E7191-090-008 by Okuma

The E7191-090-008 mountable rack by Okuma is a core component of the E7 Mountable Racks series engineered for industrial automation environments. This precision-machined chassis is fabricated from Material: Stainless Steel with a Finish: Polished surface, delivering both aesthetic quality and robust durability. It measures Length: 90 mm and features a Diameter: 8 mm profile, conforming to an exacting Tolerance: ±0.05 mm standard. The integrated Thread Type: M8 interface simplifies secure attachment within cabinet enclosures, while the overall Weight: 0.18 kg minimizes added load on support structures. Compliance with Standard Compliance: ISO 898-1 and Corrosion Resistance: High ratings ensures long-term performance in harsh operating conditions.

The internal architecture centers on a reinforced industrial grade sheet metal frame and a proprietary synchronous backplane bus for controller card integration. Ten vertically aligned slots utilize DIN 41612 connectors with gold plating to guarantee signal integrity, and four auxiliary positions accommodate logic or power boards. Active cooling is provided by an Axial fan cooling solution complemented by a rear vented grill, maintaining component temperatures across the specified Temperature Range: -20°C to 200°C for uninterrupted operation. Blue DB15 connectors labeled XB-FRP1 through XB-FRP4 enable diverse data paths, supporting serial (RS-232/422) and parallel I/O channels. All connections are secured with thumb screws to prevent vibration-induced disconnections in demanding industrial settings.

Reliability is further enhanced by the rack’s mechanical hardness of Hardness: HRC 30-35, ensuring resistance to wear and deformation under repeated card insertions. The standardized slot spacing and connector formats deliver consistent alignment and ease of integration with Okuma CNC controllers and third-party modules. Its polished stainless steel construction and M8 mounting thread afford both corrosion-resistant protection and straightforward installation within DIN-based enclosures. The rack’s design flexibility makes it ideally suited for factory automation, CNC machining centers, and PLC-based control panels where compact, high-performance backplane solutions are required. With built-in support for Okuma protocols and legacy interfaces, the E7191-090-008 offers a future-proof foundation for scalable machine control applications.
