SICK DT20 Hi Series Distance Sensor, IP65, 2.5ms Response Time - DT20-P214B

This distance sensor is a Compact laser-based displacement device designed for industrial automation and measurement tasks. It operates from a DC supply and delivers an analogue current signal for precise distance monitoring across a mid-range measuring span. Housed in a robust metal enclosure with ingress protection, it is intended for panel mounting and integration in control systems where repeatable, short-latency distance feedback is required.

Features & Benefits

• Measures 100mm–600mm range for mid-distance detection and control
  Repeatability greater than or equal to 0.5mm to support consistent position monitoring
  Linearity ±2mm for predictable analogue scaling in closed-loop systems
  Response time 2.5ms enabling Rapid process feedback
  5-pin M12 panel-mount connector for secure electrical interfacing

**Applications**

• Suitable for material-handling position verification on conveyors
  Ideal for thickness or displacement checks in assembly lines
  Used for height control in pick-and-place automation
  Can be used for distance-based quality inspection in production
  Suitable for integration with machine-control systems requiring current output

What light source does it use and are there safety considerations?

It uses a visible red laser and meets laser class 2 safety standards under IEC/EN 60825-1, which limits exposure risk for normal use.

How does the sensor cope with varying ambient light?

The receiver tolerates artificial lighting up to 3,000 lx and direct sunlight up to 10,000 lx, maintaining measurement stability under bright conditions.

What are the electrical supply limits and protection features?

It accepts 10V–30V DC operation, includes reverse-polarity protection and is designed for operation in short-circuit-protected networks.

How is the output configured and what resolution is available?

The analogue output is a current loop of 4mA to 20mA with 12-bit resolution, and a multifunctional input enables external teach-in or laser disable.

What environmental and mechanical tolerances should be expected?

It operates between –20°C to +55°C, meets IP65 for dust and water protection, and is built in a zinc die-cast metal housing for industrial use.
