The IFM MQ2004 is a weld-field-resistant magnetic sensor with IO-Link communication, programmable switching functions and condition-monitoring capability. It provides a 5 mm sensing range and supports PNP/NPN as well as normally open/normally closed parameterisation. The 0.3 m cable configuration supports compact installation, while its non-stick coating and robust metal sensing face make it suitable for welding systems and demanding industrial automation applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MQ2004 combines magnetic position sensing with diagnostic functions for demanding industrial applications. It is designed to operate reliably in environments affected by weld fields and weld slag. Its IO-Link interface allows parameterisation and access to diagnostic information. The 0.3 m cable configuration provides a compact installation option. The rectangular housing and metal active face support robust machine integration.
The sensor provides a 5 mm sensing range and programmable PNP/NPN electrical design. Its output function can be configured between normally open and normally closed. IO-Link communication supports parameterisation and diagnostic functions. The non-stick coating helps reduce weld-slag adhesion, while weld-field resistance supports reliable operation around welding equipment. The sensor operates from 10 to 30 V DC.
MQ2004 is suited to automated welding and manufacturing environments where sensor contamination and electromagnetic interference can be challenging. Its condition-monitoring capability helps support preventive maintenance. The robust metal active face provides resistance to impact. The sensor supports flexible machine integration through programmable outputs and IO-Link. Its 0.3 m connection configuration is convenient for compact machine layouts.
