In the modern industrial automation production process, the travel switch is an indispensable key component. It realizes the output of position detection and control signals through direct contact with mechanical equipment, thereby ensuring the precise positioning, automatic operation, safe shutdown and other functions of the equipment.
Working principle of travel switch
The travel switch is a small current main control electrical appliance. Through the mechanical collision of the equipment running parts on the switch operating parts, the internal contacts are triggered to complete the on-off control of the circuit. Its basic functions include:
▶Limit the movement range of the equipment to prevent overtravel
▶Trigger control logic such as reversing, speed change, and shutdown
▶Achieve automatic round-trip control
This direct contact triggering method has a simple structure and stable performance, and is particularly suitable for automation equipment with clear structure and controllable movement rules.
Main product types of limit switches
In response to different industries and usage scenarios, KJT has launched a variety of customized models to meet diverse needs
How to choose a suitable travel switch
To ensure efficient and stable operation of the equipment, it is recommended to focus on the following aspects when selecting the model:
1. Application environment
High temperature: high temperature resistant type is required
Wet and outdoor: waterproof type is recommended
Flammable and explosive: explosion-proof type must be selected
2. Mechanical interface mode
Roller type, plunger type, lever type and other different actuators are suitable for different contact action modes
Choose the appropriate operation mode according to the direction, force and frequency of mechanical collision
3. Switch contact type
Normally open (NO), normally closed (NC), compound type (NO+NC)
Consider the control logic and signal redundancy requirements, choose single circuit or dual circuit type
4. Installation method
Panel installation, rail installation, screw fixing, etc., the selection should match the equipment structure
5. Electrical performance
The working voltage, current capacity, contact life, etc. need to match the control system to avoid damage to the switch due to overload
Travel switches are widely used in the following fields:
▶ Mechanical manufacturing: Position detection of moving parts such as stamping machines, machining centers, injection molding machines, etc.
▶ Logistics transportation: Detect whether the slider, conveyor arm, pallet, etc. are in place
▶ Metallurgical heavy industry: Limit protection under high temperature and high impact environment
▶ Elevator and lifting system: Position judgment and automatic stop control
▶ Coal mining and petrochemical industry: Use explosion-proof type to ensure safe operation of equipment
