YBLX-ME/8111 direct-pressure plunger-type limit switch

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:

1. 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:

1. 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).
2. Direction/speed control: Cooperate with other components to realize the switching of movement direction or speed adjustment.
3. Automated program control: Serve as a trigger node for logic control in machine tools and automated production lines.

Its core technical parameters include:

정격전압: AC 380V/DC 220V

정격전류: AC-15: 0.8에이; DC-13: 0.16에이

Protection class: IP62 (dust-proof and drip-proof)

Operating frequency: 20 times per minute

Ambient temperature: -5℃ ~ +40℃

1. 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, ~와 같은:

– Limit position protection of machine tool worktables

– Shelf limit in automated warehousing systems

– Station positioning of packaging machinery

III. Industry Applications and Procurement Channels

1. 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.

2. 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).

1. 사용시 주의사항
2. 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.

2. 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.

3. 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).

1. 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.
