A liquid-tight fitting includes a connector, a seal, and a fastener member. The connector has a first and a second end, a shoulder located between the first and second ends, and a segment that extends from the shoulder to the first end. The segment has an outer surface. The seal has an inner surface in contact with the outer surface of the segment, an outer edge, and first and second seal ends joining the inner surface and the outer edge. The seal surrounds a portion of the segment such that the first seal end abuts against the shoulder. The fastener member is moveably secured to the first end of the connector, and has an end that engages the second seal end to cause the seal to compress between the shoulder and the fastener member. The seal member is adapted to deform toward the segment when compressed.

Hygienic electrical fitting with seal members

A device is provided for riding through brownouts, or transitory losses of control power applied to electromagnetic devices such as contactors and relays. An energy storage circuit stores charge that can be discharged into a contactor operating coil during partial or full losses of control power and for short durations. Momentary reductions in control power can thus be experienced without opening or otherwise changing the logical state of the contactor. Emergency stop override circuitry may be provided for preventing the ride-through performance, thus enabling the device to provide for both ride-through of short losses of control power, while permitting emergency stopping of loads due to the override.

Brownout ride-through system and method

A current sensing module is provided for contactors and similar switch gear. The current sensing module is packaged so as to be capable of mounting on a line or a load side of a contactor. The current sensing module may be eliminated where current signals are not needed, but can be added to the package where monitoring and control functions may benefit from sensed current signals on either or both sides of a contactor. The current sensing module may be configured as a single or multiple-phase device, and may output either analog or digital signals to local devices or to networked devices.
