製品概要

この壁掛け式産業用制御シャーシは、PoEネットワークビデオレコーダー、産業用モーションコントローラ、エッジコンピューティング産業用PC、およびオートメーションマザーボードを収納するために専門的に設計されています。RS232/485シリアルポート、VGA、HDMI、USB、デュアルイーサネット、信号端子、アンテナインターフェース用の豊富な拡張ポートがあらかじめ確保されており、ほとんどの産業用制御、ビデオ監視、およびモーション制御マザーボードのレイアウト要件に完璧に適合します。

✅ 当社の主要な競争優位性（工場の長期的な強み）

フルカスタム板金加工ソリューション

お客様の図面やサンプルに基づき、全長、幅、奥行き、穴の位置、ポート数、取り付けブラケット構造など、あらゆる仕様をカスタマイズできます。高精度CNC曲げ加工とレーザー切断により、±0.1mmの公差で制御され、マザーボード組み立て後の二次加工は不要で、組み立て効率を大幅に向上させます。
事前予約済みのマルチインターフェースレイアウト、幅広い互換性

標準シャーシは、VGA、HDMI、シリアル通信ポート、ギガビットイーサネット、USB、ターミナル配線、RFアンテナポートのための十分なスペースを確保しています。PoE監視ホスト、モーションコントローラ、エッジゲートウェイ、産業用ゲートウェイ、および各種組み込み産業用コンピュータ機器の統合に適しています。
堅牢なSPCC鋼構造とプレミアム表面処理

厚みのあるSPCC冷間圧延鋼板構造を採用し、高い圧縮性と変形耐性を実現。筐体全体に静電防錆粉体塗装を施し、傷、埃、腐食に強く、過酷な工業用作業場、屋外キャビネット、機器室などの長期使用環境に対応します。スロット状の通気口を備え、内部の放熱効果を高め、マザーボードの過熱を防ぎます。
壁掛け設置設計、省スペース設置

側面固定式取り付けブラケットを備えているため、壁面への取り付けが容易で、キャビネットのスペースを節約できます。自動化生産ライン、セキュリティ監視エンジニアリング、インテリジェント交通、産業用エッジコンピューティング、現場制御盤などで幅広く使用されています。
工場直送供給＆安定した納期

中間業者によるマージンがなく、大量注文でも工場出荷価格で競争力のある価格をご提供します。小規模な試用注文から大規模なバッチプロジェクト注文まで対応し、生産前のサンプル確認、入荷および完成品の全工程における品質管理検査を実施することで、バッチの外観と寸法の均一性を保証します。シルクスクリーンロゴ、カラーカスタマイズ、表面仕上げのアップグレードなど、世界中の産業機器メーカーやシステムインテグレーター向けにワンストップのOEMおよびODMサービスを提供しています。
