PR12-2DN2光電開關(guān)是由韓國品牌奧托尼克斯（Autonics）生產(chǎn)的一款接近開關(guān)。奧托尼克斯成立于1977年，是一家專業(yè)生產(chǎn)電子電機相關(guān)產(chǎn)品的企業(yè)。PR12-2DN2采用直流三線式設(shè)計，工作電壓為12-24VDC，檢測距離為2mm。其外殼采用黃銅材質(zhì)，表面鍍鎳，具有良好的耐腐蝕性。該產(chǎn)品采用屏蔽型設(shè)計，可有效防止電磁干擾，確保檢測的準確性。此外，PR12-2DN2還具備內(nèi)置浪涌保護電路和過電流保護功能，能夠有效延長使用壽命。在價格方面，PR12-2DN2在不同采購數(shù)量下價格有所不同，例如在e絡盟中國，單件價格為233.92元，采購數(shù)量越多，單價越低。

The PR12-2DN2 photoelectric switch is produced by Autonics, a South Korean brand established in 1977. It is a type of proximity switch designed with a DC 3-wire configuration and operates within a voltage range of 12-24VDC. The detection distance of this switch is 2mm. The housing of the PR12-2DN2 is made of brass and is nickel-plated, providing excellent corrosion resistance. This switch features a shielded design, which effectively prevents electromagnetic interference and ensures accurate detection. Additionally, the PR12-2DN2 is equipped with built-in surge protection circuits and overcurrent protection functions, which help to extend its service life. In terms of pricing, the cost of the PR12-2DN2 varies depending on the quantity purchased. For example, on element14, the price per unit is 233.92 yuan for a single piece, with the unit price decreasing as the quantity increases.
