Why Choose the TE Connectivity ZK2.5-YL PI-Spring Terminal Block?
The TE Connectivity ZK2.5-YL is a compact PI-Spring feed-through terminal block designed for fast, reliable conductor connections in industrial control panels, machinery and automation equipment. Part of the TE Connectivity ENTRELEC SNK series, this yellow terminal combines versatile spring-clamp technology with a space-efficient 5.2 mm DIN rail footprint.
PI-Spring technology supports efficient conductor termination while maintaining consistent spring pressure on the connected wire. Suitable conductors can be inserted using the push-in method, while the spring can also be opened with a screwdriver for conventional spring-clamp wiring, helping simplify installation and maintenance compared with traditional screw-operated terminals.
The ZK2.5-YL is rated at 24 A and 1000 V to IEC and accepts flexible conductors up to 2.5 mm² and rigid stranded conductors up to 4 mm² / 12 AWG. Its yellow polyamide housing provides clear circuit identification, while standard TH35 DIN rail compatibility makes it suitable for professional industrial panel construction.

Fast and Reliable Connections with PI-Spring Technology
PI-Spring terminal blocks combine push-in convenience with traditional spring-clamp functionality. Suitable conductors can be inserted directly for efficient panel wiring, while a screwdriver can open the spring clamp when required, providing flexibility for different conductor preparations while maintaining reliable spring-force contact.
The ENTRELEC SNK platform supports modular industrial panel construction, enabling compatible terminals and accessories to be arranged into organised DIN rail assemblies. With its narrow 5.2 mm footprint and yellow housing, the ZK2.5-YL is particularly useful where high wiring density and clear circuit identification are required.
Typical Applications
- Industrial control panels and electrical cabinets.
- PLC and distributed I/O wiring.
- Machine building and OEM automation systems.
- Process control and instrumentation equipment.
- Power and signal distribution assemblies.
- High-density DIN rail terminal installations.
- Circuits requiring distinctive yellow terminal identification.
