Housing for industrial connectors


Connector housing

Connector housing overview

HEAVYCON connector housing Complete flexibility

You can always create the right connection for your requirements with connector housings from our three series types and matching contact inserts. All housing series fit on standard panel cutouts. STANDARD and EVO housings require a panel mounting base for the panel feed-through. ADVANCE housings can be mounted directly onto the wall using the panel mounting flange. The sleeve housings, panel mounting bases, surface mounting housings, and coupling housings can be freely combined with one another within the STANDARD and EVO series. They are mounting and plug-in compatible with aluminum housings from well-known manufacturers. This allows all components to be individually combined and flexibly modified, extended, or exchanged.

HEAVYCON ADVANCE Robust without compromise

HEAVYCON ADVANCE heavy-duty connectors with screw locking mechanism are ideally suited for particularly aggressive surroundings, for example, in offshore areas, or the chemical or railway industry. Sensitive interfaces are reliably protected, even against electromagnetic interference. For the panel feed-through, the panel-mount base that is normally used has been replaced by two simple panel-mount flanges, thereby reducing mounting and material costs. With this method, the sleeve housing forms a seal directly on the control cabinet panel.

HEAVYCON ADVANCE industrial connectors without panel-mount base

HEAVYCON ADVANCE eliminates the need for the panel-mount base that is normally used on the device side. The housings are therefore particularly durable, robust, and space-saving.

HEAVYCON ADVANCE savings potential

Without the need for the normal panel mounting base, you save on mounting and material costs. The low designs of the metal and molded cable glands of the plastic housings offer further savings potential.

HEAVYCON ADVANCE screw locking mechanism

Mount the ADVANCE sleeve housing with two panel mounting flanges and robust stainless steel locking screws directly onto the wall. This achieves a high degree of tightness and makes it more difficult for unauthorized persons to gain access.

HEAVYCON ADVANCE housing versions

HEAVYCON ADVANCE is available in metal or plastic. The powder-coated outdoor housings are suitable for extreme demands.

Configure HEAVYCON ADVANCE industrial connectors

Combine the ADVANCE housing with modular or fixed-position contact inserts, according to your requirements.
