t4011-021tcnsnap action, limit switches are used for a wide range of industrial applications. They can be used for monitoring the presence of an object, switching, controlling and monitoring various motors, controlling operation of various machines, actuating alarms when a limit is reached and controlling safety-related functions.

The T4011-021TCN consists of a snap action, switch mechanism combined with a limit switch. It is a hermetically sealed reed-type switch, which makes it reliable, with a wide operational temperature range. The T4011-021TCN is direct-mountable and is available in various terminal layouts, contact ratings, coil voltages and sizes.

The T4011-021TCN operates by a metal plunger that snaps or pops as it\'s pushed against the reed contacts on the switch. In it\'s resting state, the plunger is held off the contacts by a metal bar and a magnet. When the plunger is depressed, the metal bar releases its hold of the plunger, and the plunger is drawn to the contacts by the magnet. This causes the switch to close or open the circuit.

The T4011-021TCN can be electronically actuated using a pulse or reverse pulse of current from a controller or a separate power source. It can also be mechanically activated with a lever and push button. The magnetic core, plunger and magnets all contribute to the rapid operation of the switch, making it highly suitable for applications where quick and reliable switching is required.

The T4011-021TCN is highly durable and has a long life, which is advantageous in heavy-duty industrial applications. It is also moisture and dust resistant, which helps enhance its overall reliability. The strong magnetic field of the plunger ensures reliable operation and it has excellent noise characteristics, making it ideal for use in audio systems.

The T4011-021TCN is fully enclosed and hermetically sealed and complies with the specifications in IEC and UL standards. It is widely used in aerospace applications as well as telecommunications, computers, safety interlocks and motors. With its superb sensitivity, speed and reliability, the T4011-021TCN is a highly versatile switch suitable for a wide variety of industrial applications.
