Présentation du produit

Ce châssis mural de contrôle industriel est conçu pour accueillir un enregistreur vidéo réseau PoE, un contrôleur de mouvement industriel, un PC industriel de périphérie et une carte mère d'automatisation. Il dispose de nombreux ports d'extension pré-réservés pour les ports série RS232/485, VGA, HDMI, USB, double Ethernet, les terminaux de signal et les interfaces d'antenne, répondant ainsi parfaitement aux exigences d'agencement de la plupart des cartes mères pour le contrôle industriel, la vidéosurveillance et le contrôle de mouvement.

✅ Nos principaux avantages concurrentiels (Atouts à long terme de l'usine)

  1. Solution complète d'usinage de tôlerie sur mesure

    Nous pouvons personnaliser entièrement la longueur, la largeur, la profondeur, la position des trous, le nombre de ports et la structure du support de montage selon vos plans ou échantillons. Le pliage CNC et la découpe laser de précision, contrôlés à ±0,1 mm près, ne nécessitent aucune modification secondaire après l'assemblage de la carte mère, ce qui améliore considérablement votre productivité.

  2. Disposition multi-interface pré-réservée, large compatibilité

    Le châssis standard offre un espace généreux pour les ports VGA, HDMI, de communication série, Gigabit Ethernet, USB, le câblage des terminaux et les ports d'antenne RF. Il convient à l'intégration d'un système de surveillance PoE, d'un contrôleur de mouvement, d'une passerelle périphérique, d'une passerelle industrielle et de divers équipements informatiques industriels embarqués.

  3. Structure robuste en acier SPCC et traitement de surface haut de gamme

    Adopter une structure en tôle d'acier SPCC laminée à froid et épaissie, offrant une résistance élevée à la compression et à la déformation. L'ensemble du boîtier bénéficie d'un traitement antirouille par pulvérisation électrostatique, le rendant résistant aux rayures, à la poussière et à la corrosion, et adapté aux environnements industriels difficiles, aux armoires extérieures et aux salles d'équipements. Des ouvertures de ventilation à fentes assurent une dissipation thermique interne efficace afin d'éviter la surchauffe de la carte mère.

  4. Conception pour installation murale, installation peu encombrante

    Doté de supports de montage latéraux fixes pour une installation murale facile, il permet de gagner de la place dans l'armoire et est largement utilisé dans les lignes de production automatisées, l'ingénierie de surveillance de la sécurité, les transports intelligents, l'informatique de périphérie industrielle et les armoires de contrôle sur site.

  5. Approvisionnement direct d'usine et capacité de livraison stable

    Pas de majoration d'intermédiaire, prix départ usine compétitifs pour les commandes en gros. Nous acceptons les petites commandes d'essai et les commandes de projets en grande série, avec confirmation complète des échantillons avant production et contrôle qualité à réception et sur produits finis pour garantir l'uniformité de l'aspect et des dimensions des lots. Nous proposons un service OEM/ODM complet incluant la sérigraphie de logo, la personnalisation des couleurs et l'amélioration des finitions de surface pour les fabricants d'équipements industriels et les intégrateurs de systèmes du monde entier.
