Teledyne AG Geophysical connectors

Bulkhead connectors with matching inline (cable) connectors

Teledyne AG Geophysical Bulkhead connectors. Here is Connector Catalog (PDF, 13 MByte). Sections named "NPT" refers to "National Pipe Thread Taper" standard.

AG Geophysical mod. 170x-F bulkhead connector. From AGM Marine -> 1000 Series -> Bulkhead -> Straight-Thread catalog (PDF, 13 Mbyte). (Here is also a local copy).

Matching AG Geophysical mod. AGM-100x-M inline connector. From AGM Marine -> 1000 Series -> Inline -> Standard catalog (PDF, 13 Mbyte). (Here is also a local copy).

AG Geophysical mod. AGP 2708 F bulkhead connector. From AGM Marine -> 2000 series -> AGP Bulkhead Connectors -> 1 5/16" Straight Thread p. 30 (PDF, 13 Mbyte). (Here is also a local copy).

Distance required to outer door of enclosure - minimum cable bending radius

Recommended clearance distance: 160 mm

Connector panels, 3rd deck - winterization

Draft layout of connector panel, 3rd deck port side, for 2+1 GI-Guns (each gun requiring 3 ea 2-way connectors), and 4 ea normal "Bolt" airguns (each requiring a single 4-way connector). Thus (3x3) + 4 = 13 bulkhead connectors are needed. Connector panel on starboard side should only accommodate 4 ea Bolt airguns - not any GI-guns. Click to enlarge.

Recommended minimum connector separation, under various conditions.

From CEE Norm UK Ltd catalog. This enclosure is made by Bals Elektrotechnik.

NOTE: 230Vac connector should be IEC 60309 type industrial - also splashproof. Eaton Crouse-Hinds series looks promising - here are the specifications.

Airgun/hydrophone bulkhead connector

Each airgun requires two cable pairs, one for firing the gun (the solenoid) and one for the sensor - 4 wires in total. All these four wires used in one connector, as shown below (click to open data sheet).
