page 2 of 5 broader alignment tolerances, increased standoff clearance, smallest sensor and more why mercury encoders make it easier to design high performance into your equipment eliminate the frustration of touchy encoder alignment mercury solves this problem for good fussy alignment is no longer a concern. with mercury?s patented pureprecision ? optics, advanced smartprecision ? electronics and led alignment indicators, you can push the sensor against your reference surface, tighten the screws and you?re finished. try that with brand x or y. this performance is possible thanks to relaxed alignment tolerances, particularly in the theta z axis. mercury offers a 2 sweet spot? that?s a 300% improvement over the best competitive encoder. and that will result in dramatic savings in manufacturing costs. no other commercially available encoder is easier to align, easier to use, or easier to integrate into your designs. alignment tolerance comparison** mercury* brand x brand y mercury vs. best competito r z standoff 0.15mm 0.1mm 0.1mm mercury is 50% better y 0.20mm for linear 0.1mm unspecified mercury is 100% better 0.10mm for rotary 19mm dia. theta x 1.0 unspecified 1.0 theta y 2.0 0.1 1.0 mercury is 100% better theta z 2.0 0.006 0.5 mercury is 300% better *measured at a constant temperature for one axis at a time with all other axes at their ideal positions. **based on published specifications > _ mercury can reduce system size and cost mercury?s sensor height is 44% shorter than competitive encoders, making it easy to fit into your design. this reduction can also cut total system weight and cost by allowing the use of smaller motors and stages. safe system operation is also enhanced thanks to mercury?s generous standoff clearance? 200% greater than other encoders. and it?s standoff tolerance is 50% greater than the best alternative. this significantly relaxes mechanical system tolerances, while reducing system costs. b b r r a a n n d d y y b b r r a a n n d d x x m m e e r r c c u u r r y y 2 0.5 0.006 t t h h e e t t a a z z a a l l i i g g n n m m e e n n t t t t o o l l e e r r a a n n c c e e mechanical dimension comparison** mercury brand x brand y mercury vs. best competitor sensor z height 8.4mm 23mm 15mm 44% better standoff clearance 2.4mm 0.5mm 0.8mm 200% better standoff tolerance 0.15mm 0.1mm 0.1mm 50% better system height 11.7mm 28.5mm 15.8mm 26% better **based on published specifications note: mecury 1200 is even smaller at 5.6mm sensor height * dimensions shown illustrate encoder system standoff clearance; see mercury encoder interface drawings for correct design reference surfaces. b b r r a a n n d d x x b b r r a a n n d d y y m m e e r r c c u u r r y y s s t t a a n n d d o o f f f f c c l l e e a a r r a a n n c c e e 2.4mm* 0.15mm 0.8mm 0.1mm 0.5mm 0.1mm
