OMCH's Limit Switches Core Advantages

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.

High Protection Level fore Harsh Conditions

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.

Excellent Electrical Insulation Properties

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.

Robust and Durable Mechanical Lifespan

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.

Wide Industrial-grade Temperature and Humidity Range

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.

Low Contact Resistance and High Conductivity

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.

High Vibration and Shock Resistance Design

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 .

FAQs on Limit Switch

How many types of limit switch are there?

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.

What does a limit switch symbol look like?

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.

How to test a limit switch?

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?
