MK11 + MK 11/M8 Series MEDER electronic Reed Sensor with Screw Thread Enclosure DESCRIPTION MK11 sensors are magnetically operated Reed Sensors with screw thread enclosure supplied with interconnect cable. The sensor should be mounted on a fixed surface with the actuating magnet on the moving surface. Introduction or removal of the magnetic field determines the closing and opening of the Reed Switch. APPLICATIONS • Piston end travel and position detection • End motion detection for linear drives • Machine industry FEATURES • Stainless steel and plastics designs with thread for space adjustment • High power switches available • Other cables, connectors and colors available • Various case sizes available • Five operate sensitivities available • A choice of cable terminations and lengths are available DIMENSIONS All dimensions in mm [inches] MK11 (Stainless Steel) 7.00 [0.276] MK11/M8 (Plastics) 2 x plastics nut 25.00 [0.984] Ø 4.50 3.00 [0.118] 6.00 1.30 [0.051] [0.236] 38.00 [1.496] fine thread M5 x 0.5 www.meder.com 226 [0.236] Ø 6.00 [0.236] Ø 6.00 [0.177] 5.50 [0.217] Thread M8 x 1,25 ws 13 MK11 + MK11/M8 Series MEDER electronic Reed Sensor with Screw Thread Enclosure ORDER INFORMATION Part Number Example MK11 - 1A66 MK11/M8 - 1A66 C - 500 C - 500 66 is the switch model C is the magnetic sensitivity 500 is the cable length (mm) W is the termination W W Series Contactform Switchmodel Magnetic Sensitivity Cable Length (mm) Termination MK11 - 1A XX X XXX X 66 B, C, D, E 84** B, C, D, E 500* W 90** C, D, E 1A Options 1C * Other cable lengths available. ** Only for MK11/M8 (plastics).
