More Information

Overview Manuals Optical Link Data Interface Environmental Fit Applications

Features:

  • Contactless communication: Serial data crosses a moving gap without slip rings or festoon data cable.
  • Long optical range: The 150 m boundary supports large travel paths when alignment is maintained.
  • Cold-area heating: The integrated heated operating mode extends use into low-temperature installations.
ISD280-1112 is the optical bridge in a point-to-point industrial serial or PROFIBUS link.

Two aligned units exchange data through an 860 nm infrared beam while the connected controllers continue to use their wired interfaces.

Performance depends on clear sight, mounting rigidity and correct bus engineering as much as the transmitter electronics.

Apter Power can help confirm SICK ISD280-1112 interface, heated-operation requirement, transmission distance and connector scope before quotation.

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.
  • Bidirectional path: A matched pair exchanges serial traffic across the air gap.
  • Narrow alignment: Stable mechanical pointing keeps the remote unit inside the optical aperture.
  • Range planning: Distance, vibration and structure deflection are assessed together.
  • Line of sight: Loads, guards and moving equipment must not obstruct the beam.
  • Serial support: RS-422/485 equipment can use the contactless link.
  • PROFIBUS DP: The interface carries the established fieldbus when timing and termination are correct.
  • Low delay: Microsecond-scale transit limits the impact on industrial communication timing.
  • Connector boundary: D-sub and M12 connections separate data and supply functions.
  • Heated operation: Additional current powers the low-temperature heating function.
  • IP54 housing: The enclosure resists dust and splashing but still needs an appropriate installation.
  • Rigid mounting: Brackets must prevent vibration from moving the beam off target.
  • Clean optics: Dust or condensation on the window is managed through inspection and maintenance.
  • Stacker cranes: Transfers control data between the aisle structure and moving machine.
  • Overhead handling: Avoids a data cable across long crane travel.
  • Automated storage: Maintains communication to shuttles or transfer equipment with clear sight.
  • Moving platforms: Bridges a serial link where mechanical cable routing would restrict motion.
Description
ISD280-1112 sends bidirectional serial data over a modulated infrared beam across distances from 0.2 to 150 m. It carries RS-422/485 or PROFIBUS DP communication without a trailing cable between fixed and moving machine sections.

ISD280-1112 combines a narrow optical alignment window with microsecond-scale transmission delay. The heated version extends startup into low-temperature areas, making the unit useful on cranes, storage machines and transfer systems where mechanical cable travel would otherwise limit movement.

Technical notes
ISD280-1112 carries IP54 protection, which limits dust and splash ingress but does not make the optical face immune to obstruction or heavy contamination. A dirty window reduces usable link margin before the electronics indicate a hardware fault. Keep the beam window accessible for cleaning, and stop commissioning if guards or process deposits can block the line of sight.

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.
Does ISD280-1112 require one unit or a matched pair?
An optical communication path requires a unit at each end. Confirm that both units support the same interface, data rate, supply and environmental arrangement.
Why can ISD280-1112 lose communication only near the end of travel?
Longer distance and structural deflection can move the partner outside the narrow optical aperture. Check alignment at both travel extremes, not only at the service position.
Can ISD280-1112 carry PROFIBUS DP without changing the PLC program?
It can transport the physical communication link, but bus address, data rate, cable segments and termination must still satisfy the PROFIBUS design.
When is the heater function needed for ISD280-1112?
Use the documented heated supply allowance for low-temperature startup and operation. Confirm cabinet power capacity because heated current is higher than normal operation.
What should be recorded before replacing ISD280-1112?
Record both unit models, mounting angles, distance, interface, data rate, connector pinout, termination, supply, heater use and the travel positions where faults occur.
How should ISD280-1112 be commissioned on moving equipment?
Align the pair at both ends of travel, verify stable communication at full distance, then test motion, obstruction recovery and power cycling before releasing automatic operation.
