Position Monitoring Limit Switch YF Series position monitoring switch boxes are rotary position indication devices designed to integrate valve and NAMUR rotary pneumatic actuator with a variety of mounting options, configurations, and internal switches or sensors. They are specially designed to be suitable for small size pneumatic actuators and valves to reduce installation space, yet still provide high performance by equipping a variety of switches and sensors.
• Easy, precise cam set with no need for a setting tool. Red cam for close, green cam for open.
• Terminal blocks and socket type terminal strip with screws (max. 2.5mm2, 26 A @ 86°F, approved by UL, CSA).
• Visual position indicator directly engaged with driving shaft to provide continuous position indication. Red for close, yellow for open.
• High strength, chemical resistant and transparent polycarbonate dome for high visibility and reliability.

YH, YO & YE Series Limit Switch
The YH, YO & YE Series offers one of the most versatile platforms for adapting to a variety of valve systems. The explosion/flame proof design is CSA/FM approved and ATEX certified for use in hazardous environments. With the epoxy coated anodized aluminum enclosure it may be used in corrosive heavy wash down areas as well. In North America, FM and CSA have certified the YH, YO & YE Series for use without seal fittings in all hazardous areas. By passing special pressure piling tests, the enclosure was certified for this elite distinction. Now, a time-consuming procedure can be safely eliminated in Division 1 areas. The YH, YO & YE Series design offers two conduit entries with extra wire terminations on the terminal block. By terminating solenoid valves in the switch enclosure, significant savings are realized by eliminating a junction box, wiring, conduit materials and labor.
