New miniature 2D laser triangulation sensor

Jon Lawson

A new matchbox-sized 2D laser triangulation sensor from Riftek, represented in the UK by Ixthus Instrumentation, combines a choice of red or blue laser sources with a power output of 0.95mW for measurement ranges up to 500mm and linearity to 0.05% of range. Easily adapted for measurement of thickness, dimension/displacement, form and profile as well as object sorting etc., the new RF602 series laser triangulation sensors are particularly aimed at applications where restricted space or minimal weight are important machine design requirements.

The new RF602 series includes six sensor models with measurement ranges from 10 to 500mm and base distances from 20 to 105mm. Full range resolution is 0.01% (0.02% for 105/500 version) and temperature drift is 0.02% of the range per °С. These laser safety class 2 sensors have a maximum sampling rate of 9.4 kHz that suits high speed/high throughput measurement. A red laser source is available for general use or an optional blue UV wavelength version is offered for applications where high temperature objects or organic materials are measured.

The new RF602 joins a family of laser sensors from Ixthus that share a common PC-based service software platform. A wide range of configuration parameters allow flexible parameter set-up and digital measurement reading via RS232 for single sensors or RS485 for multiple sensors.
Measured data output may also be can also be read through 4…20 mA and 0…10 VDC outputs. 

The sensor is housed in a robust IP67 rated anodised aluminium housing with a high strength glass window for maximum durability. With a -10 to +60 ⁰C operational temperature range and vibration and shock ratings that will suit moving machinery applications, the RF602 is well suited to
heavy industrial use but can be equally practical for less severe environmental conditions. Cable connection with flying leads is standard
and the diminutive 30.5x45x17mm (wxhxd) housing includes front fixing holes for straightforward mounting.
