Collision Sensors for Arc-Welding

QS_AW

QuickSTOP™ is a dynamically variable collision sensor that operates on air pressure.
Upon impact, the air chamber is opened, and the shutdown signal is immediately sent to the system controller.

Advantages

• Dynamically Variable Trip Points
o Programmable sensor at all speeds of operation
• Permanent Repeatability
o Non-compressive, metal-to-metal seal
• Senses Angular and Compressive Forces
o Protection in the X, Y, and Z axes
• Monitors Performance Readiness
