DI604A Compact Speed Sensor
The DI604A is a manufacturer-published ifm model or family identifier for a compact speed sensor. This page gives engineers, maintenance teams and buyers a clear reference for identifying the device and preparing a technically complete enquiry.
Final suitability cannot be established from the photograph or short model name alone. Confirm the full ordering code, actuator or sensing arrangement, contacts and control voltage, enclosure material, cable entries, temperature range, ingress protection and required approvals for the exact version.

Application and selection
This device belongs to a conveyor, bulk-material handling, crane, hoist or rugged industrial switching range. Define the monitored fault or position, the necessary alarm/interlock/stop response and the environmental duty before selection. For replacement work, record the complete nameplate, terminal state, mounting centres, actuator direction and wiring before removing the old unit.
Installation and commissioning
Mount the device on a rigid support, preserve the manufacturer’s permitted movement and overtravel, use suitable cable glands and earthing, and protect wiring from mechanical damage. A safety or protection switch must not become a belt guide, step or structural stop.
Commission the full cause-and-effect chain: actuate the field device safely, verify the controller input and intended alarm or stop, check manual reset where fitted and confirm that reset cannot cause an unexpected restart. Functional-test intervals should reflect machine risk, contamination, vibration and service conditions.
Official source
