Balluff Expands BES Entry Line With More Sensor Options

Balluff has expanded its BES Entry Line of inductive sensors with new cable and NPN configurations, giving machine builders more flexibility for standard automation applications. The portfolio now spans M8, M12, and M18 sizes with connector, cable, and pigtail options, while 360-degree LED indicators simplify status checks and troubleshooting. Designed with straightforward installation and high-volume applications in mind, the lineup provides a cost-effective sensing option for manufacturing, assembly, intralogistics, and material-handling systems.

Expanded Connection and Output Options

The updated BES Entry Line now comes in connector, cable, and pigtail versions, with both PNP and NPN normally open outputs. Connector models are available in M8, M12, and M18 sizes, while the cable version uses a 2-meter open-wire TPU cable. These new options make it easier for users to choose sensors that fit different connection needs or output types. The cable models provide open-wire connections, and the NPN versions are suitable for control systems that require them. There is also a pigtail version with a 0.8-meter TPU pigtail and an M12 male three-pin connector.

Switching frequencies for these sensors range from 300 Hz to 600 Hz, depending on the model. The IP67-rated connector versions run on 10 to 30 V DC. All sensors have nickel-plated die-cast zinc housings with PBT sensing surfaces and are made for flush mounting.

360-Degree Status Indication

A useful feature of the BES Entry Line is its 360-degree LED indicator. After installation, the back of the sensor lights up to show its status. Balluff says the display shows switching status, power supply status, and fault conditions such as short circuits. This makes it easier to spot problems and quickly identify sensor or wiring issues. When many sensors are installed close together, the visible indicator helps technicians find the one that needs attention.

The Entry Line can be used with an optional clamp holder that has a fixed stop. This mounting method is designed to make installation and replacement easier and to require no tools.

Packaging for Higher-Volume Applications

This sensor line is meant for situations where many sensors are needed. Balluff says the connector models can be shipped in multi-piece packs, which reduces packaging and uses 96% less plastic than before. This not only reduces waste for large orders but also makes unpacking easier for high-volume users.

As an entry-level option for standard factory automation, the BES Entry Line is suitable for electronics manufacturing, mechanical engineering, intralogistics, assembly and handling, and textile processing. These fields often require many sensors that are easy to install and maintain.

Broader Choice for Machine Builders

With the expanded BES Entry Line, Balluff now offers more connection and switching options in its standard inductive sensor range. The mix of M8, M12, and M18 sizes, PNP and NPN outputs, and connector, cable, and pigtail choices gives machine builders more flexibility to match sensors to their machines. This makes the line a good fit for standard factory automation and a variety of installation needs.
