Adjustable Hold-Down Gates

Adjustable Hold-Down Gates enable the user to position adjustable fingers for uniform distribution of pressure on the UUT surface.

• Perfect for use on vacuum fixtures designed to test PCBs with open vias.
  
• Uniform pressure holds the PCB tight against top plate gasketing, while allowing the PCB to contact and deflect spring probes.
  
• Adjustable in X, Y and Z axes.
  
• Gate opens to 90 degrees.
  
• Gas spring holds gate open at any angle.
  
• Quick-release handle locks gate in position for testing.
  
• Adjustable hold-down fingers with Delrin tips are offered in four styles.
  
• Optional 1/2" riser frames and riser fingers accommodate tall components.
  
• Gate components are aluminum, steel and composite.
  
• Each gate is shipped completely assembled with instructions for installation on the fixture.
  
• Hold-down fingers are sold in packages of 10.
  
• An optional sealing package is recommended for applications that require isolation of probes from vacuum. The package includes the gate, a Twin-Seal™ gasket, and 3/8" G-10 stiffener plate.
  
• For high probe force applications, optional steel cross members are available for medium and large sizes.
