Terminal Blocks – Accessories – Marker Strips

Marker strips are an important accessory for terminal blocks, and typically come in two different varieties – printed and blank. They attach to the terminal block and work to aid in the sorting of wires within a circuit. The purpose of marker strips is to provide a visual organization to improve the ability to identify both the appropriate destination of a wire and the purpose it serves within a circuit.

Marker Strips under Product Code 0809858:0071 are printed and feature adhesive backing that attaches to the desired terminal block or other item that needs identification or sorting. With printed marker strips, the coding can be customized to the needs of the user. They are made of a tough plastic material that is resistant to heat, oil, and moisture, and with built in UV inhibitors.

Marker strips provide an important advantage to a designer or user of a terminal block in that they serve to make task of organizing the terminal blocks much easier. The coding of the marker strips helps the user to understand quickly which wires should be attached to which terminals, thus reducing the possibility of errors in the wiring of the circuit.

Marker strips are manufactured to meet IEC, DIN or UL standards, giving the user confidence that they are using material that have been properly tested and certified. They are available with single markers and with multiples, and can be customized to the needs of the customer.

The mechanical strength of a terminal block connections depends primarily on the correct use of marker strips. Terminal marker strips should be chosen on the basis of the operating voltage and current requirements. For example, when using a 15 A terminal block, the marker strips should be selected that are rated to handle up to 20 A. The dimensions and shape of the marker strips should be appropriate to the device for which it is being used.

Here are some tips to keep in mind when using marker strips:

• Marker strips should only be attached the approved base material of the terminal block.
• Marker strips should not be attached to a jumper system.
• Marker strips must be set low to prevent accidental contact with a high voltage.
• The voltage and current rating of the marker strip is an important factor when selecting the correct size.
• When using a printed marker strip, try to use a darker color for better leak resistance.

By using marker strips properly, the user can be sure that they are being safe when creating and working with electrical circuits. The visual organization provided by marker strips makes difficult electrical wiring tasks easier, and in some cases even possible.
