40 × 40 mm Square HF RFID Read Head, RS485 Modbus RTU: overview
The IH-130 is a 13.56 MHz RFID read head in a square 40 × 40 × 45 mm housing, for production-line identification points where a flat sensing face suits the layout better than a threaded barrel: beside a conveyor, on a fixture plate or below a pallet stop. It reads ISO/IEC 15693 and ISO/IEC 14443A tags on pallets, workpiece carriers, trays and tool holders.
Rated read distance is 0–80 mm depending on the tag, and about 60 mm with a Ø30 mm industrial tag. That gives more clearance between head and tag than the compact IH-140, which helps where carriers wobble or vary in height. The integrated PCB antenna sits behind the target-marked front face, which makes it easy to line the head up with the tag path during installation.
The IP67 housing is rated for operation from –40 to +70 °C and for ESD of ±10 kV air and ±8 kV contact discharge, so it holds up on machine frames and in wet or dusty line areas.
Integration notes
Power the head from 24 V DC; consumption is 2 W at most. It communicates over RS485 at 9600–115200 bit/s using Modbus RTU, for direct connection to a PLC serial module or to an RS485-to-Ethernet gateway. The M12 connector takes a female-connector cable harness. An orange LED blinks to show operating status, firmware is updated over the serial port, and an API kit with C, C# and Java sample programs is available. The complete set weighs about 120 g.

IH-130 FAQ
What read distance should I plan for?
The head is rated 0–80 mm depending on the tag, and about 60 mm with a Ø30 mm industrial tag. Metal around the sensing face reduces range, so check the gap with a sample in your fixture.
When should I choose the IH-130 over the M30 IH-120?
Choose the IH-130 when a flat, square sensing face is easier to mount than a threaded barrel, or when you need a fixed rating of about 60 mm with a Ø30 mm tag (the IH-120 is rated 45–60 mm depending on build). Both use RS485 Modbus RTU, 24 V DC and an M12 connector.
Does it support Modbus TCP?
Not directly. The IH-130 has a single RS485 port that carries Modbus RTU. For an Ethernet network, place an RS485-to-Ethernet gateway between the head and the PLC, or use the IH-110 reader, which has Modbus TCP built in.
What cable does it use?
An M12 female-connector cable harness carrying 24 V DC and the RS485 pair. Ask for the pin assignment and specify the cable length on your RFQ.
Can the head write data to tags?
The published rating covers reading only. If your process must write lot or step data to the tag, contact us to confirm write support and write distance for your tag type, or use the IH-110, which is rated to write at up to 100 mm on ISO 15693.
