The Bently Nevada 128987-130-02-05 is a 3300 XL Proximitor® Sensor incorporating a number of improvements over previous Proximitor® Sensor designs. These improvements focus on mounting flexibility, electrical isolation, installation density, and enhanced resistance to radio-frequency and electromagnetic interference.

The physical packaging of the 3300 XL Proximitor® Sensor allows it to be used in high-density DIN-rail installations. This configuration provides a practical mounting arrangement where multiple sensors need to be installed within a limited panel or cabinet space.

In addition to DIN-rail mounting, the 128987-130-02-05 can also be installed using a traditional panel-mount configuration. For this type of installation, the sensor maintains an identical four-hole mounting footprint to older Proximitor® Sensor designs, supporting installation where the previous mounting arrangement is already present.

Frequently Asked Questions

Q : What is the exact product name of the part number 128987-130-02-05?

A: It is an Extension Cable for the Bently Nevada 3300 XL 8mm Proximity Transducer System.

Q : What does the option "-130" stand for in the part number?

A: It indicates the total length of the extension cable. In Bently Nevada’s naming convention, "-130" represents a length of 13.0 meters.

Q : What is the minimum bend radius required when installing this armored cable?

A: For armored cables, the minimum bend radius is generally 30 mm (1.2 inches). Bending it too sharply will damage the internal coaxial structure.

Q : Is this specific part number (128987-130-02-05) obsolete?

A: No. As part of the core 3300 XL 8mm ecosystem, this series remains active and is the global standard for industrial machinery monitoring.

Product Applications
