The CPSTG1.5/4 is a 1.5 sq.mm push-in sensor and actuator terminal block with integrated grounding connection, specially designed for industrial automation systems, PLC panels, machine control circuits, instrumentation wiring, and compact control cabinet applications. This terminal block is used in applications where sensor wiring, actuator signal distribution, and grounding continuity are required in a single compact terminal solution.
Unlike standard feed-through terminal blocks, the CPSTG1.5/4 features an additional grounding point, making it ideal for industrial machine control systems where proper earthing and signal wiring must be maintained together. The green-yellow colour coding helps identify grounding circuits quickly, improving panel safety and simplifying maintenance work. This makes it particularly useful in industrial automation panels, process control systems, and sensor-actuator field wiring applications.
The 4-wire sensor and actuator configuration allows efficient wiring of industrial field devices such as sensors, proximity switches, actuators, and control inputs. Modern machine control systems require compact wiring solutions that reduce panel space while maintaining organized and secure conductor termination. The CPSTG1.5/4 is designed specifically for this purpose, offering compact DIN rail mounting and efficient signal routing in limited cabinet space.
One of the major advantages of the CPSTG1.5/4 is its push-in spring clamp connection technology. Unlike screw terminals, spring clamp terminals maintain constant conductor pressure and reduce the risk of loosening due to vibration, thermal expansion, or continuous operation. This improves long-term electrical reliability in industrial machinery and automation applications. Push-in technology also speeds up installation and reduces wiring time for panel builders.
The terminal block supports 0.2 mm² to 1.5 mm² stranded wire and up to 2.5 mm² solid conductors, making it suitable for sensor circuits, control wiring, industrial instrumentation, and low-voltage automation applications. It is rated for 250V IEC voltage and 13.5A current capacity, ensuring dependable performance in industrial signal distribution systems.
Manufactured using high-grade Polyamide 66 insulating material, the CPSTG1.5/4 provides excellent dielectric insulation, heat resistance, mechanical durability, and safe long-term operation. The terminal body is designed for industrial use where vibration, continuous electrical load, and harsh operating conditions are common.
Its DIN rail mounting design ensures easy installation inside industrial electrical panels, switchgear assemblies, OEM machine panels, and control cabinets. The slim 3.5 mm width makes it extremely compact, helping engineers optimize terminal density while maintaining safe and organized wiring.
