This is a direct-pressure plunger-type limit switch produced by CHINT Electric (CHNT) and Tengen Electric (TENGEN), and it is a commonly used component in the field of industrial control. The following is a detailed analysis:
- Product Positioning and Core Functions
YBLX-ME/8111 belongs to the category of master electrical limit switches, which is mainly used in electrical control systems to achieve the following functions:
- Motion mechanism limit: Trigger the on-off of the circuit through mechanical contact to limit the movement range of equipment (such as conveyors, lifting platforms).
- Direction/speed control: Cooperate with other components to realize the switching of movement direction or speed adjustment.
- Automated program control: Serve as a trigger node for logic control in machine tools and automated production lines.
Its core technical parameters include:
Rated voltage: AC 380V/DC 220V
Rated current: AC-15: 0.8A; DC-13: 0.16A
Protection class: IP62 (dust-proof and drip-proof)
Operating frequency: 20 times per minute
Ambient temperature: -5℃ ~ +40℃
- Structural Design and Operation Method
YBLX-ME/8111 adopts a direct-pressure plunger structure, and the contact action is triggered by directly pressing the plunger with external mechanical force:
Operating stroke: 5mm (plunger pressing distance)
Overstroke: 2mm (safety redundant stroke)
Total stroke: 7mm
Operating force: 15N (minimum triggering force required)
This design is suitable for scenarios that require precision position control, such as:
– Limit position protection of machine tool worktables
– Shelf limit in automated warehousing systems
– Station positioning of packaging machinery
III. Industry Applications and Procurement Channels
- Typical application scenarios:
– Manufacturing production lines: Prevent mechanical damage caused by excessive operation of equipment.
– Logistics automation: Path boundary detection of AGV (Automated Guided Vehicle).
– Construction machinery: Height limit of tower cranes and elevators.
- Procurement information:
Brands: CHINT Electric (CHNT), Tengen Electric (TENGEN)
Model correspondence: Series models such as YBLX-ME/8111 (direct-pressure plunger type) and YBLX-ME/8108 (adjustable roller arm type).

- Usage Precautions
- Installation specifications:
– It should be installed vertically on a fixed bracket to ensure that the movement direction of the plunger is aligned with the mechanical contact component.
– Wires with a cross-sectional area of ≥0.75mm² should be used for wiring to avoid excessive contact resistance.
- Maintenance recommendations:
– Regularly clean the surface of the contacts to prevent poor contact caused by dust accumulation.
– Check the elasticity of the plunger spring after every 100,000 operations, and replace aged components in a timely manner.
- Safety warnings:
– It is strictly forbidden to disassemble or adjust the internal structure when the power is on.
– Avoid using it in flammable and explosive environments; it should be used with an explosion-proof shell (special customized model).
- Possible Misunderstandings and Corrections
In the “YBXL-ME/8111” you provided, YBLX is a general code in the industry (Y stands for “limit switch”, and BLX is a company-defined prefix), while “YBXL” may be a typo. It is recommended to check the complete model on the product label or manual to ensure it matches the actual needs.
