IFM DI5021 is a compact speed monitoring unit designed for detecting abnormal speed conditions in rotating and linear machinery. It belongs to the DIA3010 family and uses inductive sensing for non-contact target detection. The device is designed around a 10 mm nominal sensing range and operates from a 10–36 V DC supply. Its compact threaded housing supports convenient machine installation. The monitoring function can be used to detect underspeed and blocking conditions. DI5021 is suitable for industrial equipment where reliable speed supervision is required.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
DI5021 evaluates the movement of metallic targets without direct mechanical contact. This makes it suitable for monitoring rotating shafts and machine mechanisms. The sensing method helps minimize mechanical wear. The device can identify speed conditions that fall below the configured limit. It can also be used for detecting blocked movement. This provides an effective solution for machine protection.
The device is designed for continuous operation in industrial automation systems. Its threaded housing allows convenient mounting near the monitored target. The compact format helps simplify machine integration. Electrical protection functions help support reliable operation. The unit can be connected to a machine controller through its switching output. This allows automated response to abnormal speed conditions.
Non-contact speed detection reduces mechanical contact and associated wear. The compact design simplifies installation and replacement. Status indication can help maintenance personnel identify operating conditions. Configurable speed monitoring supports different machine requirements. The device can be used as part of preventive machine monitoring. DI5021 provides a practical balance between simple installation and reliable speed supervision.
