Inductive Proximity Sensor survives abusive welding applications.

Press Release Summary:




Offered in PNP NO output configuration with micro connector, BunkerProx® self-bunkering M18 sensor has nominal range of 4.0 mm. Thickness of housing enhances ability to withstand repeated mechanical impact, while housing itself also serves as intermittent heat sink to shield sensor electroncs. Other protection features include frontal impact deflection ring, ceramic face resistant to melting and burn-through, slag-resistant coating, and weld-field immune electronics.

New BunkerProx® Reduces Sensor Impact Failure



Florence, KY: In abusive welding environments, "bunkering" describes the technique of mounting sensors into tough metal brackets for impact protection. However, many sensor applications have not been properly bunkered, resulting in repeated (and costly) failures from impact damage. Often, it is too difficult and time-consuming to retrofit these applications with adequate bunkering protection.

Enter Balluff's BunkerProx: a rugged, "self-bunkering" M18 inductive proximity sensor specially designed to survive longer in abusive welding applications without external protection. The key to the BunkerProx design: a strong, massively thick housing that boosts the ability to withstand repeated mechanical impact. The extra-thick housing also serves as an intermittent heat sink to shield the sensor electronics from the intense heat of red-hot weld slag.

A frontal impact deflection ring helps protect the high-temperature ceramic face from impact damage during part loading and unloading. The ceramic face also resists the melting and burn-through that can short out the sensing coil of standard proxes, killing them instantly. Additionally, the all-important sensing coil is reduced in diameter compared to standard M18 sensors, providing a perimeter "crush zone," so that incidental corner impacts don't result in immediate coil damage and loss of sensor function.

An unusually thick connector/barrel junction helps to eliminate connector failures from excessive shock, vibration, heavy contact, or undue cable stress. To repel hot weld slag and prevent it from sticking, the BunkerProx is fully coated with slag-resistant material, while weld-field immune electronics eliminate false signals during the welding cycle. Offered in a PNP N.O. output configuration with a micro connector, nominal sensing range for the BunkerProx is specified as 4.0 mm.

BunkerProx gives plant maintenance personnel a new tool to combat excessive sensor failure. Installing BunkerProx into impact-prone weld fixtures can help reduce unplanned downtime, cut sensor replacement costs, and shave maintenance expenses. The increased profitability, higher throughput, and lower operating costs can be dramatic.
