Functional Description
SC628AN is a Piezoelectric Transducer developed by Mallory Sonalert. This transducer generates a high-intensity sound signal, making it suitable for environments where auditory signals need to be heard over significant distances or in noisy conditions. Its broad voltage range, high output loudness, and rugged construction make it a versatile choice for a wide variety of industries, from manufacturing and emergency systems to consumer products. Whether you need to alert personnel to safety hazards or deliver clear, continuous sound signals.
Features
- Sound Level:It has a loud sound level category, with a typical output loudness of 88 to 101 dB(A) at 2 feet. The minimum loudness at the lowest voltage (7.5V DC) is 80 dB(A), and the maximum loudness at 28V DC can reach 95 dB(A), making it ideal for noisy environments that demand high visibility in terms of sound.
- Mode of Operation: The transducer operates in continuous mode, meaning it produces a constant sound rather than intermittent tones. This is advantageous in environments where continuous alerting is necessary, such as in industrial alarms or emergency systems.
- Frequency Range: The resonant frequency of the transducer is 2.9 kHz, with a tolerance of ±500 Hz. This frequency is within the range typically used for alarm sounds, ensuring the sound is attention-grabbing and easily detectable.
- Current Draw: The current draw of the SC628AN ranges from 4 to 30 mA, depending on the voltage supplied and the operating conditions, making it energy efficient for a wide variety of applications.
- Voltage Rating: Operate on a voltage range of 6 to 28 VAC/DC, offering versatility in different types of electrical systems, whether AC or DC voltage is being used.
- Housing Material: The transducer is housed in a black 6/6 nylon casing, which provides durability and resistance to environmental conditions.
Loudness & Performance
- Loudness at 2 Feet: The transducer is designed to produce a sound intensity of 88 to 101 dB(A), ensuring that the alarm can be heard clearly at distances up to 2 feet, with variations based on the voltage supplied.
- Loudness at Min Voltage (7.5V DC): At the minimum operating voltage, the transducer produces 80 dB(A) at 2 feet, which is still a significant output for general-purpose alerting.
- Loudness at Max Voltage (28V DC): When powered with the maximum rated voltage of 28V DC, the SC628AN can produce a loudness of 95 dB(A) at 2 feet, making it highly effective in noisy environments where higher sound levels are required.
Environmental and Operating Conditions
- Operating Temperature: Capable of functioning in a broad temperature range of -30°C to +65°C, making it suitable for use in both harsh and moderate climates.
- Storage Temperature: The transducer can be stored in temperatures ranging from -40°C to +85°C, ensuring it remains functional even when stored in extreme conditions.
- NEMA Ratings: Approved for use with NEMA 3R, 4X, & 12 enclosures when used with the ACC03 accessory, which provides protection against environmental factors such as dust, rain, and corrosion.
Installation
- Panel Mounting: For easy installation, designed for panel mounting. The recommended hole size for mounting is 1.25 inches (31.75mm), with the front thread compatible with a standard 30mm (1.181") hole. This makes it versatile and adaptable for various panel sizes.
- Knurled Nut: A knurled nut is used to secure the transducer to the panel. The maximum recommended torque for securing the nut is 10 in-lbs, ensuring the unit is securely mounted without damage.
- Weight: It has a typical weight of 1.6 oz (45g), making it lightweight and easy to handle during installation.
Compliance and Certifications
- RoHS Compliance: It is RoHS non-compliant, meaning it does not meet the Restriction of Hazardous Substances (RoHS) directive, which limits the use of certain hazardous materials in electrical and electronic equipment.
- Moisture Sensitivity Level (MSL): This transducer does not have a moisture sensitivity level, which typically applies to components sensitive to moisture during storage and handling.
- REACH Status: Itis unaffected by REACH, the European Union regulation that addresses the production and use of chemical substances.
- ECCN: The transducer is classified under EAR99, which refers to items that are subject to U.S. export regulations but are generally not restricted.
- HTSUS: The transducer is classified under the HTSUS code 8531.80.9041, which pertains to sound signaling devices.
