How the BMD-6206-064S2-UA108A model number is decoded

Dimensionally the unit is 30/62/16 mm: the embedded deep groove ball bearing carries the load path and the sensor ring shares that same bore envelope; basic ratings are C 19.5 kN dynamic and C0 11.2 kN static, with a fatigue load limit of Pu 0.475 kN. Rated 64 pulses per revolution at a period accuracy of ±4%, the unit outputs two 90°-shifted signals held within ±30°; the mechanical limiting speed is 7500 r/min. A 1.741 static-to-dynamic load ratio confirms this is a genuine bearing unit rather than a bearing with a separate magnetic ring: C0 11.2 kN and C 19.5 kN are the standard ratings for this ISO 15 envelope. 240 g on a 30x62x16 mm envelope, fitted with a 565 mm lead and a AMP Superseal connector. Across the 64-pulse size the plug type is the only electrical difference. Running to its 7500 r/min limit the 64-pulse channel emits 8000 Hz, one pulse per 5.625° of shaft turn — confirm the controller's maximum input frequency is not exceeded. at 30 mm bore this size balances load capacity against the compactness needed at the rotor end of a motor shaft reading the BMD stack left to right: the embedded bearing code fixes the ISO 15 boundary dimensions, /064S2 fixes the output as two 64-pulse signals, and the U + cage + connector tail describes region, cage material and plug. The 108A tail is the AMP Superseal connector option — a sealed automotive-grade plug chosen where the wiring harness needs a keyed, water-resistant interface, and its lead runs 5 mm longer than the free-end alternative. The U/A block is a stamped steel ball cage, the standard choice at sizes whose load ratings are too high for a polymer cage. typical applications include machine-tool spindle position monitoring, industrial automation axis control and conveyor pulley speed and direction sensing this unit is commonly specified for machine-tool spindle position monitoring and industrial automation axis control, where rotor position and speed sensing with a 64-pulse signal fits the controller's input in conveyor pulley speed and direction sensing the integrated bearing carries the shaft load while the sensor ring supplies the signal; the 240 g mass keeps the rotating inertia low the sensor ring and the ball raceway share one compact unit — a bearing that is due for replacement takes the encoder signal with it, so renew both together the patterned sensor track is sensitive to contamination; a recessed or poorly sealed mounting face lets debris interrupt individual pulses the cable tail is part of the unit and cannot be shortened freely — terminating it outside the specified connector changes the screening and can corrupt the signal

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the sensor ring and the ball raceway share one compact unit — a bearing that is due for replacement takes the encoder signal with it, so renew both together
• the patterned sensor track is sensitive to contamination; a recessed or poorly sealed mounting face lets debris interrupt individual pulses
• the cable tail is part of the unit and cannot be shortened freely — terminating it outside the specified connector changes the screening and can corrupt the signal
