Installation guidelines

Mounting systems

Reduce mounting and adjustment time with ifm’s mounting systems. Customize each installation with only the components you need for an economical, adjustable, and high strength solution. Never lose reliability with a position or angle adjustment again.

Best practices

Avoid back light, scattered light and changing light conditions. The O2I5 can be setup with changing light conditions in mind, but it is always best to keep environmental conditions as stable as possible.
Install in front or above the object to avoid dust or dirt buildup on the face of the sensor.
If low-profile mounting is required to avoid physical impact, bounce the light source off a mirror and use the internal code mirroring correction for reliable detection.

Wiring and triggering

Image capture can be triggered with a binary device (like a photoelectric sensor) connected to the trigger input, a command from the process interface (EtherNet/IP or TCP/IP) or continuous capture with a fixed frame rate. The wiring schematic below shows triggering with a sensor.

PC for parameter setting
Industrial PC or PLC for evaluation and triggering

Power supply
Optional supplemental light source

For easy connection of trigger sensors and external light sources, ifm offers Y-splitters to provide power and internal connections to further simplify wiring. Please see EVC847 (for trigger sensors) and EVC848 (for external illumination).

Common trigger sensors

Triggers are used to confirm that the code is in place and initiate the image evaluation process. Any sensor can be used as a trigger so long as it physically fits in the application and provides repeatable indication of the code location. Below is our most common products. Triggering can also be done with a command from a PLC.

Supplemental lighting

While the integrated LED light source in the O2I code reader provides enough illumination for most applications, there are times when additional external light is required.
