Pin Locator Clamps (PLC) and Single Finger Clamps (SFC)


BTMs’ Pin Locator Clamps and Single Finger clamps are used in stationary part nests, welding fixtures, transfer systems, robot end effectors and numerous other clamping applications. These clamps locate and hold the work while other operations are performed.

BTMs’ PLC Clamps are offered with a wide range of round and diamond pins. These locating pins range from 42mm to 18mm in diameter. BTMs’ SFC Clamp fingers also come in special shapes and sizes for your application. The PLC and SFC series of clamps offers a constant force of 300lbs through the entire stroke. They can clamp on the thinnest material to material exceeding 25mm thick by utilizing a “donut” rest block. This series of clamps may also be altered for use as a trap for applications involving painted or show surfaces.

BTM PLC & SFC clamps are available in a variety of configurations. The cylinder bodies are all standard. The locating pin, clamp finger, and locating rest block “donut” can be custom made to fit the customer’s specific applications.

BTM's Locking Pin & Locking Single Finger Clamps are ideal for locating & holding production material and are used in a variety of manufacturing areas including automotive & refrigeration. These clamps can be used in conjunction with robot end arm effectors to produce state of the art automation production capabilities.

    How it works

    How BTM Pin Clamps work:

    plc_step1 plc_step2 plc_step3 plc_step4
    Part Loaded over Pin Finger Extends out of Pin Finger Clamps Part

    How BTM Single Finger Clamps work:

    Part is loaded over the retracted finger and rests on the rest block ("donut"). Finger swings in the direction of clamping surface with 5mm of rotational travel. The finger then has up to 10mm of straight line travel to the clamped position.
