Omron Nb Series
Sear Sommerfeldt
The D4A limit switch series offer increased sealing protection, shock resistance and strength. It provides excellent durability with a wide operating temperature of -40C/F- 100C/212F (standard type). Utilizes a 29.4mm x 59.5mm mounting hole pattern.

The CP1W-CIF41 Ethernet Option Board is vulnerable to a Web UI password that can be read from memory using the Omron FINS protocol. An attacker obtaining this password could change the network settings of the option board.
The logic that is downloaded to the PLC is not cryptographically authenticated, allowing an attacker to manipulate transmitted object code to an unprotected PLC without using the PLC protection password. An attacker could then execute arbitrary object code commands on the defined software logic for all versions of SYSMAC CS/CJ/CP series controllers and cause a denial-of-service condition.
The logic that is downloaded to the PLC is not cryptographically authenticated, allowing an attacker to manipulate transmitted object code to the PLC and execute arbitrary machine code on the processor of the PLC's CPU module for SYSMAC NJ/NX series controllers.
For CVE-2022-31207: Omron recommends users of SYSMAC CS/CJ/CP Series to use the PLC protection password and enable protection against unauthorized write access to address. Also, there are hardware DIP switches on the PLC which can prevent unauthorized PLC program changes regardless of password.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
The long, 20-m maximum sensing distance of the MS4800 Series marks the highest level in the industry. Even in applications where large, complicated machines are guarded, the use of mirrors can reduce the number of Safety Light Curtains required.
Up to four systems can be connected in series (for a total of 256 beams) without having to connect a controller. Models for which the smallest detectable object is different can even be connected to respond flexibly to virtually any application.
Complete with an LCD that displays in either English or Japanese, the PDM makes it easy and intuitive to program, change settings, and troubleshoot the MS4800 Series.
- Easy operation with five function buttons.
- Allows setting changes and status monitoring.
- IP65 protection.
- Safety outputs operate while the PDM is connected, making it possible to monitor during operation.
The MS4800-series Receiver is equipped with OMRON STI's unique Individual Beam Indicator (IBI) function. When a beam is interrupted, or when it is out of alignment, an individual LED lights at each corresponding Receiver beam position to notify the operator. This makes it easy to align beams even from a distance. An error code is also displayed when an error is occurs. (This function is provided only on the Receiver.)
When a machine or a workpiece is present inside the sensing area of the Safety Light Curtain, the output turns OFF and the machine cannot be started. However, a blanking function can be used to disable the appropriate beams of the Safety Light Curtain and allow work to continue without stopping the machine. The MS4800 Series provides four blanking functions to combine both safety and productivity in a wide range of applications.
This function is used when a machine or workpiece constantly interrupts beams in a part of the sensing area. Fixed Blanking allows the Safety Light Curtain to remain in the RUN state while the obstruction is fixed (as a non-moving object) within the sensing area. The output is turned OFF when a beam other than the set fixed blanking beams is interrupted, or when light is incident on a fixed blanking beam.
This function is used when a machine or workpiece constantly interrupts beams in a part of the sensing area and moves within the sensing area. Monitored Blanking allows the Safety Light Curtain to remain in the RUN state while the obstruction moves within the sensing area. The output is turned OFF when the machine or workpiece disappears from the monitored blanking area that was set by teaching, or when the total number of interrupted beams increases due to a different obstruction.
When the resolution of the MS/MSF4800A is reduced, the size of the smallest detectable object is increased. The output will not turn OFF regardless of how many continuous interrupted beams there are in the sensing area as long as the beams are fewer than the set number (1, 2, or 3 beams). When an object whose size exceeds the set number of beams intrudes, the output is turned OFF. For example, in an application where a conveyor cart approaches a robot work area, the Safety Light Curtain can be set so that it does not detect only the wheels of the cart, allowing the MS/MSF4800A to be used as a presence sensing device.
In applications where it is necessary for an object to regularly pass through the sensing area, for example to supply workpieces to a machine, the output will turn OFF each time the object passes through, thus lowering productivity. The muting function makes it possible to raise productivity in this kind of application by temporarily disabling the Safety Light Curtain.
Select from among four muting modes to match each application with the appropriate number and placement of muting sensors.
Is it possible to migrate the program from a NT or NS, to a NB ?? I've read you have to design all the project again. It'd take value time just to copy the same project. I think it should, because it's the same brand of Operator Panel, Omron.
Omron's solution is to convert to an NS series HMI. I've done this conversion (NT to NS) several times and it is very good compared to most manufacturers. The NB is a low cost HMI. As with most manufacturers, you get what you pay for.
