Knowles Precision Devices
Metal Frame J-Lead Termina Knowles Precision Devices ' leaded standoff components are high-reliability parts capable of 3,000 thermal cycles with no degradation of interconnects when mounted on an FR4 board. Compared to a surface-mounted chip, lead flexibility accommodates much more board bending and flexing before internal cracks form. Leaded standoffs are advantageous because they position ceramic elements off the board, ultimately providing more design flexibility. With high voltage ratings, standoffs can help control...

The 9 essential rules for safe shackle use . NOTE: The angle of loading affects stress in the shackle. As the horizontal angle decreases, stress increases -- and the effective WLL of the shackle is reduced. Rule 3: Choose the Correct Type of Shackle. There are multiple shackle styles, each designed for specific uses: Anchor (Bow) Shackles - For multi-leg slings or side loads. Chain (D-Shaped) Shackles - For straight-line loads only. Screw Pin Shackles - Quick to install and remove. Bolt-Type Shackles - For permanent, long-term... (read more)Browse Shackles Datasheets for Columbus McKinnon Corporation -
