10-Channel Pneumatic Slip Ring
This 10-channel pneumatic rotary joint features M5 port size compatibility with 4-6mm air tubing, designed specifically for multi-channel vacuum applications requiring high-precision rotary connections.
Product Overview
Engineered with an aluminum alloy housing, this pneumatic slip ring integrates 10 independent M5 interface pneumatic channels. Optimized for negative pressure conditions, it reliably maintains vacuum levels up to -90KPa while ensuring leak-free operation at rotational speeds of 200 RPM. With an IP51 protection rating, it provides dependable multi-channel rotary sealing for automation applications including vacuum adsorption, gripping, fixing, and testing.

Frequently Asked Questions
Does the -90KPa specification refer to absolute pressure or relative pressure (gauge pressure)?
Typically, this parameter refers to relative pressure (gauge pressure), meaning 90KPa below standard atmospheric pressure (approximately 101KPa), corresponding to an absolute pressure of approximately 11KPa. Please specify your measurement requirements during product selection.
Can all 10 channels simultaneously achieve a vacuum of -90KPa?
Yes. Each channel is designed to support this vacuum level. Actual performance depends on your vacuum generation device's pumping speed, pipeline impedance, and total system leakage rate.
Can this product be used for positive pressure (blowing) applications?
While optimized for vacuum, it can typically handle low positive pressure blowing (0.3-0.5MPa). For primary positive pressure applications, we recommend our standard positive pressure rotary joint for better cost-effectiveness and sealing performance.
