CONVUM PQ Series | Non-Rotation Pads for Precision Handling

• Anti-Rotation Structure: Built-in rotation stop keeps the cup from twisting at the mount—stable alignment and precise placement.
• For Smooth / Deformable, Orientation-Critical Parts: Ideal for thin sheets, soft media, and parts requiring a fixed orientation (labels, keyed terminals, etc.).
• Size Range: ø6 / 8 / 10 mm.
• Material Options (Code | Material | Key traits):
  • N | NBR: general-purpose, oil resistant.
  • S | Silicone: soft, conformable, low marking.
  • U | Urethane (PU): wear resistant, quick rebound.
  • F | FKM (Fluoroelastomer): heat & chemical resistant.
  • NE | Conductive NBR: ESD conductive.
  • SE | Conductive Silicone: ESD conductive, soft.
• Applications: Precision electronics assembly, orientation-specific labeling/placement, thin-sheet handling, stations where rotation must be prevented to avoid scuffing or misalignment.

Q1: What parts and use cases are PQ pads best for?
A: Precision electronic parts, thin sheets, and orientation-critical components—such as those with keys, locating grooves, or directional marks—where rotation must be prevented during handling.

Q2: What is the key difference between PQ and standard pads?
A: PQ features a non-rotation structure at the mount, preventing the cup from twisting during pick and place. This improves positional accuracy and yield.

Q3: Are PQ pads suitable for high-speed automation?
A: Yes. Their lightweight design supports fast pick-and-place. For best stability, tune vacuum orifice and motion profiles (accel/decel) to your equipment.

Q4: What sizes are available?
A: ø6, ø8, and ø10 mm. Select based on part size, effective contact area, and payload requirements.

Q5: Can PQ handle rough or stepped surfaces?
A: PQ is optimized for smooth, orientation-sensitive parts. For rough/uneven surfaces, consider PD (foam) or PL (multi-bellows) series for better conformity and sealing.

Q6: What material options are offered for PQ?
A: N (NBR), S (Silicone), U (Urethane), F (FKM), NE (Conductive NBR), and SE (Conductive Silicone). Choose by needs such as oil resistance, softness/conformability, wear resistance, chemical resistance, or ESD conductivity.
