The 221 Series Expands
Now with 10 Connection Points!
May 14,, 2025
The proven connection technology of the 221 Series just got even more versatile: a new double-deck terminal block with ten connection points is now available. Thanks to the lever technology, wiring remains as simple as ever: Lever up — insert conductor — lever down — done!
With this new terminal block, installers can connect up to ten conductors of the same potential without tools — quickly, intuitively, and in a space-saving manner.
As always, this model offers the familiar benefits:
- No loss of connection points compored to bridging solutions
- Compact, double-deck design saves space
- Suitable for fine-stranded conductors from 0.14 to 4 mm² and solid or stranded conductors from 0.2 to 4 mm²
nturally, the new version meets all the same technical standards and certifications as the existing 2-, 3-, and 5-conductor termal blocks of the 221 Series.

Power Supplies - 19" AC/DC Switch Regulators, only 3 HP wide
September 5, 2024
In the market segment of pluggable 19 inch switch mode power supplies, May is particularly well-positioned. Switch mode power supplies are highly efficient power supplies, that offer high power density and efficiency. They convert the input voltage into a stable output voltage and are generally smaller and lighter than linear regulators. Our long-standing partner nVent SCHrOFF offers a wide range of switch-mode power supplies with various output voltages and power ranges. A standout product is the 19-inch-AC/DC Slim Power SLE MKII power supply, which is only 3 HP wide.
HellermannTyton sustainable polypropylene cable ties
HellermannTyton's sustainable cable tie S50ROS is made from polypropylene, which means it has a significantly lower carbon footprint compared to standard cable ties made from other materials. It has a high tensile strength of 185 N, offers chemical resistance and is ideal for sensitive, smooth cables, as its non-slip construction prevents lateral movement and its external serration design reduces the risk of damage during installation and maintenance. This makes it perfect for a wide range of applications and also supports your sustainability goals.
