Why Choose the TE Connectivity ZDK2.5-22 PI-Spring Pluggable Terminal Block?
The TE Connectivity ZDK2.5-22 (1SNK805010R0000) is a grey PI-Spring feed-through and pluggable terminal block designed for fast, reliable connections in industrial control panels, machinery and automation systems. Part of the ENTRELEC SNK Series, it combines spring connection technology with a pluggable architecture that simplifies the connection and disconnection of electrical sub-assemblies.
The ZDK2.5-22 is specifically designed to increase wiring productivity by supporting pre-produced plug harnesses and plug-and-play assembly. This approach can reduce panel preparation and final installation time, simplify transportation of separately wired assemblies and make it easier to connect modular machine sections while reducing the risk of incorrect field connections.
Designed for 2.5 mm² applications, the ZDK2.5-22 provides four connection positions within a compact 5.2 mm spacing. It is rated at 24 A and 1000 V IEC, accepts rigid stranded conductors up to 4 mm² and flexible conductors up to 2.5 mm², making it a versatile pluggable connection solution for power and signal wiring.
