Description
Product Overview
Product Name: Digital Output Module
Series: Honeywell D4D
Model Number: 10209/2/1
Manufacturer: Honeywell Sensing & Productivity Solutions
The Honeywell 10209/2/1 is a rugged, industrial-grade miniature precision snap-action switch from the renowned D4D series. It is designed for applications where reliable switching performance is required in a compact form factor. This specific model is a standard single pole, double throw (SPDT) switch, meaning it has one common terminal and two switched terminals (Normally Open and Normally Closed), providing a versatile output for control circuits.
These switches are engineered to detect the presence, absence, or position of a part or object in a wide range of industrial and commercial equipment. They are known for their long mechanical life, consistent electrical performance, and ability to operate in tough environments.
Key Features
- Compact Size: Miniature design allows for installation in space-constrained applications.
- Rugged Construction: Built with a robust metal housing and a high-strength operating lever for durability and resistance to mechanical stress.
- Precision Snap-Action Mechanism: Provides crisp, positive switching with minimal movement, ensuring high repeatability and long life.
- SPDT Circuit Configuration: (Form C) offers maximum wiring flexibility for both NO and NC circuit needs.
- Sealed Construction: Many variants, including this one, are hermetically sealed to protect internal mechanisms from contaminants like dust, moisture, and oils.
- Long Mechanical Life: Designed for millions of cycles, ensuring reliability and reducing maintenance needs.
- Various Actuator Options: The

Actuator Detail: Simulated Roller Lever (/1)
The actuator is a critical part of the switch. The Simulated Roller Lever is a one-piece lever designed to mimic the function of a roller lever but without a separate roller component. It provides a low-friction surface for the cam or part to act upon and is well-suited for applications with sliding or sweeping motions.
Typical Applications
This type of limit switch is ubiquitous in industrial automation and machinery. Common applications include:
- Industrial Machinery: Used as safety interlocks, door/gate position detection, and end-of-travel stops on CNC machines, packaging equipment, and conveyors.
- Business Equipment: Detecting paper jams, tray position, and covers in printers, copiers, and mail handling machines.
- Agricultural Equipment: Position sensing on tractors and implements.
- Vending Machines and ATMs: Detecting doors, locks, and component positions.
- Material Handling: Verifying the position of robotic arms, actuators, and lifts.
Important Notes
- Variants: The Honeywell D4D series has numerous variants with different actuators, electrical ratings, terminal styles, and sealing options. The
10209/2/1is one specific configuration. - Certifications: While this series is designed to meet international standards, always check the specific datasheet for certifications like UL, CSA, or CE for your application requirements.
- Wiring:
- Common (C): The center terminal.
- Normally Open (NO): Circuit is open until the actuator is pressed.
- Normally Closed (NC): Circuit is closed until the actuator is pressed.
- Installation: Proper alignment of the actuator with the target object is crucial to prevent binding and ensure long life.
