The TE Connectivity 1SNA290201R1100, also identified as DR2.5/5.2L, is a compact two-connection spring-clamp feed-through terminal block designed for space-efficient wiring in industrial control panels, automation systems and machinery. Part of the established ENTRELEC SNA spring terminal block range, this miniblock combines reliable conductor termination with a compact angled design for high-density installations.
The DR2.5/5.2L uses spring-clamp connection technology to maintain consistent contact pressure independently of the operator, with automatic compensation for conductor creep. Front wiring entry provides convenient access during installation and maintenance, while the compact design allows terminals to be installed efficiently where control-panel space is limited.
With a rated cross-section of 2.5 mm², rated current of 24 A and rated voltage of 800 V, the 1SNA290201R1100 provides dependable feed-through connections for industrial control wiring. Its 5 mm spacing, grey polyamide housing and mounting compatibility with TH15 DIN rail make it particularly suitable for compact electrical cabinets and machine control systems.
Spring-clamp terminal technology maintains conductor contact pressure without relying on installer-applied screw torque. This helps provide consistent electrical connections and automatic compensation for conductor creep, while also improving resistance to the effects of vibration and reducing the need for connection retightening.
The DR2.5/5.2L combines these benefits with a compact angled miniblock format. Its 5 mm spacing and TH15 rail mounting help maximise available space inside smaller electrical enclosures, while front conductor entry keeps wiring points readily accessible during panel assembly and servicing.
