Overview
The Honeywell 914CE2-3K is a miniature enclosed precision limit switch engineered for industrial automation and machinery control. As part of the MICRO SWITCH 914CE series, this switch combines compact design with robust construction, making it suitable for tight spaces and demanding environments. The unit delivers reliable snap-action switching with SPDT (single-pole double-throw) contact configuration, supporting both normally open and normally closed circuits simultaneously.
Key Features
- SPDT Snap Action: Single-pole double-throw (SPDT) miniature enclosed small precision limit switch with 1NO/1NC contacts and snap action function
- Top Roller Plunger Actuator: Precision roller design for consistent switching at low actuation force
- Fluorocarbon Diaphragm Sealing: Incorporates fluorocarbon diaphragm sealing to provide reliable protection, meeting NEMA 1, 2, 3, 3R, 4, 6, 6P, and 13, as well as IP66, IP67, and IP68 requirements
- Cable Termination: Cable or connector and basic switch terminals are encapsulated in an epoxy compound, offering superior resistance in harsh environments
- Versatile Mounting: 25 mm mounting centers for standardized installation
