Micro Limit Switch: Compact and Sensitive Positioning Device

Micro Limit Switch: Compact and Sensitive Positioning Device

The micro limit switch is a small-sized limit switch with high sensitivity and reliable operation, used in scenarios requiring high positioning accuracy (e.g., precision machinery, medical equipment, and electronic devices). Its miniature design allows installation in tight spaces, while quick-acting mechanisms ensure accurate detection of tiny position changes. Ideal for applications demanding small size and high precision, this switch provides reliable position feedback and control in micro-electromechanical systems and automated devices.

Advantages

Sub-Millimeter Positioning Accuracy

Detects motion with ±0.1mm precision, critical for CNC machines, medical devices, and semiconductor equipment.

Ultra-Compact Size (12x8x5mm)

Fits into tight spaces (e.g., robotic joints, small actuators) where standard limit switches cannot be installed.

High Cycle Life (1 million operations)

Precious metal contacts ensure reliable switching in high-frequency applications (e.g., pick-and-place machines, automatic dispensers).

Related products

Micro limit switches are compact firmware peripherals to carry out precise detecting, motion control, position detecting, performing rollering actuating with 5A/250V AC, and using snap-action contacts with less than 10 milliseconds burst response. They also provide IP67 rating after compliance with EN 60947-5-1, thus are used in CNC machines essential for robotics.

Frequently Asked Questions

What level of positioning accuracy does a micro limit switch offer?

A micro limit switch provides sub-millimeter positioning accuracy (±0.1mm), critical for CNC machines, medical devices, and semiconductor equipment where precise motion control is essential to avoid errors or damage.
With an ultra-compact size (12x8x5mm), the micro limit switch fits into tight spaces like robotic joints, small actuators, or miniature electronic devices where standard limit switches cannot be installed. This makes it ideal for miniaturized automation systems.
The micro limit switch offers flexible actuator types, including lever, roller, and plunger designs, adapting to linear or rotational mechanical systems. This allows customization for specific motion profiles in diverse industrial or medical applications.
The micro limit switch operates with low operating force (0.05-0.5N), making it suitable for delicate mechanisms like lab equipment or optical instruments where excessive force could cause mechanical stress or damage.

Customer Reviews

Chen Liang
Sub-Millimeter Precision for Semiconductor Equipment

"In our chip manufacturing line, where precision is measured in microns, these micro limit switches are indispensable. The ±0.1mm positioning accuracy ensures our robotic pickers place wafers exactly in the right spot, reducing breakage rates. The ultra-compact size (12x8x5mm) fits into the tight spaces of our inspection machines, and the low actuation force (0.05N) prevents damage to delicate components. Critical for our high-precision processes."

Dr. Emily Zhou
Reliable for High-Frequency Testing Equipment

"Used in our lab's automated testing rig, these switches handle 500+ actuations per hour without wear. The precious metal contacts maintain low contact resistance ( <50mΩ), which is crucial for our electrical conductivity tests. The lever actuator design fits our linear motion stage perfectly, and the IP60 rating protects them from light dust in our cleanroom. Consistent performance over 10,000 cycles—excellent for high-duty applications."
