1891348-1 is a Dynamic spring clamp series connector from TE Connectivity designed for efficient and reliable power and signal line interfaces, particularly in servo drive applications. The series features spring clamp design enabling highly reliable wire termination without screw fasteners or crimps, with multiple contact points that are all gold-plated for safe operation in harsh industrial environments. Available in four center line block configurations (D1900 at 3.5mm, D2950 at 5.08mm, D3950 and D4950 at 7.5mm pitch), the connectors support wire sizes from AWG24 to AWG10 (0.2 to 5.5 mm²) with rated currents up to 22A and voltages up to 600V AC/DC depending on series. The vibration- and shock-proof design with push-on locking system and audible feedback ensures long service life and improved efficiency, conforming to UL1059 standard for terminal blocks and making it ideal for industrial control systems, power distribution, and harsh environment applications.
