DL100-21AA2101 SICK Dx100 DL100 Pro SSI Laser Distance Sensor
DL100-21AA2101 is a high-precision long-range sensor from the SICK Dx100 DL100 Pro family. It uses phase shift optical time-of-flight measurement. The unit reaches 100 m on Diamond Grade reflective tape. An SSI fieldbus interface delivers Gray or binary position data. It tracks motion up to 15 m/s and acceleration up to 15 m/s². This model targets automated storage and retrieval systems, cranes, and dynamic positioning axes.

FAQ
Q: Can the DL100-21AA2101 measure without reflective tape?
A: No. The 100 m range needs Diamond Grade reflective tape. Natural surfaces give much shorter range. Always confirm the target type before ordering.
Q: How do I match SSI settings to my controller?
A: Check code format, bit count, and clock frequency. Set Gray or binary on both sides. Keep bus cable length within the controller limit. Test with a slow axis move first.
Q: What causes unstable readings on a stacker crane?
A: Dirty tape, weak signal level, or loose mounting are common causes. Clean the tape and recheck alignment. Review signal attenuation data in the display menu.
Q: How do I know when the laser diode is aging?
A: The sensor tracks diode aging internally. Check the condition monitoring values during service. A falling signal level at short range points to aging or window contamination.
Q: What should I verify before buying a used DL100-21AA2101?
A: Confirm part number 1052684 and SSI interface type. Ask for signal level and diode aging records. Check the PMMA window for scratches. Oiltech Controls verifies units before shipment.
