What is the Wago 233-104?

PCB terminal block, 233 Series, CAGE CLAMP®

This PCB terminal block (item number 233-104) is designed for quick and easy connections. It offers the flexibility needed for different mounting types. This PCB terminal block has a rated voltage of 160 V and can handle currents up to 6 A. Ensure that the strip lengths are between 5 mm and 6 mm when connecting conductors to this PCB terminal block. Featuring one conductor terminal along with CAGE CLAMP®, this connector is highly versatile. Our CAGE CLAMP® connection provides a secure and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. Dimensions: 12.3 x 15.7 x 12.1 mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 0.5 mm². It has one level. Four potentials can connect four poles using the four clamping points The gray housing is made of polyamide (PA66) for insulation, the contacts are made of electrolytic copper (ECu), and the clamping spring is made of chrome-nickel spring steel (CrNi). The contact surface is coated with tin. This PCB terminal block is operated with an operating tool. The PCB terminal block is designed for THT soldering. The conductor is designed to be inserted into the board at a 30° angle.. The solder pins are organized over the entire terminal strip (in-line). They are 0.5 x 0.75 mm and 4 mm in length. Each potential has two solder pins.
