Air-operated robotic compliance unit / collision sensor U1-050

Product overview

• Universal compliance: Patented mechanism provides simultaneous X‑Y lateral, X‑Y‑Z rotation and Z compression compliance to overcome significant misalignment between tool and workpiece.
• Pneumatic reset: Pneumatically actuated piston returns the unit to a repeatable center position; springs maintain minimum preload.
• Adjustable stiffness: Compliance stiffness is tuned by varying pneumatic pressure to the reset piston for application‑specific behavior.
• Integrated sensing: Optional compliance sensor monitors internal piston proximity (PNP or NPN).
• ISO mounting pattern: Direct attachment to many robots without adapters.
• Flexible configurations: Options include PNP/NPN sensor, rubber boot for environment protection, and custom tool‑plate bolt patterns.
