SCHMERSAL travel switch

SCHMERSAL travel switchThe core is: mechanical triggering, electrical switching, safety and reliability; Operation and usage classification→Install→wiring→debug→Maintain five steps, emphasizing safety contact priority, travel matching, and anti vibration and anti misoperation throughout the process.

SCHMERSAL travel switchProduct and Principle (Quick Understanding)

Structure: Operating head (roller)/pendulum rod/Plunger), contact system（1NO+1NCForced disconnection), metal/Engineering plastic shell, reset spring.

Principle: Moving parts collision block pressing operation head→Internal lever driven contact action→Normally Open(NO)Closed, normally closed(NC)disconnect After the collision block leaves, the spring returns to its original position.

Safety feature: Forced disconnection of contacts（EN ISO 13849-1 PL d/SIL 2）When the contact is stuck, it can still be disconnected, suitable for safety circuitsSchmersal.

SCHMERSALSchmeisser travel switchapplication:

Limit switches with safety functions are suitable for sliding and hinge connections, and must be closed during use to ensure safety.

When used in combination with the security control module, all the components shown in this chapter1All level safety switches can reach the control category3or4According toISO 13849-1

1The further application of limit switches is mostly for various positioning functions. Various operating components can meet the requirements of many daily tasks.

SCHMERSALDesign and operation mode of limit switch:

in1On the level limit switch, the protective device and the positive disconnection are connectedNCContact points are positively connected.

The protection level of all safety switch enclosures isIP 67The safety switch can be installed in any desired installation position.

SCHMERSALSchmeisser travel switchWorking Principle:

A limit switch is an electrical switch used to limit the maximum movement position of mechanical equipment. Limit switch is a commonly used low current main control device.

1、limit switch(Travel switch) is a mechanical switch used to control the travel and limit protection of mechanical equipment. The mechanical triggering component and the limit switch executing component will make mechanical contact.

2Whether to turn on or off depends on other electrical components used in combination with the travel switch, and is not fixed. Overall, when designing circuits, it is necessary to meet the requirements of the electrical components usedAthroughBCut off,BthroughAJust cut it off.

Additional Information:

1、limit switchIt refers to a switch assembled inside a casing to protect the built-in micro switch from damage caused by external forces, water, oil, gas, and dust, especially suitable for places with special requirements for mechanical strength and environmental adaptability. The shape can be roughly divided into horizontal, vertical, and composite types.

2、limit switchThere are two types of limit switches: working limit switches and limit switches. Working limit switches are used to provide signals for the mechanism to move in place. The limit switch is designed to prevent accidents caused by mechanism actions exceeding the design range. The working limit switch is installed at the position where the mechanism needs to change the working conditions. After the switch is activated, it gives a signal and performs other related actions. The limit switch is installed at the farthest end of the mechanism to protect it from damage caused by excessive movement.

3、limit switchThe limit switch can be widely used for spatial coordinate control and limiting of lifting and transmission machinery in industries such as construction, ports, and mining. It consists of a high-precision large transmission ratio reducer, a mechanical memory control mechanism synchronized with its output shaft, and sensorsWTAUThe series limit switches are widely used in construction machinery due to their small size, multiple functions, high precision, adjustable limit, strong universality, and easy maintenance, installation, and adjustment.
