Description
The Triac EX Series hazardous location Limit Switch provides a compact design and low cost for both visual and remote electrical indication of rotary valve/actuator position.
The heavy duty design and wide variety of options make the EX Series the ideal multi-purpose Limit Switch for use in NEMA 4, 4X, 7 and 9 applications.
Features- Aluminum housing: Polyester powder coating
- Twin shaft body design: The primary shaft is located in the housing base and connects to a mating shaft located in the housing cover. This twin shaft feature allows easy and accurate housing assembly by eliminating the blind-hole configuration associated with competitive switch boxes
- Multiple switch options: Wide variety of mechanical, proximit and inductive switch options provide the most effective and economical choice for each specific application
- Visual position indication: The 3D rotor provides high visibility confirmation of valve/actuator position. The splined retainer allows adjustment to coincide with the exact valve position
- "Easy-set" cams: Splined, spring loaded and independently adjustable. This design offers tool-free calibration and positive vibration resistant engagement
- Multiple cable entries: Standard with two 1/2" NPT cable entries with option for third 1/2" or 3/4" NPT cable entry.
- Standardized mounting: ISO F05 mounting pattern and VDI/VDE3845 shaft
- Options: AS-i digital communication interface card, 3-position dribble control, 4 to 20 mA feedback transmitter, special terminal strips, NAMUR mounting brackets
