Advanced IP66 Enclosures Range Extended

Following customer demand, OKW have extended the highly successful ‘SMART-BOX’ range of plastic enclosures. These highly attractive IP66 enclosures have been designed for modern industrial electronics.

Typical applications will include heating and air conditioning controllers, monitoring systems, safety and security equipment and test and measurement devices.

Design engineers will appreciate the many unique design features of the ‘SMART-BOX’ series. For example, the case fixings screws and wall mounting shafts are hidden behind two hinged trims which are fitted in the lid.

The lid trims hinge wide to allow screw driver access, and are then clipped into the closed position. As a result, no visible fixings can be seen once the unit is mounted on the wall or machine.

The enclosures are molded in flame retardant ABS rated to UL 94 V-0. The standard colour is light gray, RAL 7035, and uniquely for this type of IP rated enclosures, the cases have a modern fine textured surface finish.

Internal screw pillars are moulded in the top and base parts for mounting PCBs, DIN-Rails, displays etc. Prices start from $30.

The ‘SMART-BOX’ enclosures are fully insulated to VDE 0100, and sealed to protection class IP66 (similar to NEMA 4X) for indoor and outdoor use. The molded gasket is designed for easy replacement during long term maintenance.

The range is now available in six standard sizes with external dimensions from 4.724” x 3.543” x 1.968” to 11.024” x 6.693” x 2.362”.

The cases are assembled by four rustproof stainless steel fixing screws which are positioned outside of the sealed interior. An optional key lock can also be fitted for security.

To aid installation and servicing, two plastic lid supports are also provided, and the wall fixing dimensions are molded onto the underside of the cases.

OKW can supply these ABS enclosures with additional holes for push-buttons, connectors and displays etc., plus silk-screen printed legends and logos, and RFI/EMI shielding.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
