1. アプリケーションシナリオ
2. 産業用制御

– Widely used in start-stop control and mode switching (such as manual/automatic conversion) of mechanical equipment, 例えば, the operation panels of machine tools and production line conveyors.

– Can replace the traditional LA18 series push buttons and is compatible with the installation dimensions of international brands such as Schneider XB2.

2. Signal Indication and Safety Control

– If the optional illuminated model (例えば, NP2-BW3361) is selected, it can integrate an LED indicator light (AC/DC 6-220V) for status display (such as power indication, operation/stop feedback).

– Often used in conjunction with emergency stop buttons (例えば, NP2-BS542) and contactors to form a complete safety control circuit.

Ⅲ. インストールと使用方法

1. インストール手順

Panel Drilling: Use a Φ22.3mm drill bit to drill a hole, ensuring the panel thickness meets the requirements (1-6mm for metal head, 1-4mm for plastic head).

固定方法: The metal head type needs to be inserted from the front of the panel, and the base should be tightened from the rear; the plastic head type requires removing the base first, then assembling it after installation.

配線例: を接続します。 2 normally open contacts to the control wires L1/L2 respectively, and connect the common terminal to the power supply or load. For details, refer to the general wiring diagram of the NP2 series.

2. 予防

– Avoid using it in an environment with humidity >90%, 温度 < -5℃ or >40℃ to prevent contact oxidation or aging of plastic parts.

– 配線前に電源を切ってください, ensure the terminals are not loose, and avoid short-circuit risks.

1. 認証とコンプライアンス
2. 国内認証

GB/Tに準拠 14048.5 standard and has passed the CCC certification, suitable for domestic industrial scenarios.

2. 国際認証

Some models have passed CE and UL certifications (例えば, NP2-BD25), which can meet the access requirements of the European Union and North American markets.

3. 品質保証

CHINT provides a 1-year warranty. 確実に正規品をご購入いただくために正規代理店からのご購入をお勧めいたします (such as Lichuang Mall, Taobao Official Store).

1. 価格と購入方法
2. 市場価格

– The unit price of the basic model (2いいえ, 非照明) およそです 2.07-8.55 人民元, and the price of the illuminated model (例えば, NP2-BW3361) およそです 15-25 人民元, depending on the channel and batch.

– まとめ買いの場合 (より多い 100 個), you can negotiate the price through the CHINT official website or distributors, 単価を下げることができます 5-7 人民元 (WhatsApp経由で連絡する: 0086-13811255435 交渉のため).

1. 競合他社との比較
2. Comparison with NP2-BD25

Functional Difference: BD25 is a 2-position switch with 1 通常開 + 1 通常閉 (1NO+1NC) 連絡先, while BD23 is a 2-position switch with 2 通常開 (2いいえ) 連絡先. The selection should be based on circuit requirements.

価格差: The unit price of BD25 is about 10%-15% より高い, but it provides more flexibility in contact combination.

2. Comparison with Schneider XB2-BD21

互換性: The installation dimensions are completely the same, 直接交換できます, but the price of NP2-BD23 is 30%-50% より低い.

Performance Difference: The protection class IP65 is standard for XB2-BD21, while NP2 requires additional customization. It is recommended to prioritize XB2 for outdoor scenarios.

Ⅶ. よくある質問 (FAQs)

1. Q: Does the NP2-BD23 support 3-position operation?

– あ: The BD23 has a 2-position locking design. For the 3-position function, the NP2-BD33 (3-position locking, 2いいえ) 選択されるべきです.

2. Q: Can it be used in a 24V DC circuit?

– あ: It supports DC 24V. It is necessary to ensure that the contact capacity matches (0.6DC-13負荷時). It is recommended to select the illuminated model (例えば, NP2-BW3361 24V) to simplify wiring.

3. Q: 製品の真正性を確認する方法?

– あ: The packaging of genuine products is equipped with an anti-counterfeiting label, which can be verified by entering the verification code through the “Anti-counterfeiting Query” on the CHINT official website; the base of the metal head product is engraved with the “きちんとした” laser logo.

VIII. 選択の推奨事項

Economical Needs: Choose the basic NP2-BD23 model (2いいえ, 非照明), which is suitable for pure control scenarios, 単価は約 2.07-5 人民元.

Multi-functional Needs: Match with illuminated modules (例えば, NP2-BW3361) and contact expansion boxes (例えば, NP2-B02 dual-hole empty box) to realize status indication and multi-circuit control.

High Protection Scenarios: Customize the IP65 version (model suffix with “C”), which is suitable for environments such as dusty workshops and outdoor equipment.
