clip force attaches clip to connector body for good electrical contact

and secure transport prior to soldering

• Once the shielded connector assembly is soldered to the PCB, the shield is

captivated between board and connector and provides reliable contact

between the connector and faceplate

• Simple compact design fits within 0.625 in. X 0.625 in. (15.875 mm X

15.875 mm) windows

• Available in a variety of plated finishes

“D” CONNECTOR SHIELDING

Laird offers the “D” Connector Shield Series for grounding and shielding of

D Subminiature Connectors. This series is designed to fit most commonly

used 9 pin through 68 pin connectors.

• Available in stainless steel and beryllium copper, conductive elastomers,

oriented wire and other materials

• Improved 20 degree angle flange design on metal connectors:

- provides continuous contact for increased shielding effectiveness

- fills gaps and adjusts for irregularities in the flatness of the

mounting surface

• Beryllium copper parts available in UltraSoft

low force version and

available in a wide variety of finishes, see page 17

• Custom shapes and designs also available

• Versatile front or rear mounting

SLOTTED “D” CONNECTOR SHIELDING

The slotted D connector gaskets provide shielding for most 9 through 50 pin

connectors. The separate finger design provides maximum surface contact,

provides high shielding effectiveness and low compression forces.

Slotted D connector gaskets are available from stock in copper beryllium and

stainless steel. Copper beryllium parts can be plated to a variety of finishes

for galvanic compatibility, see page 17.

“D” CONNECTOR SHIELDING/SLOTTED “D”

All dimensions shown are in inches (millimeters) unless otherwise specified.

Laird provides fiber optic shielding, which provides excellent EMI shielding

around the faceplate aperture which houses board mounted fiber optic

transceivers. This EMI shield easily fits over the industry standard 1 x 9 style

fiber optic transceiver with a duplex SC connector. The shielded transceiver

is then inserted into the faceplate.

• Fits all 1 x 9 style fiber optic transceivers with duplex SC connectors

• Provides shielding around the faceplate aperture which houses board-

mounted fiber optic transceivers

• Fits most Tyco (AMP) and Methode guide rails common to routers, switches

and other network hardware

• Requires no extra mounting holes or solder

• Provided in stainless steel for high galvanic compatibility

• Simple snap-on assembly

HOW TO ORDER:

To obtain the two piece assembly, order part number 95-702.

Laird offers the GBIC Shield for reducing emissions from GBIC

(GigaBit Interface Converter) fiber optic transceivers. Fiber optic transceivers

can be a troublesome source of EMI because they emit high-frequency signals

and are located adjacent to large apertures in the enclosure. The GBIC Fiber

Optic Shield assembly reduces the radiated emissions from the transceivers

by conducting interference current away from the transceiver and onto the

enclosure surface.

Simple assembly of the shield is accomplished by snapping the two shield

halves onto an uninstalled guide rail assembly. The rail is then mounted onto

the printed circuit board in the normal fashion.

Spring finger design on both halves of the GBIC shield provide grounding for

both sides of a transceiver module. In addition, the bottom half fingers can

provide a low impedance connection to the circuit board ground plane.
