Explosion-proof switches help customers meet increasing safety, regulatory requirements anywhere in the world.

Honeywell announced it has received Electrotechnical Commission (IECEx) approval for its MICRO SWITCH™ BX explosionproof switch products. With IECEx approvals, manufacturers can specify one Honeywell MICRO SWITCH™ BX-series switch for a machine that will potentially be used in Europe, Asia or North America.

IECEx is the Commission’s certification of explosive atmospheres, and incorporates all existing approvals. Current North American UL/CSA and European ATEX approvals are being superseded by IECEx recognition. Honeywell’s explosion-proof switch family obtained certification from the official global regulatory agency.

"The global nature of approvals is critical to pull together many countries’ and territories’ regulatory requirements,” said Leslie Neill, global product marketing manager for Honeywell explosion-proof and safety switches.

“This allows our customers to apply our products almost anywhere in the world and meet ever-increasing levels of safety regulations. Honeywell offers a wide range of differentiated solutions to meet virtually any application requirement,” explained Brad Kautzer, vice president and general manager of electromechanical line of business for Honeywell Sensing and Control.

By obtaining the newest global standard for safety, Honeywell customers around the world can be assured their explosion-proof switches may meet all local safety regulations.  Honeywell BX Series explosion-proof limit switches are rugged products used in hazardouslocations, such as control valves in petrochemical, waste handling or food processing plants.  Honeywell MICRO SWITCH™ explosion-proof limit switches may be most appropriate for use in dangerous environments where contamination or long distances may render other sensing technologies ineffective.

GKME Dual-Connection Series Enhances Safety, Productivity with Daisy-Chain Capabilities

Honeywell introduces the MICRO SWITCH GKME-series Dual Connection Safety Switch. This product line extension of the GKM series includes two pre-assembled connectors allowing for daisychain connection from switch to switch. The ease of installing GKME switches may reduce wiring time up to fifty percent, resulting in significant savings for the customer.

The GKME is designed to enhance machine safety – the removal of any switch indicates that a door is open and breaks the electrical safety chain. The design facilitates planned and unplanned maintenance by allowing modules of the machine to be easily removed and replaced, followed by plug and play of the safety switch.

Potential applications include packaging and assembly equipment; textile and printing machinery.

The 91MCE series limit switch is a compliment to Honeywell's existing product line of smaller, lower cost limit switches. Designed for modern industrial OEMs, the miniature package size fits in applications where space is limited. The small package size can be gang mounted for applications requiring more than two switch circuits. The 20mm mounting pattern meets most globally accepted mounting standards.

This product family offers the user many options including a variety of different actuator styles. Connection options include pre-leaded cable in various lengths or M12 connectors, both with side or bottom exits. Design flexibility is further enhanced with the availability of both slow action and snap action circuitry. Direct acting contacts are designed to open the NC contact when actuated. The epoxy-sealed rugged die-cast housing provides enhanced environmental durability.

FEATURES
• Direct acting contacts are designed to open NC contacts
   when actuated
• Sealed to IP67; NEMA 1, 4, 12, 13 suitable for outdoor
   applications
• CE, cULus, CCC approvals meet most global approvals
• Nine actuator styles offer design flexibility
• Slow-action and snap-action circuitry options
• Pre-leaded cable and M12 connector options
• Expected mechanical life: 5 million operations

NEW ELECTROMECHANICAL SAFETY SWITCHES AVAILABLE

Honeywell is committed to manufacturing safety solutions and we've doubled our product line to prove it. Honeywell offers a broad line of safety switches from miniature to heavy-duty switches. Honeywell's newest additions are a result of continuous development and brand commitment.
In addition to Honeywell’s current safety switch offering, we are proud to introduce several new product series.

HONEYWELL SAFETY SWITCH RANGE.pdf

KEY-OPERATED SAFETY SWITCHES
• GKE - IEC 20 mm mounting and IEC pricing are strong selling points of Honeywell's GKE product line. Available with 20mm or 1/2 inch NPT conduit, the GKE has two key openings and either 1NC/1NO or 2NC switching capability.
• GKN - Honeywell’s GKN switch has a common footprint and three contacts for safety monitoring, along with a flexible key. There are two switch stocking units (SKUs) for many applications. With four key openings, the GKN has up to three normally closed safety contacts and drop-in capability.
• GKS (available December, 2006) - Designed to trap-and-hold the key until the hazard has been removed, the GKS uses a solenoid for either Power-to-lock or Power-to-unlock Situations. This configurable basic allows combinations of four contacts and complies with North American, European, and Chinese standards. Potential applications include an access panel for a press, robotic machinery, and automated assembly areas.

NON-CONTACT SAFETY SWITCHES
• FF and FFS - These non-contact safety switches are a strategic fit into the Honeywell safety switch line as they complement the electromechanical offering. These non-contacting, hard-guarding solutions cope with Slop In the application or a large actuation window to reduce alignment issues between the switch and magnet actuator. Priced competitively, these switches have several potential applications, including pick-and-place packaging/assembly equipment, semi-con equipment, and printing machinery. Product series include: FF2, FF3, FF5, FF6, and FFS.

POTENTIAL APPLICATIONS, APPROAVALS, and HOUSINGS
These safety switches may be appropriate for the following applications:
• Packaging equipment
• Pick-and-place assembly equipment
• Semicon equipment
• Plastic molding equipment
• Woodworking machinery
• Textile machinery
