Cooling plate and front heat protection (NIR filter) for the Dx50, DT50-2 and DT80

Where to use?
For applications where ambient temperatures exceed the devices standard operating range – particularly in metal and steel processing.

What are the key benefits?

• Extended application range in high-temperature environments
• Improved measurement performance under thermal stress
• Protection against infrared radiation via heat protection filter

The cooling plate packaging contains no mounting accessories (screws etc.) and only one piece of cooling plate.
The reason for this is that the length of the screws depends on the number of cooling plates (and of course also on the thickness of the mounting plate).
The combination of a sensor and one of our mounting kits (e.g. BEF-AH-DX50 - Brackets | SICK or BEF-WN-DX50 - Brackets | SICK ) requires an ISO4762 M4 screw with a minimum length of 65 mm for a single plate and 85 mm for cooling plates on both sides of the sensor.

The cooling plates does not have separate mounting holes. Attachment is carried out using the sensor's through-holes (see exploded view no. 3).

It is glass with a coating for filtering infrared radiation. It must be used in combination with the cooling plates, as the active cooling effect comes only from the cooling plates. The heat protection filter protects therefore only passively from the heat (through the metal frame connected to the cooling plates). In addition, the NIR filter also prevents the heat radiation from damaging the sensor.
