Industrial Sensor Total Solutions

From selection to installation, from commissioning to operations — full-lifecycle services that let your sensors deliver real value

Why do you need total sensor solutions?

Industrial sensors are the "five senses" of automation systems — sensing the environment, detecting objects and collecting data. Yet many companies face real pain points in sensor applications: improper selection causing unstable detection, incorrect mounting positions causing false alarms and misses, and lack of maintenance shortening service life...

Kejie Technology provides total industrial sensor solutions. We don't just "sell sensors" — we start from your application scenario and deliver full-lifecycle services including selection advice, installation guidance, commissioning optimization and after-sales maintenance.

We work in close partnership with renowned sensor brands such as SICK, Pepperl+Fuchs, Keyence, Omron and others, and have rich hands-on field experience to recommend the most suitable sensor solution for your actual scenario.

Sensor Types

A full range of industrial sensors to meet different application needs

💡

Photoelectric Sensors

Detect the presence, position and shape of objects using light. Fast response and long detection range make them one of the most widely used sensor types.

  • Through-beam: separate emitter and receiver, detection range up to tens of meters
  • Retro-reflective: integrated emitter/receiver, easy installation
  • Diffuse reflective: no reflector needed, detects opaque objects
  • Fiber optic: high-temperature and corrosion resistant, ideal for harsh environments

🧲

Proximity Sensors

Detect metal or non-metal objects without contact. Long service life and fast response, suitable for position detection, counting and limit detection.

  • Inductive: detects metal objects, strong anti-interference
  • Capacitive: detects metal and non-metal, good for level detection
  • Magnetic: detects magnetic objects, commonly used for cylinder position
  • Ultrasonic: adjustable detection distance, suitable for transparent objects

Displacement Sensors

High-precision measurement of displacement, thickness, height and flatness, suitable for QC, positioning and measurement scenarios.

  • Laser displacement: micron-level precision, fast response
  • Eddy current: non-contact measurement of metal displacement
  • LVDT: contact measurement, high precision and stability
  • Draw-wire: long-range displacement measurement
