-MA
0°C to 60°C
-HA
0°C to 180°C
The high ambient temperature sensing head on -HA models is capable of withstanding
temperatures of up to 180°C without cooling. It is available with 20:1 optics.
There is no need to supply cooling air or water, and the miniature sensing head is much smaller than
bulky, cooled sensors.
