Snap Action, Limit Switches - 21EN322-RB

Applications and Working Principle

Snap action, limit switches are normally used for a variety of applications such as controlling in industrial machinery or automation systems, limit and positional switches, enclosure switches etc. The 21EN322-RB model from Banner Engineering is a rugged unit constructed from stainless steel and designed for harsh environments.The 21EN322-RB model can be used for a range of applications such as controlling two or more electrical circuits or for switching status indication of signal. It provides single or double pole, single or double throw (SPDT or DPDT) outputs, and withstands up to 10 amp loads. It is capable of withstanding up to 200 million operations, making it one of the most reliable models in Banner’s range. It can be used in applications up to 0-450 °F with UL and CSA certifications, and is IP67-rated for dust and water ingression protection.The 21EN322-RB model works on the principle of snap action. This means that when the switch is actuated, it will take a short, definite amount of time to change the state of the switch and revert back to its original position. This motion is quick and reliable, making the switch ideal for use in repeated operations. It is usually triggered by mechanical, magnetic or electrical contact, and is similar to the push button switches that many people are familiar with.The 21EN322-RB has a number of features that make it an adaptable and versatile piece of equipment. It features an adjustable travel stop for mounting flexibility, adjustable sensitivity and mechanical reset for silent switching on or off. It features two distinct coil or contact configuration options, allowing for both ductile and powerful operation. Additionally, the 21EN322-RB provides enhanced shock and vibration resistance, along with enhanced pneumatic, hydraulic and electro-pneumatic operation. Banner Engineering has a number of other limit switches available, which offer different features, capabilities and configurations. The 21EN322-RB model is the perfect choice for reliable, low-power switching operations in harsh environments. It is a versatile and adaptable piece of equipment that is capable of handling a wide range of applications.
