FAQs
KM/8021/M/370 is designed around ISO 6432 (DIN standard) with a 20 mm bore and G1/8 port size, enabling straightforward integration with common manifolds and panel mounting. The unit also features a magnetic piston and standard nose mounting nut, simplifying alignment and securing during retrofit or new builds. Verify clearance for the 370 mm stroke in your available space to ensure safe operation.
The cylinder operates from -10 to 80 °C and supports an air pressure range of 1 to 10 bar (15 to 145 psi). This broad range makes it suitable for diverse environments from cold hygienic lines to warm processing zones, reducing the need for multiple part variants and enabling a single cylinder to cover multiple applications.
Yes. The stainless steel barrel and durable internal materials provide high corrosion resistance ideal for washdown and CIP cycles. The magnetic piston supports reliable sensing, while adjustable cushioning helps manage impacts during high-cycle food handling. Together, these features satisfy hygienic and reliability demands typical of food processing and beverage lines.
The primary standard specified is ISO 6432 (DIN 6432) for interchangeability and mounting. While CE, SIL, or IP ratings are not listed in the provided data, the unit’s stainless construction, hygienic suitability, and magnetic piston align with industry expectations for food-grade automation equipment.
Adjustable cushioning reduces shock loads, extending seal life and enabling higher cycle rates. The magnetic piston simplifies feedback without extra sensors, improving control reliability. Stainless construction minimizes corrosion-related maintenance, contributing to lower total cost of ownership through fewer replacements and less downtime over the product’s life cycle.
