Abstract: Systems (100) and methods (1500, 1600) for operating a Security Tag (“ST”). The methods involve communicating a Wireless Signal (“WS”) to ST (132) tag attached to an article (102) when a successful purchase thereof has been verified. WS includes a detach command. A mechanical component (922) of ST is caused to be released in response to a reception of WS at ST, whereby a pin (308) of ST transitions from an engaged position to an unengaged position without any human assistance or mechanical assistance by a device external to ST. An end (1002) of the pin resides within an aperture (1102) formed in a first portion (312) of an enclosure (302) spaced apart from a second portion (310) of the enclosure by a gap when the pin is in the engaged position. The pin is fully retracted into the second portion when it is in the unengaged position.

Abstract: Systems (100) and methods (1500) for operating a security tag. The methods involve: converting rotational motion of a pinion gear in a first direction into linear motion of a rack gear in a second direction so as to cause a pin to transition from an unengaged state in which the pin is retracted into a first portion of an enclosure to an engaged state in which an end of the pin resides within an aperture formed in a second portion spaced apart from the first portion of the enclosure; mechanically retaining the pin in the engaged position using a pawl that prevents movement of the pinion gear in a third direction opposed to the first direction; and automatically releasing the pawl in response to a reception of a wireless signal at the security tag, whereby the pin is returns to the unengaged state.

Abstract: A low profile explosion proof by containment enclosure includes a base wall having first and second edge sections that are joined with third and fourth edge sections to define a substantially planar surface. First and second side walls extend from the first and second edge sections, and third and fourth side walls extending from the third and fourth edge sections and are joined with the first and second side walls. The base wall, first and second, and third and fourth side walls define an interior zone. A cover is coupled to the first and second, and third and fourth side walls to enclose the interior zone and provide containment to any flammable events. At least one of the first and second side walls, third and fourth side walls, base wall, and cover includes one or more unobstructed openings that provide fluid drainage while also providing containment to any flammable events.

Abstract: An electrical connector receptacle for mounting within an explosion proof enclosure includes a flange portion having a first side, a second side and a centrally disposed aperture. Also included is a cylindrical member integrally formed with the flange portion and extending away from the first side. Further included is a plurality of apertures extending from the first side to the second side, wherein the plurality of apertures are configured to receive a mechanical fastener for mounting the electrical connector receptacle to a printed wiring board. Yet further included is an o-ring groove disposed within the first side and spaced radially outwardly from an outer surface of the cylindrical member. Also included is a plurality of mounting feet integrally formed with the flange portion and extending away from the second side to form an electrical bonding path to the printed wiring board.
