BL 3.50/16/180 SN OR BX PRT Weidmüller Interface GmbH & Co. KG Klingenbergstraße 26 D-32758 Detmold Germany www.weidmueller.com Accessories Cover hoods Effective protection, optimised ergonomics and closed design: From the strain relief on the connected conductors and the visual/contact protection and the disconnection aid: the optional retrofit hoods perform mechanical, visual and haptic functions. The two half shells clip together securely, enclose the plug completely and offer the following functions:

• Cable ties or integrated cable clips provide strain relief.
• Marked with dekafix labels or adhesive strips
• Mounting side by side without losing poles or displacing the pitch
• Compatible: suitable for plugs with or without a flange or mounting bracket
• Flexible: 1-3 cable outlets leading in different directions available depending on the size Weidmüller hoods offer added stability, better identification, complete compatibility and versatility. The result: maximum reliability and user-friendliness in any application.
