13.2 Area of application
The LMA/B is a fully integrated sensor for industrial use. It is suitable for the detection of hot and cold
objects and may be used for general applications. Due to its insensitivity to radiation from other
sources, the LMA/B can be used for material distance measurement also in furnaces.
The LMA/B offers different interfaces to transmit the detection result to the subsequent processing
unit, as for example to a PLC.
Thanks to its sturdy construction in compact stainless steel housing, the LMA/B can operate even
under harsh ambient conditions. A distance range of up to 150 m can be achieved (see 14.3
–
Distance range).
14 Technical Data
14.1 Equipment Data
Proxitron LMA/B sensors are available in different versions. Please refer to the equipment label or to
the appropriate datasheet for details of the specific equipment.
14.2 Connection
A 12-pole plug is available on the LMA/B in accordance with M12 industrial standard. This connection
provides for optimal shielding and a high IP rating. In plugged condition, connector meets protection
level IP 67.
Suitable female connectors with cable in different lengths are available. Please ask the manufacturer.
