Honeywell Technologies GLC Series Roller Plunger Limit Switch, SPDT, IP66, Die Cast Zinc Epoxy Coated Housing, 240V ac,

Honeywell GLC Series Limit Switch, 6A Switching Current, 240V Switching AC Voltage - GLCB07C

This limit switch provides precise position detection for industrial automation and control systems, using a roller plunger actuator to convert mechanical movement into an electrical signal. It is suited to demanding environments where a compact, enclosed switching device is required and supports standard conduit attachment for wiring.

Features and Benefits:

• SPDT snap-action contact reduces contact bounce for reliable switching
  Mechanical endurance of 10 million cycles enables long service intervals
  Switching capacity 6A at 240V AC for common control circuits
  IP66 enclosure rating protects against dust and powerful water jets
  Operating temperature range −40 to 85 °C maintains performance across climates
  PG13.5 conduit entry simplifies secure cable installation

Applications

• Suitable for end-of-travel detection on conveyor lines
  Ideal for machine-tool position sensing in production cells
  Used with motor starters for safety interlock feedback
  Can be used for door and access control in hazardous areas
  Suitable for assembly automation where robust actuation is required

What contact action is used and how does it behave electrically?

It employs a single-pole double-throw snap-action contact that switches rapidly between circuits, providing a clear changeover suitable for control logic and interlock circuits.

What construction materials contribute to its durability?

The housing is formed from die-cast zinc, offering mechanical strength and resistance to impact in industrial settings.

How Compact is the unit for panel or machine mounting?

The body is designed for space-conscious installations with a low profile and narrow footprint to fit confined mounting locations.

Which approvals ensure suitability for standard industrial deployments?

It carries recognised safety approvals, indicating conformity with multiple international electrical and safety standards.

What mechanical input force is required to actuate the switch?

The actuator requires an operating force of 16 N to engage the switching mechanism.

Standards

IEC/EN 60947-5-1
While IEC/EN 609747-1 covers general rules relating to low voltage switchgear and controlgear, IEC/EN 60947-5-1 specifically relates to control circuit devices and switching elements. The standard monitors the characteristics of devices, the electrical and mechanical requirements and the functional requirements.

EN50047
GLC and GLD limit switches are constructed from housing that meets EN50047. EN50047 applies to position switches with an automatic return actuator. Models that meet EN50047 feature standardised characteristics and dimensions (30.5 x 31.1 x 68 mm).

IP 66
A rating of IP 66 ensures that the limit switch units are protected against dust and low-pressure jets of water.

Sealed to NEMA 1, 4, 12, 13
NEMA 1 states that enclosures can be used indoor and offers a degree of protection against contact with the equipment enclosed.
NEMA 4 states that enclosures can be used either indoor or outdoor and provide protection against windblown rain and dust, hose directed water and splashing water.
NEMA 12 states that enclosures are intended for use indoors and offer some protection from dust, dirt, falling dirt and dripping non-corrosive liquids.
NEMA 13 states that enclosures are used indoors and offer a level of protection from oil, non-corrosive coolants, spraying water and dust.
