Product Introduction
The Bently Nevada 3500/25 128075-01E Slot Cover is a critical accessory designed for use within the Bently Nevada 3500 Series Machinery Protection System. Though seemingly simple in function, the slot cover plays an essential role in maintaining proper airflow, safety, EMC shielding, and dust protection within the 3500 rack system.
When a monitoring slot is not populated with an active module, this 128075-01E slot cover is installed to close the gap, preventing exposure to internal components and ensuring the rack complies with environmental protection and cooling requirements. It’s particularly important in industrial applications where vibration, dust, humidity, and electrical noise are present.
Constructed with durable, lightweight material and built to exacting Bently Nevada rack standards, the 3500/25 128075-01E ensures system integrity and longevity, even in harsh environments.
