Honeywell GLCC06D Miniature limit switch

Honeywell GLCC06D Micro Switch Global Miniature Limit Switch Overview

The Honeywell GLCC06D is a robust and reliable mechanical limit switch from the MICRO SWITCH™ Global Miniature Limit Switches, specifically the GLC Series. Designed to meet EN500447 mounting standards, this switch is engineered for global solutions and is suitable for a wide array of industrial, agricultural, transportation, and other applications that demand an environmentally sealed (IP and NEMA rated) switch with a compact form factor.

Product Detailed Description

• Function: The primary function of the GLCC06D is to detect the presence or absence of an object or the end of a mechanical travel limit by physical contact. When the actuator is pressed, it mechanically operates internal electrical contacts, changing the state of the circuit (e.g., opening a normally closed circuit or closing a normally open circuit).

• Actuator Type: It features a Top Roller Lever actuator with a Ø 12 mm x 5 mm [0.47 in x 0.2 in] metal roller. This type of actuator is ideal for applications where the activating object has a linear or rotary motion, allowing for smooth operation and reduced wear.

• Housing: The switch is encased in a durable, epoxy-coated zinc housing, providing excellent protection against harsh industrial environments.

• Contact Configuration: The GLCC06D has a DPST (Double Pole Single Throw) contact form with a 2NC (2 Normally Closed) slow-acting configuration. "Slow-acting" means the contacts change state slowly once the actuation point is reached, which can be beneficial in certain applications requiring precise timing or where contact bounce needs to be minimized. The normally closed contacts are positive opening, ensuring that the circuit breaks reliably even in the event of a contact weld.

• Environmental Sealing: It boasts high ingress protection ratings, making it suitable for wet, dusty, or outdoor environments.

• Global Compliance: Designed to meet various international standards and approvals, ensuring its suitability for worldwide applications.

• Excellent Environmental Protection: IP66/IP67 and NEMA 1, 4, 12, 13 ratings provide superior protection against dust, water, and oil.

• Positive Opening Contacts: This critical safety feature ensures that normally closed contacts are forced open when the actuator is operated, preventing dangerous situations even if contacts are welded.

• Global Compatibility: Designed to meet numerous international standards (CE, UL, CSA, CCC), making it suitable for global deployment and reducing inventory complexity.

• Compact Size: The miniature design is ideal for applications where space is at a premium, allowing for flexible integration.

• Versatile Actuation: The top roller lever actuator accommodates a wide range of actuating mechanisms, from cams to moving parts.

• Slow-Acting Contacts: Offers precise control and can be beneficial in specific applications where gradual contact change or reduced bounce is desired.

Precautions

• Correct Selection: Ensure the switch's electrical ratings (voltage, current), contact configuration (NC/NO, DPST), and actuator type are suitable for the specific application and load.

• Proper Installation: Follow Honeywell's installation instructions precisely. Ensure the switch is securely mounted and the actuator is correctly aligned with the moving part to avoid premature wear or damage.

• Electrical Safety: Always de-energize circuits before wiring or performing maintenance on the switch. Ensure proper grounding.

• Environmental Limits: Do not operate the switch outside its specified temperature and humidity ranges. While highly sealed, avoid direct, sustained high-pressure water jets unless specifically rated for IP69K.

• Actuator Overtravel/Pretravel: Ensure the mechanical system interacting with the switch does not exceed the actuator's maximum overtravel limits, which could damage the switch. Also, ensure sufficient pretravel for reliable activation.

• Cable Gland/Conduit Sealing: Proper sealing of the conduit connection is crucial to maintain the specified IP/NEMA rating. Use appropriate sealing compounds or fittings.

• Maintenance: Periodically inspect the actuator for wear or damage and clean the switch body to prevent debris buildup that could affect operation.
