IFM DI523A is a compact speed-monitoring evaluation unit designed for industrial and hazardous-area applications. It uses an inductive measuring principle and provides a configurable speed-monitoring function. The unit has an M30 × 1.5 threaded housing with an 80 mm length. It supports IO-Link communication and has IECEx and ATEX approvals for specified applications. The IFM datasheet specifies a 5–18000 impulses/min maximum damping frequency range.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The DI523A provides integrated sensing and evaluation for rotational speed monitoring. Its inductive sensing principle allows reliable detection of metallic targets. The switching point can be adjusted through a multiturn potentiometer or IO-Link. This provides flexibility during commissioning and machine setup. The unit is designed for reliable operation in industrial environments.
The DI523A has IECEx and ATEX markings for specified hazardous-area applications. Its IP65/IP67 protection supports use in demanding environments. The operating temperature is specified as -20 to 60°C. The device can be used where appropriate certified speed monitoring is required. Installation must comply with the relevant hazardous-area requirements.
IO-Link provides device identification, process data, diagnostics and parameterisation functions. The device uses COM2 transmission at 38.4 kBaud. Its minimum process cycle time is 3.2 ms. These features support integration into modern automation architectures. The device also provides LED indication for switching and input status.
