OMCH limit switches’ key advantages demonstrate their ability to operate stably and reliably in various harsh industrial environments over extended periods. By employing stringent standards in protection ratings, mechanical lifespan, electrical insulation, and vibration resistance, OMCH ensures its products provide highly reliable, trouble-free, and stable position feedback for your projects, making them a cornerstone of product quality you can trust.
Most limit switch models have an IP65 and higher protection rating. Effectively protects against dust and water, ensuring long-term reliable operation of the product in harsh industrial environments with high water, dust, and oil content.
Insulation resistance is generally required to be greater than or equal to 100 megohms (at 500V DC). This provides a high standard of electrical isolation and safety protection, reducing the risk of failure and ensuring safe system operation.
The mechanical life of OMCH's limit switch can reach more than 1 million cycles. This significantly extends product lifespan, reduces frequent replacement and maintenance costs, and is particularly suitable for automated equipment operating at high frequencies.
The operating temperature range typically covers -10 degrees Celsius to 80 degrees Celsius (or 70 degrees Celsius), and the ambient humidity requirement is less than or equal to 95% RH.
Contact resistance is typically ≤25 milliohms or ≤30 milliohms. This ensures stable and efficient signal and current transmission, preventing malfunctions or other issues caused by poor contact.
Features high vibration resistance (e.g., 10-55Hz, 1.5mm dual amplitude) and high shock resistance (mechanical durability 1,000 m/s²). This ensures reliable signal output without interruption or false triggering in high-impact machinery .

OMCH limit switches are the critical link between industrial automation and reliable operation. OMCH’s products deeply serve seven key industrial sectors and more, ensuring precise position detection and safety control from high-frequency automation production lines to demanding heavy machinery.
Limit switches ensure that the moving parts of CNC machine tools and stamping machines stop precisely within a safe range to prevent mechanical damage.
Limit switch detects the accurate placement of pallets/materials and the location of safety doors or protective covers to ensure the continuity of the production line and the safety of personnel.
Limit switch is used for limiting the position of solar tracking systems in photovoltaic equipment, providing position feedback for wind turbine blades, and monitoring the positions of doors and drawers in high and low voltage switchgear.
In welding, painting, and stamping production lines, limit switches enable precise positioning of workpiece fixtures and interlock monitoring of protective doors, ensuring efficient and safe automated processes.
In aircraft manufacturing and high-precision testing, limit switches provide reliable position signals resistant to high vibration and wide temperature ranges, ensuring the accuracy of critical equipment actions.
Limit switches determine whether the robotic arm gripper or tooling fixture has accurately reached the designated position, providing a reliable logical premise for high-precision assembly.
In PCB/SMT production lines, limit switches provide high-speed, high-precision positioning for feeding and clamping mechanisms, ensuring the accuracy of the electronic manufacturing process.

Limit switches can be broadly categorized by their actuation method (e.g., roller plunger, lever, rotary, push button) and their housing type (e.g., standard, miniature, hazardous location). Click types of limit switch to know more.
The symbol typically represents the switch contacts. Common symbols include Normally Open (NO) and Normally Closed (NC) contacts, often shown with a mechanical actuator element.
The most common test involves using a multimeter to check for continuity across the contacts while manually actuating the switch. The NO contacts should close, and the NC contacts should open. An expert guide is here to help: how to test a limit switch?
