TuffGrip™ Position Sensing Work Supports the positive retraction of Double Acting, and senses the retraction and lets you know it, is now available...
Use TuffGrip™ return position sensing units in any automated system when it is critical to know that the work supports are retracted before beginning the unload/load cycle. Whenever an extended work support could cause a machine, robot, or other tool crash, the position of the work support has become critical. TuffGrip™ offers the extra measure of vigilance that could mean the difference between profit and loss.
The TuffGrip™ Position Sensing has the same positive return as Vektek’s other double acting supports and you no longer need ancillary devices to insure part retention. Once retracted the "all clear" feedback can be communicated back to the machine controller before unloading/loading the part. Your project stays on time and on target.
We are already using TuffGripTM double acting work supports, why would we need to use the return position sensor?
Use the return position sensor in any automated system where knowing that the work supports are retracted before the unload/load cycle begins is critical. During a part unload/load, if an extended work support could cause a crash, the position of the work support should be monitored and feedback given to the machine logic so it knows all is clear before unloading/loading the part.
Does the Return Position Sensor also tell me that the work support is extended and locked?
No, the return position sensor only communicates that the work supports have retracted. Even though the pressure drops when the supports extend, it does not indicate that all the work supports have extended or are locked.
Can I add a Return Position Sensor to my existing double acting work support?
No, adding the return position sensor requires a return position sensor body as well as a longer plunger and contact spring. Adding the return position sensor also increases the length of the work support from the mounting flange to the contact bolt. Work supports with the return position sensors should be ordered new from Vektek, Inc. at
How many work supports with Return Position Sensors can I put on one pneumatic circuit?
The maximum number of return position sensors in one circuit is a function of the circuit design and pressure drop over the length of the circuit path. Vektek has tested ten devices plumbed in parallel with excellent results.
What if I want to run a different pneumatic pressure switch than what Vektek
Any programmable pneumatic switch that interfaces with the machine tool logic can monitor air pressure in the Return Position Sensor circuit.
Can I design my pneumatic circuit to be series rather than parallel?
Yes, but it is not recommended. Plumbing the return position sensor in series will create a much greater pressure drop along the length of the circuit and will reduce the ability of the pressure switch to see an extended support at the furthest point in the circuit.
Is it okay to route my air through a rotary union?
Yes, size the rotary union so that there is a separate path for the air circuit.
Do I need a pneumatic pressure switch for each work support on my fixture?
No, connect all the work supports (that are on the same hydraulic circuit) with an air circuit feeding the return position sensor to one pneumatic pressure switch.
