Always maintain air gap, angular and axial misalignment within specifications in order to prevent negative effects on the measuring accuracy. MDFK / MLFK Small misalignments within specifications result in minor system related measuring inaccuracies caused by ring magnets or magnetic strips (inaccuracy of magnetization, glued magnetic strip, true running of ring magnets). Ring magnets or magnetic strips should not be exposed to strong external magnetic fields, excessive ambient temperatures or heavy mechanical abuse like direct hits with hard objects. Also, be certain that ring magnets or magnetic strips are never placed near ferromagnetic parts, as this could cause magnetization resulting in signal distortion. angular misalignment air gap 0,4 - 0,8 mm (applies to applications with both ring magnets and magnetized strips) <3° axial misalignment <3° Mounting instructions <1 mm 192 <1° www.baumerelectric.com Accessories Magnetic sensors magnet rotor magnet rotor (zero pulse) mounting bracket MDFK 08 part nr. see chart part nr. see chart part number 8 26 D E D E øC reference Referenzmagnet magnet 4 9,5 8 3,5 2,1 H mounting MDFK 08 (0-pulse) 32 poles 36 poles 64 poles 40 40 66 36 poles 64 poles 30,5 30,5 56 A 20 20 66 6H7 6H7 25E7 B 20 20 35 B C 6H7 6H7 25E7 C D 14 14 15 D 17 17 18 E 7/5 7/5 8/6 E 8/5 8/5 9/9 F M3 M3 M4 F M3 M3 M4 G – – – G 30,5 30,5 56 18 18 31,3 H – – – H material alu alu alu material alu alu alu part number 134061 157948 143924 part number 132124 147433 150984 ring magnet 32 poles part number 156640 ring magnet 36 poles part number 147431 mounting Montagebracket winkel 134683 134683 Referenzreference magnet magnet Magnetrotor rotor Accessories dimension with zero pulse 32 poles A 2,5 0,4 - 0,8 mm dimension without zero pulse 1 ø4,1 16 3 øG M2,5 x 5/8 11 øC 15 F 15 F øA øB 134683 øA øB ring magnet 64 poles part number 143920 30,5 ø30,6 ø22 8±0,1 30,5 ø30,6 ø22 6,8 6,8 ø56 ø47,8 Magnetic sensors Ring magnet can be designed to meet application specific requirements. www.baumerelectric.com 193 Accessories Magnetic sensors magnetic strip for MLFK magnetic strip for MLFK self-adhesive protective tape length 50 mm 150 mm 300 mm L= (cut to length) length L= (cut to length) part number part number 147044 157164 10 for MLFK with suffix X only 10 10 part number 128662 128663 128664 128606 L=...m L=...m pole width 2 mm strip thickness 1,4 mm L=...m pole width 1 mm strip thickness 1,4 mm strip thickness 0,25 mm rotor M3 5 22 123344 15 part number ø 6 H7 ø 16 connector part number ESW 33AH0200 ESW 33AH0500 ESW 33AH1000 halogen-free 4-pin 4-pin 4-pin ESW 33A connector cable length 2 m PUR 5 m PUR 10 m PUR part number ESG 34AH0200 ESG 34AH0500 ESG 34AH1000 halogen-free 32 L 4-pin 4-pin 4-pin M12 x 1 26,5 Magnetic sensors part number ESW 31AH0200 ESW 31AH0500 ESW 31AH1000 halogen-free 4-pin 4-pin 4-pin ESW 31A connector cable length 2 m PUR 5 m PUR 10 m PUR part number ESG 32AH0200 ESG 32AH0500 ESG 32AH1000 halogen-free M8 x1 ø 10 16,5 26 L 30 color BN (brown) WH (white) BU (blue) BK (black) signals +Vs NC (output B) 0V NO (output A) pin-assignment con. 4-pin (M8) 4 cable length 2 m PUR 5 m PUR 10 m PUR see color code for wiring M8 x1 194 4-pin 4-pin 4-pin 3 L ESG 32A see color code for wiring ø 10 1 2 4 pin nr. 1 2 3 4 42 connector pin-assignment con. 4-pin (M12) cable length 2 m PUR 5 m PUR 10 m PUR ø 14,7 ø 14,7 ESG 34A M12 x 1 Accessories magnet magnet 6 x 3 x61x 3 x 1 L www.baumerelectric.com 3 pin nr. 1 2 3 4 color BN (brown) WH (white) BU (blue) BK (black) 2 1 signals +Vs NC (output B) 0V NO (output A)
