MK11 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. Stainless Steel Plastic FEATURES • Stainless steel, plastic and brass 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 Brass MAGNETIC SENSITIVITY Sensitivity Class Pull In AT Range B 10 - 15 C 15 - 20 D 20 - 25 E 25 - 30 APPLICATIONS • Piston end travel and position detection • End motion detection for linear drives • Machine industry ORDER INFORMATION Part Number Example MK11 1A66 C - 500 W MK11/M8 - 1A66 C - 500 W MK11/B6 - 1A66 C - 500 W M8 is the thread B6 is the brass with M6 thread 66 is the switch model C is the magnetic sensitivity 500 is the cable length (mm) W is the termination Series Contactform Switchmodel Magnetic Sensitivity Cable Length (mm) Termination MK11 - 1A XX X XXX X 66 B, C, D, E 52, 85 C, D, E 1C 90** C, D, E 500* W 1A, 1B 1C, 1E MK11 (brass) B, C, D, E 1A Options * Other cable lengths available. ** Only for MK11/M8 (plastic). www.meder.com 242 MEDER electronic MK11 Series Reed Sensor with Screw Thread Enclosure DIMENSIONS All dimensions in mm [inch] MK11/M8 (Plastic) MK11 (Stainless Steel) 7.00 2 x plastics nut 25.00 [0.276] [0.984] Ø 4.50 [0.236] Ø 6.00 [0.236] Ø 6.00 [0.177] 3.00 [0.051] 38 [14.86] M8 ø 4.8 [1.89] SW 10 1.3 6 [0.512] [2.362] [1.969±0.394] 38 [14.86] 500 ± 10 [196.9±3.937] ø 10 [3.937] ends tinned SW 13 ends tinned M12x1 M10x1 ø 8 ends tinned Enden verzinnt MK11/B12 (Brass) MK11/B10 (Brass) 500 ± 10 [196.9±3.937] 500 ± 10 [196.9±3.937] 5 ±1 5 ±1 [1.969±0.394] 38 [14.86] ws 13 ø 6 [2.362] ends tinned Enden verzinnt M6 6 [2.362] 5.50 [0.217] Thread M8 x 1,25 MK11/B8 (Brass) MK11/B6 (Brass) 500 ± 10 [196.9±3.937] [0.236] 38.00 [1.496] fine thread M5 x 0.5 38 [14.86] 6.00 1.30 [0.118] 5 ±1 1.5 6 [2.362] [1.969±0.394] 5 ±1 SW 17 1.5 [0.591] 6 [1.969±0.394] SW 19 [2.362] TERMINATION For wire and termination details please consult factory.
