ER-18-310

The Airtec ER-18-310, ER-18-510, and ER18510 pneumatic limit switches are versatile and reliable components designed for various industrial automation applications. These limit switches, also known as roller type limit switches, feature a compact and robust design, making them suitable for use in harsh environments.

The ER-18 series limit switches come equipped with a 18mm bore cylinder and operate on compressed air. The ER-18-310 model features a 310mm stroke length, while the ER-18-510 model boasts a longer 510mm stroke length. Both models are available in normally open (NO) or normally closed (NC) configurations, providing flexibility based on specific application requirements.

Each switch consists of a cylinder, a piston, and a switch mechanism. When actuated by compressed air, the piston moves along the cylinder, causing the switch mechanism to activate, thereby sending an electrical signal. The switch mechanism is designed to provide positive contact, ensuring accurate and reliable switching action.

The roller type design of these limit switches allows for easy adjustment, as the roller can be positioned along the cylinder to set the desired switch point. The switch point can be adjusted by simply tightening or loosening the locknut on the roller. This feature is particularly useful in applications where precise positioning is essential.

The Airtec ER-18 series limit switches are manufactured to meet the highest standards of quality and durability. They are constructed from corrosion-resistant materials, ensuring long-lasting performance even in challenging environments. Additionally, they are compliant with various industry standards, including CE, ROHS, and ISO 9001:2015.

In summary, the Airtec ER-18-310, ER-18-510, and ER18510 pneumatic limit switches are durable, reliable, and versatile components suitable for a wide range of industrial automation applications. Their adjustable roller design, long stroke lengths, and compatibility with both NO and NC configurations make them an excellent choice for applications that demand precise positioning and reliable switching action.

Airtec ER-18-310, ER-18-510, and ER18510 pneumatic limit switches are widely used in various industries for automatic position control in pneumatic cylinders. Let's discuss the pros and cons of investing in these limit switches.

1. High Precision: Airtec limit switches offer high precision position control with minimal backlash, ensuring accurate and consistent operation.

2. Durable: The switches are designed to withstand harsh industrial environments, making them a reliable choice for heavy-duty applications.

3. Easy Installation: These limit switches come with a quick-connect coupling, making installation a simple and straightforward process.

4. Adjustable: The adjustable stroke length allows users to customize the switch to their specific requirements.

5. Cost-Effective: Compared to other position control systems, pneumatic limit switches like Airtec's are generally more cost-effective.

1. Limited Cycle Rate: The cycle rate of pneumatic limit switches is generally slower compared to electric switches, which may not be suitable for high-speed applications.

2. Energy Consumption: Pneumatic limit switches require compressed air to operate, which can result in higher energy consumption compared to electric switches.

3. Maintenance: Regular maintenance is required to ensure proper functioning of the limit switches, including checking air leaks and replacing worn parts.

In conclusion, Airtec ER-18-310, ER-18-510, and ER18510 pneumatic limit switches offer high precision, durability, and ease of installation at a cost-effective price. However, they have a limited cycle rate, higher energy consumption, and require regular maintenance.

If you're looking for a reliable and accurate position control solution for your industrial application, these limit switches are a great choice. However, if you require a faster cycle rate or lower energy consumption, you may want to consider electric limit switches instead. Ultimately, the decision depends on your specific application requirements and budget.
