More Information

Overview Manuals Selection Installation Service Product Applications

Features:

  • Integrated AS-i node: Antenna and evaluation electronics share one compact housing for direct network connection.
  • Contactless identification: Tagged carriers can be recognized without mechanical contact or optical line of sight.
  • Local diagnostics: Multicolor indicators assist with supply, tag communication and network-error checks.
DTA101 is intended to read compatible LF RFID tags as carriers move through a controlled sensing zone.

The integrated AS-i interface reduces the need for a separate local evaluation module at the read point.

Read reliability still depends on tag orientation, spacing, surrounding metal and correct network commissioning.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Exact identity: Require DTA101 and its read-head designation on the offered unit.
  • Mechanical envelope: Confirm the existing bracket and connector clearance.
  • Frequency family: Keep the replacement within the documented LF system architecture.
  • Evidence package: Retain the OEM DTA type/profile table with the quotation.
  • Bracket retention: Keep the original mounting hardware with the antenna location.
  • Face protection: Prevent tools or carriers from striking the sensing face.
  • Connector integrity: Seat and secure the A-coded M12 connection.
  • Cable support: Relieve cable load so it is not transferred to the connector.
  • Housing inspection: Record impact, abrasion or connector damage before testing.
  • Known-part record: Keep a verified tag identifier in the maintenance file.
  • Bracket record: Photograph the antenna position before mechanical work.
  • Replacement history: Record the removed and installed DTA model codes separately.
  • Routing conveyors: Identifies workpiece carriers at decision points.
  • Assembly tracking: Reads pallet identities for recipe or station selection.
  • Material-flow control: Reports tagged containers to an AS-i-connected control system.
  • Legacy RFID maintenance: Restores a documented LF read point without changing the network architecture.
Description
At a material-flow or production checkpoint, DTA101 captures identification data without a mechanical contact operation. This supports automatic item recognition where repeated physical switching would add wear or handling complexity.

DTA101 combines a low-frequency RFID read head and AS-Interface connection in one rectangular housing. The unit places the reading function and field-network interface at the same identification point.

Through its AS-i connection, DTA101 presents the read result as an addressable field-network function. This lets the machine sequence use identification data without adding a separate serial interface at the checkpoint.
Technical notes
Isolate the AS-i segment according to the approved network procedure before removing DTA101. Photograph the product label, bracket and connector orientation, retain the mounting hardware and protect the antenna face from impact. After installation, secure the M12 connection and record the replacement identity in the machine file.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
DTA101 sees a tag when stationary but misses it on the conveyor. Which application factor should be tested first?
Recreate the real speed, orientation and closest approach, then check mounting rigidity and read margin. A static bench test does not prove reliable identification on a moving carrier.
The yellow tag LED on DTA101 operates, but the PLC receives no identity. Where should diagnosis continue?
Verify the AS-i address, network communication, controller mapping and expected data handling. The local read indication separates the tag interaction from the upstream communication path.
A steel bracket was added beside DTA101 and read range declined. What condition should be tested first?
First restore the manufacturer-documented tag and antenna geometry, including the applicable metal-clearance condition, and repeat the same read test. Treat the bracket as a test variable, not as a proven cause.
Can DTA101 write configuration data to a transponder during commissioning?
No. The exact model is a read antenna. If writing is required, select and validate an appropriate read/write head and confirm its network and tag compatibility.
A replacement DTA101 appears at the wrong AS-i node after installation. Should the PLC program be changed?
First assign or restore the documented device address and confirm the wiring position. Changing the program to follow an accidental address can create future maintenance confusion.
A DTA100 is offered for a failed DTA101 because the housings and dimensions match. Is it the same functional replacement?
No. The ifm catalogue identifies DTA100 as a read/write head with AS-i profile 7.4 and DTA101 as a read head with profile 7.3. Preserve the required head function and profile.
