最近、KaconのK16シリーズスイッチの端子数について、お問い合わせをいただきました。例えば K16-291-G-24VDC（ 2371-K16-291-G-24VDC-ND ）を例に挙げると、当社製品ページでは端子仕様として「はんだ付け、クイックコネクト - 0.110インチ（2.8mm）」と記載されていますが、端子の数については明記されておらず、データシートにも記載されていません。回答は、お客様の具体的なスイッチモデルによって異なります。
この情報を見つけるには、メーカーのウェブサイトにあるカタログを調べる必要があります。
必要な端子数を決定するには、コンタクトの形式とスイッチが照光式であるかどうかの2つの情報が必要です。
上記の品番例、K16-291-G-24VDC についてご説明しましょう。カタログの2ページに記載された品番の構成から、当部品はコンタクト形式が1Cであり、照光式であることが確認できます（下記参照）。
その情報を確認後、16ページの配線図に進むと、スイッチには5つの端子があることがわかります（下記参照）。
以下は照光式1Cの配線図を拡大表示したものです。
