Balluff's 
BunkerProx® Inductive Sensor
For high impact welding applications
Balluff’s new BunkerProx® sensor represents a new concept in inductive sensor protection.
Intended for the most rugged and physically abusive welding and metalworking applications, BunkerProx incorporates a robust design that can take the abuse of heavy part loading and welding operations.
The Balluff BunkerProx Advantages:
•Thick metal housing protects sensor against mechanical damage
•Unique one piece connector/body eliminates connector failures
•Thick sensor walls provide intermittent heat sink, protecting internal electronics
•Frontal-impact deflection ring protects face from repeated impact
•Ceramic face resists weld spatter burn-through up to 2200°F
•Weld spatter-resistant coating repels weld spatter build up
•Weld Field Immune electronics provide error free operation
Application example:
BunkerProx in an abusive weld load cell lasted 10 times longer than previous weld sensor
