Hi-Tech Engineers manufactures proximity switches. These proximity switches are sensors available in three types, for various applications. The range comprises of: 1. Inductive proximity switches - these are used for sensing metals like MS, brass, copper, etc, and also useful for position sensing/speed sensing/object counting. These sensors give high speed reliable operations which are maintenance-free and provide a long-life service. They come in AC [2/3 wire], DC [2/3 wire PNP, NPN], Logic [NO/NC/CO] in M8 to M 48/block type/slot type sizes; 2. Capacitive proximity switches - These are used for sensing any dielectric material like glass, paper, water, oil, PVC, etc; useful for position-sensing/level-sensing/object-sensing /object-counting; sensors enable maintenance-free reliable operations at a very high speed; available in AC/DC version [2, 3 wire] PNP/NPN, Logic [NO/NC/CO] in sizes M18/M30/M50; and 3. Magnetic proximity switches - they function in presence of magnet, with operating distance up to 300 mm with potential free NO/NC contacts; available in AC and DC [2 and 3 wire]; these are useful for position, direction-sensing/speed measurement. Sizes of proximity switches are M8/rectangular and as per specifications.
