Laser Distance Meter with Communication
Dilas FT1600

  • Digital communication: Profibus-DP, Profinet, Ethernet Modbus TCP
  • Long range – High temperature targets
  • High accuracy +/ - 1mm
  • Design for steel industry conditions

Operating principle

The operation of the Dilas FT1600 is based on time of flight measurement. The sensor calculates the distance of the target surface using the time of flight of visible laser light pulses.
The measurement and sensor’s status are delivered on the digital communication.


The Dilas FT1600 is an autonomous sensor mounted in compact aluminium housing, IP66. The sensor can be ordered with mounting bracket or water cooling jacket.
For electrical connection, the sensor has three M12 connectors: one for the power supply and outputs, and two for communication.

The sensor can work as a standalone unit ; in that case, the setup is made from the control panel at the back of sensor. The parameters can also be set through the communication link when it is in use (on FT1604 only).

A digital display indicates the measured distance and two LED indicate status of sensor.

Two additional LED indicate the communication link status.

Features and benefits

The Dilas FT1600 is a digital, high resolution, non-contact laser measurement or detection sensor. The target may be hot or cold, stationary or moving. Dilas FT1600 measures on all non-shiny surfaces.

  • Measurement range: up to 50 m on natural surface, 500 m on reflective tape (see Accessories)
  • Target temperature: up to 1300 °C
  • Accuracy: up to ± 1 mm (1σ)
  • Digital communication: Profibus-DP (FT1602 -•C) or Profinet (FT1603 -•C) or Ethernet Modbus-TCP (FT1604 -•C)
  • Analog output 4-20 mA
  • Visible laser beam (class 2)
  • Autonomous sensor: ready to use, no calibration required
  • Integrated 5 digits display
  • Easy sensor setup with pre-set distances selection or extended configuration
  • Special modes optimized for Detection and Tracking
  • Water cooling & air purging ; optional heat shield (model FT160• - JC)

Typical applications

The Dilas FT1600 is well designed for applications of measure (dimensions, position) of slabs, billets, blooms, coils, and to detect product while passing in front of sensor. The product can be hot or cold.

Here are some examples:

      Slab dimension measurement                                                          Furnace entry : detection and position control


(1) Reflective tape Oralite ® 5200 white 1x1 m, useable between 50 m and 500 m.  

(2) Accuracy can be deteriorated by an intense ambient light, a reflecting or an absorbing surface, air turbulences.


  • Heat shield to protect sensor from direct radiation, only for FT160•-JC models.
  • Termination resistor for Profibus (male connector M12, B-coded, ref. 2536756).
  • Communication cables with protective steel braid: see separate datasheet.
  • Reflective tape Oralite ® 5200 white 1x1 m (ref. 2636434), useable between 50 m and 500 m. Can increase the reflectivity of your surface to improve response time of Dilas FT1600 in case of fixed target.
