T4011-L021SN

T4011-L021SN drives many typical automation features like decision making, controlling flow and also provides monitoring. Thus, it is classified as a limit switch.

Application Field

T4011-L021SN is a micro switch that comes with various functions like:

• Industrial/Automation
• HVAC/Heating and Ventilation
• Electrical Panels Control and Machines
• Security Systems, Burglar Alarms etc.

T4011-L021SN finds its application in the above-mentioned fields due to the features like contact configuration, mounting system, high insulation and much more. It has a compact design coupled with a durable construction that is suitable for continuous use of up to 10 million life cycles. One of the most reliable features of T4011-L021SN is its dielectric strength that is rated to be 3KV which makes it completely reliable in even hostile electrical environments. In view of its multiple switching specifications, power rated 2A and conventional thermal current 6A, this is one of the most suitable switches for diverse tasks that require the utmost in reliability and reliability.

Working Principles

The limits switch T4011-L021SN works on a time delay principle. The switch works similar to a pressure can in an air compressor. The switch is placed on the end of a tube or hose, and when the pressure of the air inside the tube or hose reaches a certain level, the switch triggers a reaction. This reaction is usually a relay or contactor that will activate the equipment that is being monitored or controlled.

The switch works on the principal of balancing different air pressures within the pressure can. The pressure can has two compartments that are filled with equal amounts of air at the same time. The air pressure in the pressure can is monitored by two discs that are connected to two metal rods. When the pressure inside the pressure can reaches a certain level, the metal rods will move and make contact with the switch. The switch then triggers the response. The response may be a simple “On/Off” command or a complex electrical action.

The switch is suitable for many uses in the automation and industrial worlds. It can be an important part of safety systems for controlling hazardous operations or detecting water levels. It can also be used to monitor performance in production lines or be used to troubleshoot machines. The versatility and durability of T4011-L021SN makes it one of the most popular switch devices used today.
