A programmable logic controller (PLC) assembly. The PLC assembly has a PLC and a protective enclosure having a through-panel connector. The PLC is housed within the protective enclosure and electrically coupleable to the through-panel connector. The through-panel connector has a connector portion. The connector portion is configured for mating engagement with an electrical cable. The electrical cable is electrically coupleable to a PLC input device or a PLC output device.

Through panel wiring system

A wiring base for a bar code scanner or the like provides a conductive housing open at one face for connecting cables at various screw terminals to a circuit board providing signal processing for the signals and permitting various different-connections of the cables. The shields of the cables pass into the conductive housing to be terminated on conductive housing thereby enlisting the conductive housing as a shield around all the cables. Attachment of the scanning head to the upper face of the wiring base closes the housing to be free from the egress of dust or liquid and completes a Faraday cage around the connections while connecting two multi-pin connectors one within the base and one within the scanner, communicating the signals to the scanner. A visual indicator attached within the conductive housing indicates the presence of power and its polarity prior to connection of the scanning head to the conductive housing.

Wiring base for photoelectric scanning unit

A module interfaces a programmable controller to several serial communication networks over which data may be exchanged according to different protocols. A module has a central controller and a separate port circuit for each of the networks. Each port circuit includes a microprocessor and a shared memory to which both the central controller and the port microprocessor have access for the exchange of data. The central controller transfers data from the shared memories to a module output coupled to other components of the programmable controller. A removable memory cartridge stores a plurality of programs for execution by the port microprocessors to exchange data over the networks using different communication protocols. Configuration data is stored in the module defining which program is to be transferred from the memory cartridge into the shared memory of each port circuit. Protocol parameter configuration inquiries are stored for each program so that the user can be queried to select values for the parameters of the communication protocol used by the program.

An enclosure for a transducer includes a cylindrical housing and an end cap covering one end of the housing. A coupling ring engages an annular projection on the one end of the housing and a threaded portion of the end cap to hold the two elements in an abutting relationship. The housing has a threaded aperture therethrough. One of a series of different types of plumbing fittings, each having a common threaded projection, has the threaded projection received in the aperture of the housing. The end cap has a threaded aperture therethrough with one of a series of different types of electrical couplings received therein. Each of the couplings of the series has a common threaded projection which is adapted to mate with the end cap aperture. A set of stops is provided to prevent the end cap and the housing from rotating more than 360 degrees with respect to each other.

Enclosure for electrical sensor

A connector for coupling an optical cable including at least one optical fiber terminated in an optical contact to a phototransducer device is disclosed. A swivel member mounts the optical contact with a terminal end of the contact adjacent to an inner side of the swivel member. The swivel member is received within a connector body and is movable therein. A base member mounts the photo-transducer device with the photo-transducer accessible from an inner side of the base member. Mating surfaces are formed on the inner sides of the swivel and base members, to guide the terminal end of the contact and the photo-transducer device into alignment as the connector body is moved to a connected position adjacent to the base member. Biasing means between the connector body and the swivel member urges the swivel member toward the base member and allows the swivel member to align itself with the base member. Means are also provided for securing the connector body in the connected position. This construction provides an accurate and readily separable connection between the optical contact and the photo-transducer device. In one aspect, a swing arm arrangement provides general registration between the swivel and base members to facilitate accurate alignment between the contact and photo-transducer device.
