الإعداد والتثبيت
Proper installation is crucial for optimal performance and longevity of the potentiometer.
التركيب
The 95A2A-B28-A10/A10L is designed for panel mounting.
- Ensure the mounting hole on the panel is appropriately sized for the potentiometer's bushing. Refer to the mechanical specifications for precise dimensions.
- Insert the potentiometer shaft through the panel hole.
- Secure the potentiometer using the provided nut and washer on the front side of the panel. Tighten firmly but do not overtighten to avoid damaging the component or panel.
التوصيلات الكهربائية
The potentiometer has three solder lug terminals.
- Terminal 1 (Counter-Clockwise End): Connect to one end of the circuit where resistance is desired.
- Terminal 2 (Wiper): Connect to the point where variable resistance is needed.
- Terminal 3 (Clockwise End): Connect to the other end of the circuit.
ملحوظة: For variable resistor (rheostat) applications, connect the wiper (Terminal 2) to either Terminal 1 or Terminal 3, and use the remaining two terminals.
Use appropriate soldering techniques to ensure secure and reliable electrical connections. Avoid excessive heat which can damage the internal components.
تعليمات التشغيل
The Bourns 95A2A-B28-A10/A10L is a single-turn potentiometer.
- تناوب: The shaft can be rotated approximately 270-300 degrees from one end stop to the other.
- تعديل المقاومة: Rotating the shaft changes the resistance between the wiper terminal and the end terminals.
- دوران عقارب الساعة: Typically increases resistance between Terminal 1 and Terminal 2, and decreases resistance between Terminal 2 and Terminal 3.
- Counter-Clockwise Rotation: Typically decreases resistance between Terminal 1 and Terminal 2, and increases resistance between Terminal 2 and Terminal 3.
Always ensure the circuit is de-energized before making or changing connections.
صيانة
The Bourns cermet potentiometer is a robust component designed for long-term reliability with minimal maintenance.
- تنظيف: If the external surfaces become dirty, gently wipe with a clean, dry, lint-free cloth. Avoid using solvents or abrasive cleaners.
- تقتيش: Periodically inspect the solder connections for any signs of corrosion or loosening. Ensure the mounting nut remains secure.
- الظروف البيئية: Operate and store the potentiometer within specified temperature and humidity ranges to prevent degradation.
Do not attempt to disassemble the potentiometer, as this will void any warranty and may damage the component.
استكشاف الأخطاء وإصلاحها
If you encounter issues with the potentiometer, consider the following common problems and solutions:
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| لا يوجد تغيير في المقاومة | Incorrect wiring; Open circuit; Damaged wiper. | Verify wiring connections; Check for continuity across terminals; Replace potentiometer if damaged. |
| Intermittent resistance | Loose connections; Contamination inside element; Worn element. | Resolder connections; Replace potentiometer. |
| Resistance value out of specification | Component tolerance; Environmental factors; Damaged element. | Verify against specifications; Ensure proper operating conditions; Replace if damaged. |
| Shaft difficult to turn | Overtightened mounting nut; Mechanical damage. | Loosen mounting nut slightly; Replace if mechanically damaged. |
