DIN Rail End Clamp

DIN Rail End Clamp

A DINRail End Clamp, also known as an end stop or end bracket, is a small but essential component used in electrical panel assemblies. It is mounted at the end of terminal blocks or other DIN rail-mounted devices to secure and prevent lateral movement during operation, vibration, or transport.

Top 10 FAQs of DIN Rail End Clamps

What is a DIN rail end clamp?
A DIN rail end clamp is a locking device that prevents terminal blocks and other devices from sliding on the rail.
Why are end clamps important in control panels?
They ensure mechanical stability and maintain proper spacing, especially during vibrations or transport.
Which materials are used to manufacture DIN rail end clamps?
Typically polyamide (PA66), aluminum, or zinc-coated steel for strength and corrosion resistance.
Are end clamps reusable?
Yes, high-quality clamps can be installed, removed, and reused multiple times without damage.
What DIN rail sizes are supported?
Most clamps fit TH35 mm DIN rails (EN 50022). Some are available for G-type or C-type rails.
How are DIN rail end clamps installed?
They are mounted using screw locking mechanisms or snap-fit designs, depending on the type.
Do they require any tools for installation?
Screw-type clamps require a screwdriver; snap-fit clamps can often be installed without tools.
Can they be used in high-vibration environments?
Yes, especially metal clamps are ideal for industrial and transportation settings.
Are there different sizes of end clamps?
Yes, depending on the terminal block height and application, sizes may vary.
Do end clamps comply with international standards?
Reputed manufacturers ensure compliance with IEC and DIN EN standards.
