Plugs and Receptacles
Plugs and Receptacles
Plugs and receptacles are the male-ended (plug) and female-ended (receptacle) connectors used to join electrical terminations and create a circuit.

They are characterized by their pinout, which properly aligns both the plug and receptacle so that the connectors fit in the correct orientation and join matching terminals. They are also defined by their physical construction, size, contact resistance, insulation between pins and optional locking mechanisms that secure connections into place.

Plugs and receptacles vary case by case, with plugs typically attached to the end of a cable and receptacles built into a machine or wall. Pinout configurations include anywhere from two to 80 pins. Straight blade connectors are most common, with two contact pins and a safety ground. Locking plugs and receptacles usually used a twist-style lock to secure the connection.

309 Series Pin and Sleeve products offer a complete range of products with 20A to 100A ratings, all units feature impact and chemical resistant non-metallic housings. Parts are color coded to clearly identify voltage configurations and units are compatible with other IEC 60309-2 brands. These devices offer offer NPT threaded cable housings and replaceable gasketed covers to facilitate field installation and maintenance requirements. Locking rings with neoprene gaskets providea watertight seal for use in harsh enviroments. Making the connection easy is a clock face that is used to represent the grounding contact position for all female connectors and receptacles. With the keyway at the bottom, the female grounding contact will appear at one of the twelve hour positions. To identify the system volatge identify the housing color and the hour location of the connector or receptacle grounding contact.
Mennekes offers a wide range of wiring devices for various applications. Receptacles are compact units that are ideal for panel mount installations. Receptacles have an oversized ground sleeve to prohibit mismating of different voltages. Inlets are ideal for generator or motor plug interface applications. Inlets are compact and can be surface mounted or mounted with available black boxes. In-line Plugs feature non-metallic housing with locking rings and gaskets for watertight protection. In-line Connectors feature dead-front construction for safety and use split brass solid sleeves.
