Magnetic Switches & Sensors: Cylinder Position Sensing

To tell a PLC that a cylinder has reached the end of its stroke, you clamp one of these CS or ESMX reed switches onto the cylinder body and it trips off the piston's internal magnet. SPAC supplies them for T-groove cylinders (SDNC, ESNC, SDSU, EMAL, SDNU, SDVU, SX) and round-groove SQ2 bodies, with 2-wire and 3-wire PNP/NPN outputs plus the matching clamps. Automation engineers order them by groove type and output to feed position signals into a controller. 4 variants, from ₹205 + GST, with the final price confirmed on WhatsApp. Stocked in Sector 9, Noida and dispatched across Delhi NCR by Shri Narayan Machinery, an authorized SPAC dealer.
