Thermal Clamps Amphenol Series SIHD GT zzzzzzzzzzzzzzzzz
. • MAXIMUM RESISTANCE TO SHOCK AND VIBRATION : Very low wear and resistant to extreme shock and vibration, even when used in harsh environments • NO MOVING PARTS : The precision assembly permits the three components (body, spring and rod/cam) of the thermal clamp to stay together, even when in th unlocked position. a • SENSITIVE AND VISUAL INDICATION : The top end of the rod/cam provides visual indication that shows the “open” or “closed” position for ease of inspection. MAXIMUM RELIABILITY • QUICK LOCKING AND UNLOCKING : Unlike others on the market, Series SIH GT thermal clamps feature a quick, quarter-turn locking mechanism that provides a positive and fast assembly. - • ZERO INSERTION AND EXTRACTION FORCES : The insertion and guiding process of the PCB in its location requires no additional force. • Board lengths between 80 mm ( 3.15 in ) and 240 mm ( 9.45 in ) can be accommodated once the cold wall and heat sink are specified - in increment of 20 mm ( 0.787 in ). • Series SIHD-GT thermal clamps are compatible with different heat sinks thicknesses. • MAINTAINABILITY : the unique design makes field repairs quick and easy. Repairs can be accomplished without use of any special tool. Although the SIHD GT thermal clamps have been tested for over one thousand lock-unlock cycles, they have been derated and specified for 500 fully loaded cycles. This, in most cases, will exceed the overall system life, virtually eliminating service and maintenance. • Various mounting options are available. • Other custom styles are available upon request. MAXIMUM THERMAL TRANSFER • UNIFORM HEAT TRANSFER : Its unique design produces a uniform pressure distribution along the PCB edge for absolute best heat transfer, which avoids damaging the heat sink and provides a better thermal conduction. • The uniform clamping pressure eliminates hot spots along the PCB interface producing an even distribution of heat along the entire edge. • Thermal couple between the cold wall and the heat sink is created by a direct metal to metal contact providing more heat transfer capability than conventional wedge style retainers due to the constant pressure and the flexibility of the spring

• Avionic systems • Submarine equipment • Ground military vehicles • Superior retainer for high density electronic devices running in very high vibration environments. • Designed to comply with MIL- STD-810E. Amphenol offers a new advanced design. Series SIHD-GT thermal clamps are designed to ensure the thermal coupling (heat dissipation) between the heat sink of a printed circuit board and the cold wall of a box (for Daughter Board), or of a backplane (for the Mother Board). At the same time they ensure the guiding of the boards in its locations, as well as the locking of the Daughter Boards into the right position relative to the Mother Board by a 1/4 turn. Ease of use, safety in vibration, low weight and space saving are benefits of this design. Series SIHD-GT thermal clamps are available in the following designs : - a left type and a right type, - different platings, - variety of lengths, - different locking devices (standard and custom tools).
