Product Description
The Wurth Elektronik STAR-TEC 74272251 Snap Ferrite Sleeve is an advanced EMI suppression device engineered to meet the requirements of industrial, laboratory, and commercial cable installations. This product features a unique openable snap design with a 25 mm aperture, allowing for easy installation onto cables of varying diameters without requiring disconnection or rewiring. The STAR-TEC patented key technology ensures cables remain secure and protected from unauthorized removal, making it ideal for environments where tampering prevention is critical.
Manufactured from manganese zinc (MnZn) core material, the ferrite sleeve delivers reliable suppression of electromagnetic interference. Its impedance rating of 180Ω at 25 MHz, and 72Ω at 100 MHz, ensures robust performance across the low frequency range from 300 kHz to 30 MHz. This makes it suitable for use in lighting industry applications (including suppression of electronic ballasts such as neon tubes), measurement equipment, and installations requiring varying cable diameters.
The reusable key mechanism simplifies test and measurement workflows by enabling quick cable changes and adaptation in environments with difficult access. The internal security clamping system provides additional cable protection, enhancing the reliability and safety of the installation. Each packaging unit includes one key for secure locking and unlocking of the sleeve.
External product dimensions are: Depth 62 mm, Width 60 mm, and Height 55 mm, supporting optimal placement on cables and assemblies. The operating temperature range from minus 25°C to plus 105°C allows deployment in demanding industrial and commercial environments. Compliance with RoHS and REACH standards ensures suitability for regulated applications.
Industrial, laboratory, manufacturing, construction, test and measurement, and lighting installations benefit from the product's high performance EMI suppression, flexible cable accommodation, and secure locking. This sleeve is particularly effective for test setups, cable management, and permanent installations where repeated access and cable protection are required.
