Informer™ Model INF-B Limit Switch.

• Rugged Marine Grade Aluminum Enclosure – rated for NEMA 4 (weatherproof), NEMA 4X (corrosion-proof), NEMA 6 (temporary submergence), NEMA 7 (explosion-proof) areas. The INF-B is CE, FM & CSA Approved for hazardous areas and is rated for IP67.  Aluminum covers are epoxy coated; clear covers are manufactured from Lexan.
• Rapid Enclosure Access – Screw-on cover allows quick enclosure access, saving valuable maintenance and set-up time.  The cover provides a vapor tight seal and allows entry to internal components in less than five seconds.
• Space Saving Visual Indication – the RED / GREEN indicator offers clear indication of the current valve position without sacrificing accessibility or adding to space requirements. Each also includes 0-100% scale.
• Quick Set Cams – Touch & Tune Switch Cams are set without the need for additional tools, further reducing calibration time.
• Faster Wiring – Pre-wired and labeled terminal strip enables quick, convenient attachment of field wires.
• Dual Conduit Entry – consolidate your components and minimize costs with the extra ½” NPT conduit entry. By terminating solenoid valves in the switch enclosure, significant savings are realized by eliminating a junction box, wiring, conduit materials and labor.
• Dual Shaft O-Rings – eliminate corrosion with top inner and bottom outer shaft o-rings that seal the drive bushing from external corrosives and internal contaminated that enter the enclosure.
• Eliminate Seal Fittings in Both Division 1 and 2 Areas – in North America, FM & CSA have certified INF-B units with proximity or solid-state contacts for use without seal fittings in all hazardous areas. By passing special pressure piling tests, the INF-B enclosure was certified for this elite distinction. Now a time-consuming procedure can be safely eliminated in Division 1 (aluminum covers) and Division 2 (clear covers) areas.
• Switch Options –
  • Economical, mechanical SPDT contacts for high power switching.
  • Proximity reed-type switches in both SPST & SPDT configuration, hermetically-sealed, ideal for computer input circuits.
  • Solid-state contacts, SPST, include bright RED / GREEN L.E.D. indicator lights to verify continuity and switch status, well-suited for 24 VDC or 120 VAC inputs.
