Overview
The ARO 116-218-33 is a plug-in solenoid coil designed for ARO pneumatic directional control valves. This coil is rated for 120VAC operation at both 50Hz and 60Hz, with a power consumption of 8.5VA at 50Hz and 6.9VA at 60Hz. The standard DIN 43650B connector interface ensures compatibility with a wide range of ARO valve bodies and proportional spool mechanisms.
Key Features
- Dual-frequency operation (50Hz/60Hz) — single coil rated for both international power standards
- DIN 43650B plug connector — interchangeable with ARO valve forms A, B, and common industrial standards
- Low power consumption — efficient 8.5VA (50Hz) / 6.9VA (60Hz) design
- Modular replacement — drop-in retrofit for existing ARO solenoid valve installations
- Robust industrial construction — proven field reliability in pneumatic control circuits
