Information About 91MCE18-P3

The 91MCE18-P3 is part of Honeywell’s 91MCE Series of Global Limit Switches, offering a range of miniature compact switch configurations tailored for OEM and industrial use where space is limited. These switches combine a rugged zinc die-cast housing with epoxy sealing, achieving IP67 environmental protection suitable for outdoor and industrial settings. The switch lever actuates a snap-action mechanism that provides one normally open (NO) and one normally closed (NC) contact with direct opening (positive break) to ensure safe disengagement. Connection is made via a 3 m pre-wired cable exiting from the side, simplifying installation in equipment control panels or machine frames. Expected mechanical life for the series is up to 5 million operations, supporting long-term reliability.

Key Features:

• Actuator Type: Top Plunger with Boot Seal: designed for positive direct contact actuation with environmental protection.
• Contact Configuration: 1NO/1NC SPDT: provides both normally open and normally closed outputs for flexible control logic.
• Switch Action: Direct-Opening Snap Action: ensures reliable instantaneous switching and safe NC break.
• Connection Style: 3 m Side Exit Cable: long pre-wired cable simplifies installation without additional terminals.
• Housing Material: Zinc Die-Cast with Epoxy Seal: durable construction suited for industrial environments.
• Environmental Rating: IP67 Sealed: protects internal contacts from dust and water ingress.
• Mechanical Life: ~5 million operations: supports extended service life in high-use applications.
• Standards Compliance: CE, cULus, CCC Approvals: meets multiple global safety and performance standards.

The 91MCE18-P3 delivers the reliability and precision required for accurate position detection and machine control in automated systems and industrial equipment.
