The TE Connectivity 1SNA290261R1400, manufacturer designation DH2.5/5.2L, is a compact two-connection spring-clamp miniblock terminal designed for space-efficient wiring in industrial control panels, automation equipment and machinery. Part of the established TE Connectivity ENTRELEC SNA Mini Blocks Spring range, it combines reliable spring connection technology with a compact format for applications where installation space is limited.
The DH2.5/5.2L uses spring-clamp connection technology to provide consistent conductor contact independently of installer-applied screw torque. The spring connection automatically compensates for conductor creep, helping maintain dependable electrical contact throughout the service life of the installation while simplifying panel assembly and maintenance.
With a rated cross-section of 2.5 mm², an IEC rated current of 24 A and an IEC rated voltage of 800 V, the 1SNA290261R1400 is suitable for industrial control and automation wiring. Its compact 5 mm pitch, grey housing and two-connection configuration make it particularly useful where high wiring density and efficient use of panel space are required.
Spring-clamp terminal technology maintains conductor contact pressure without relying on installer-applied screw torque. This provides consistent electrical termination while automatically compensating for conductor creep, making spring terminals well suited to industrial installations where reliable long-term connections and efficient assembly are important.
The DH2.5/5.2L combines these benefits with a compact miniblock format and 5 mm pitch. Its small footprint allows designers to increase wiring density in electrical enclosures while retaining practical conductor capacities and electrical ratings for control, signalling and automation circuits.
