Gain a thorough grasp of these 10 types of sensors, and you will secure half the success of your non-standard automation equipment projects.
Latest company news about Gain a thorough grasp of these 10 types of sensors, and you will secure half the success of your non-standard automation equipment projects.

It is often claimed that non-standard automation equipment amounts merely to “assembling building blocks” — cylinders, motors, linear guides and PLCs. Nevertheless, the factors that decide if equipment can operate steadily, resist dust and oil pollution on-site at the client’s facility, and function without faults under set cycle times usually lie in the selection and commissioning of those inconspicuous sensors.

Today, we fully dissect the ten core sensors widely used in non-standard automation. Gain a thorough command of them, and your equipment will gain half the guarantee for stable operation.

Photoelectric Sensors

The "eyes" of production lines and masters of long-distance detection.
Core functions: Production line counting, pallet arrival detection, and long-distance presence sensing of materials.
Field practical tips:
  • Through-beam type: The most reliable option, ideal for dusty environments. However, precise alignment between transmitter and receiver is required during installation.
  • Retro-reflective type: Easy to deploy with single-side mounting. Nevertheless, dirt on the reflector causes false triggers, so regular cleaning is necessary.
  • Diffuse-reflective type: The most widely used variant. Its sensing range is heavily affected by object color; effective range drops significantly for black targets. When selecting models, evaluate performance based on at least 60% of the rated sensing distance.
Having persistent counting errors on conveyor lines? First check whether the sensor spot is too large, or the gap between adjacent products is insufficient. Adding a light barrier or switching to laser photoelectric sensors with smaller light spots will deliver immediate improvements.

Fiber Optic Sensors

The "micro scouts" for compact workstations
Core functions: Detection of tiny components within confined spaces and precision positioning.
Field practical tips:
  • Calibration trick: The threshold on the fiber amplifier cannot be set arbitrarily. The two-point teach-in method is recommended: record the light intensity values for both target-present and target-absent conditions, then set the threshold slightly offset from the midpoint for better anti-jitter performance.
  • Bending radius: Never form sharp bends on fiber cables. Sharp folds break the internal light path and cause severe, frustrating signal attenuation.
  • Type selection: Glass fiber withstands high temperatures; plastic fiber is low-cost yet vulnerable to oil and heat. Match the type to your working environment.
Ordinary photoelectric sensors fail to check whether spring lock washers are missing from assembly. Run fiber optic cable through the gripper, and you will achieve stable, accurate, reliable detection.

Color Sensors

The color recognition specialists on sorting lines
Core functions: Material color differentiation, color mark positioning, and error-proof sorting.
Field practical tips:
  • Confusion within similar color families: Dark red vs light red, dark blue vs black often lead to misjudgment. Prioritize models adjustable for color tolerance during selection.
  • Severe ambient light interference: Light shielding is mandatory, or opt for sensors equipped with ambient light compensation.
  • Most reliable application: Color mark positioning (e.g., black marks on packaging film), delivering far better stability than standard photoelectric sensors.
Typical applications: Electrode sheet sorting for batteries, pill color classification, color error prevention for automotive wiring harness
