Industrial Applications

1. Automotive Manufacturing - Position Detection in Welding Cells

This sensor is ideal for precise position detection of metal parts and fixtures within automated welding cells in automotive manufacturing.

Problem Solved

The sensor's 8 mm flush sensing distance, IP68/IP69K rating, and high shock/vibration resistance ensure reliable and accurate detection in the harsh, electromagnetically noisy, high-temperature environment of a welding cell where coolant, weld spatter, and vibrations are common. The -40 to +85 °C extended temperature range accommodates varying workshop temperatures.

2. Food & Beverage Industry - Conveyor System Object Tracking

Suitable for tracking metal containers, cans, or components on conveyor belts in food and beverage processing lines, enabling reliable detection of product passage.

Problem Solved

The critical IP68/IP69K rating protects against frequent high-pressure washdowns with hot water and cleaning agents common in hygienic food and beverage environments. The brass, nickel-plated housing resists corrosion. Its 8 mm flush sensing distance allows for discreet integration without obstructing product flow, and the -40 to +85 °C temperature range handles both refrigerated and heated process areas.

3. Heavy Duty Mobile Equipment - Hydraulic Cylinder End-Position Sensing

Integrate this sensor into hydraulic cylinders on construction machinery or agricultural vehicles to detect the fully extended or retracted position of metal piston rods.

Problem Solved

The wide 10-60 V DC operating voltage is compatible with typical 12V or 24V vehicle electrical systems. The IP68/IP69K rating provides robust protection against dirt, dust, mud, and water ingress prevalent in outdoor mobile applications. High shock and vibration resistance ensure longevity despite rough terrain and heavy operation, while the extended temperature range supports diverse climates.
