CPST1.5/4L110-240V is a high-performance 4-wire sensor and actuator terminal block with LED indication, specially designed for modern industrial automation and electrical control applications. This terminal block is widely used in PLC panels, machine automation systems, control cabinets, sensor wiring circuits, actuator connections, and industrial distribution systems where compact design, quick wiring, and reliable electrical performance are essential.
The terminal block features push-in spring clamp connection technology, which enables quick, tool-free, and vibration-resistant wire installation. Unlike traditional screw terminals, push-in terminals reduce installation time, improve wiring reliability, and eliminate maintenance issues caused by loose connections over time. This makes the CPST1.5/4L110-240V an ideal solution for industries where efficiency, safety, and long-term reliability are important.
One of the key highlights of this model is its built-in LED indicator for 110–240V AC/DC operation, which provides clear visual status indication of the connected circuit. The LED allows technicians and maintenance engineers to easily identify power presence, signal status, and circuit operation without additional testing equipment. This feature significantly reduces troubleshooting time and improves operational safety in industrial environments.
The 4-wire terminal design makes it particularly suitable for sensor and actuator applications, where multiple wiring points are required in a compact space. It supports efficient signal distribution and simplifies wiring in automation panels. The slim 3.5 mm compact width helps save DIN rail space, making it ideal for high-density control cabinets and modern industrial panel designs.
Manufactured using high-quality flame-retardant polyamide (PA66) housing material, the CPST1.5/4L110-240V offers excellent mechanical strength, heat resistance, electrical insulation, and durability under harsh industrial conditions. It is engineered to perform reliably even in demanding environments with vibration, temperature fluctuations, and continuous operation.
This terminal block supports wire sizes from 0.2 mm² to 1.5 mm², making it compatible with a wide range of control and signal wiring applications. The push-in spring clamp connection ensures secure contact pressure and minimizes the risk of loose wiring caused by vibration or thermal cycling.
The product is designed for DIN rail mounting (DIN 35 standard), ensuring easy integration into control panels and switchboards. Its compact construction, LED status indication, and reliable electrical performance make it an excellent choice for industries such as manufacturing, automation, process control, robotics, electrical panel building, HVAC systems, packaging machines, and industrial machinery.
Whether used in signal monitoring circuits, sensor distribution, actuator control, or industrial automation panels, CPST1.5/4L110-240V delivers safe, efficient, and space-saving wiring performance with improved operational visibility through its integrated LED indication system.
