Work Supports / Double Acting, Position Sensing
Top Flange
Return Position Sensing for D/A Top Flange Work Support The Double Acting Return Position Sensors use air pressure to communicate that the work support has retracted and that the fixture can be unloaded/loaded. Sensor monitors work support position to prevent crashes in automated systems. Fail safe design requires air pressure to build before sensing the retracted position. Dual wipers keep chips and debris from invading support. Pressure Relief Vent keeps unit sealed and free from foreign material. Air connection through face sealed O-ring of top flange body or externally plumbed through NPT ports on sensor housing. Top flange body style allows for hydraulic connection through face sealed o-rings or through SAE ports. Aluminum sensor housing is Black anodized for superior corrosion resistance. Optional in-port flow control is a meter-in device with reverse free flow check valve. Optional in-port sequence valve is a sequencing device with reverse free flow check valve.

* Support capacities are listed at 5,000 psi maximum operating pressure. Support capacities for other pressures must be determined by consulting the capacity graph at the start of Section B. ** Use Return Position Sensor to monitor retracted position only and not plunger advance or plunger lock. *** In-Port valves requires the use of manifold mount ports. Device Operation The return position sensor unit requires continuous regulated air pressure. In the retracted position, air pressure will build in the system to the regulated set pressure. The air logic switch detects “retracted” pressure and signals that work supports have retracted. When the work support extends, the internal check is opened and air vents from the device. The system air pressure falls to the “extended” pressure and the air logic switch resets. When the support is then retracted, the internal check is closed and air pressure again builds to regulated value. Air pressure switch detects “retracted”pressure and again signals device is in retracted position.

The workpiece must be positioned inside this window to prevent part ejection. ** Shuttle Stroke “C” is the stroke the shuttle travels to position the work support plunger relative to the workpiece. The shuttle moves the full range of this stroke every cycle. *** The difference between “C” and “B” (C-B) equals the minimum distance the plunger is below the workpiece in the retracted position.
