3.1 Коопсуздук чаралары
- Ensure all power is disconnected before installation or wiring.
- Коргоочу көз айнек сыяктуу тиешелүү жеке коргонуу шаймандарын (ЖКК) кийиңиз.
- Handle with care to avoid damaging the terminals or the internal mechanism.
3.2 Монтаждоо боюнча нускамалар
- Prepare a suitable panel opening for the potentiometer's threaded shaft (6.35mm diameter).
- Insert the potentiometer shaft through the panel opening.
- Secure the potentiometer to the panel using the provided nut and washer. Tighten firmly but do not overtighten.
3.3 Электр байланыштары
The potentiometer features solder lugs for electrical connections. Refer to your circuit diagram for specific wiring. A typical connection involves:
- Terminal 1 (End Terminal): Connect to one end of the voltage source or signal.
- Terminal 2 (Wiper Terminal): Connect to the output or variable resistance point.
- Terminal 3 (End Terminal): Connect to the other end of the voltage source or ground.
Ensure clean, secure solder joints to prevent intermittent connections or resistance fluctuations.
4. Иштөө нускамалары
The BOURNS 3852A-162-501A is a single-turn potentiometer, meaning its full resistance range is covered within one complete rotation of the shaft.
- Жөнгө салуу: Rotate the shaft clockwise or counter-clockwise to adjust the resistance value.
- Каршылык диапазону: The resistance will vary from approximately 0 Ohms to 500 Ohms as the shaft is rotated from one extreme to the other.
- Мониторинг: Use a multimeter or appropriate measurement device to verify the desired resistance or voltage output during adjustment.
Эскертүү: Avoid forcing the shaft beyond its mechanical stops, as this can cause internal damage to the potentiometer.
5. Техникалык тейлөө
The BOURNS 3852A-162-501A Cermet Potentiometer is designed for long-term reliability with minimal maintenance. However, adhering to these guidelines can extend its lifespan:
- Тазалоо: Keep the potentiometer free from dust, dirt, and moisture. Use a soft, dry cloth for external cleaning. Avoid using solvents or abrasive cleaners.
- Экологиялык шарттар: Operate and store the potentiometer within its specified temperature and humidity ranges to prevent degradation.
- Текшерүү: Periodically inspect solder connections for integrity and ensure the mounting nut remains secure.
