Key Wiring Requirements

1. Twisted shielded cable is mandatory; shield layer grounded at both ends (control cabinet & encoder connector)
2. Differential signal pairs A/A-, B/B-, Z/Zshall be twisted separately to reduce interference
3. For long cables (>10م), 120Ω terminal matching resistor is recommended
4. Signal Output Waveform Description
5. Phase A and B are 90° quadrature; Phase A leads Phase B under clockwise rotation
6. One Z pulse per revolution, with window width equal to a 90° A/B cycle
7. Complementary differential output effectively suppresses EMI interference from motors and inverters
8. Push-pull output can be directly connected to HTL differential input ports of PLCs and servo drives
9. معايير التثبيت & Torque Requirements

6.1 Shaft Mounting Requirements

1. Coaxiality error of driving shaft ≤0.2mm, radial runout ≤0.03mm
2. After fitting hollow shaft onto driving shaft, tighten set screw at torque of 1.2 ن · م. Do not over-tighten to avoid shaft deformation
3. A torque stop arm must be installed at encoder tail to prevent housing rotation with the shaft; leave tiny floating clearance on stop arm to avoid rigid jamming

6.2 Prohibited Operations

Do not strike encoder housing or shaft bore

Do not apply heavy axial extrusion to blind hollow shaft

Do not fix housing directly without torque stop arm

Do not operate without sealing kit under dusty or splashing water environments

7. البيئية & Certification Standards
8. لا توجد شهادة مقاومة للانفجار; not applicable for flammable and explosive hazardous areas
9. حماية IP65: resistant to splashing water and dust, not for long-term immersion
10. اهتزاز & shock resistance meets heavy-duty working conditions of cranes, آلات الميناء, machine tools and paper mills
11. UL certification supports equipment export to North America
12. مصفوفة استكشاف الأخطاء وإصلاحها المشتركة

Compatibility Comparison Table

مزايا الاستبدال

Sufficient stock with no risk of supply shortage due to discontinuation

1:1 mechanical & electrical compatibility, no cabinet modification or program adjustment needed

Superior temperature range and shock resistance compared to legacy BHT series

10. تحذيرات السلامة
11. Cut off main power supply before wiring, disassembly or assembly to prevent short-circuit burnout of encoder
12. Shielded cables must be used near inverters and high-power motors to avoid counting interference
13. Waterproof M23 connectors are required for long-term outdoor operation to prevent moisture ingress into connector
14. Continuous operation over 6000rpm will permanently damage the optical grating disc
15. Do not disassemble encoder housing without authorization; disassembly invalidates sealing and warranty
