Original - Senvex sprue gripper # 790

This is our favorite gripper for many reasons. The internal jaw mechanism is constructed of hardened steel components for a maintenance free life exceeding 5 million cyles. Sprue fingers are made of hardcoat anodized machine grade aluminum (replacement finger kits are available - replacement does not require disassembly of the gripper). The integrated sprue finger design allows a wide range of sprue diameters to be gripped. Interlaced serration securely grips small diameter sprues, while the cradle design assures that even large diameter sprues won’t twist out. Dual sensor slots allow 2 sensors to mount on the gripper . This gripper offers the highest grip force in a compact and lightweight body at an excellent price.

Best Value - Senvex sprue gripper # 1473

We consider this to be one of our best values. At $129, no other brand of gripper comes close. It provides high grip force in a compact, light weight body.Sprue fingers are made of anodized extruded aluminum - replacement finger kits are available (replacement requires disassembly of the gripper). The integrated sprue finger design allows a wide range of sprue diameters to be gripped. Interlaced serration securely grips small diameter sprues, while the cradle design assures that even large diameter sprues won’t twist out. NOTE: This gripper is very sensitive to sensor positioning. Although sensing is possible with these grippers, we suggest those wanting maximum sensing capabilities to use either the #790 or #1880.

Senvex Sensor Finger # 1880

Newly improved! Our new Sensor Finger is based on the popular 1473 gripper, but with a sensor mounted on the finger. The finger mounting makes it much easier to set up the finger target and sensor, and eliminates the typical ‘hide and seek’ process of sensor set-up. We consider the Senvex Sensor Finger to be an excellent way to positively confirm 'sprue is gripped'. In addition to the finger sensor, there are 2 more sensor slots on the gripper body that can also be used if additional sensing is needed i.e. use one to confirm gripper open and the other to indicate gripper fully closed (sprue missed). Other features are the same as the 1473.

Senvex Mini Sprue Gripper # 1879

We like the Senvex Mini sprue gripper for a number of reasons. It provides a higher gripforce than other similarly sized sprue grippers, and we have found that the design of the finger teeth holds sprues better than those of other small sprue grippers. In addition, the finger mounted sensor on the Sensor Model (1878) makes it much easier to set up the finger target and sensor, and eliminates the typical ‘hide and seek’ process of sensor set-up.

Senvex Large Diameter Sprue Gripper Body # 1476
Large Diameter Sprue Fingers # 5288

An excellent choice for gripping large sprues, this gripper features a larger finger set to grip sprues from Ø12mm to Ø25mm. Fingers are 25 mm wide to provide extra surface contact, and cross hatching on the gripping surface prevents the sprue from rotating while it is gripped. The body features the same high quality construction as our 'original' SENVEX sprue gripper, that has proven so reliable since its introduction in 2002.
