Gimota GM modular series circular connectors

General introduction
GM modular connector are bayonet coupling circular connectors for outdoor use. The GM has seven module chambers that accept a variety of electrical, optical, or blanking modules. These modules may be thought of as independent connectors-within-the-connector and are each capable of separate insertion into the modular housing, complete with their own EMI protection and cable termination. GM connectors are codeable. Numbers 1 through 7 identify the individual module chambers. The module mountings have special guide grooves in the module chambers to ensure that modules are precisely positioned.
Five- or seven-pole modules are available as standard. The EMI adapter is crimpable and includes a heat-shrinkable cable strain relief.

GM connectors fit together as follows:
GM modular connector >> seven plug module >> populated with socket contacts

GM receptacles fit together as follows:
GM modular receptacle >> seven receptacle module >> populated with pin contacts

Material
The shell is made of aluminium alloy, with an epoxy-polyurethane surface coating. The bayonet
ring is coated in ethylene acrylate and complies with fire protection class UL94-V0 (flame
retardant, halogen-free). The module mounting is made of thermoplastic.
The connectors are RoHS-compliant.

Waterproofness
GM modular series connectors comply with protection class IP67 according to DIN 40050.
Moreover, each individual module is waterproofed, with an O-ring in the module mounting.
This design permits a highly waterproof connector system, also in the longitudinal direction.
An O-ring may be inserted in the receptacle clearance groove during assembly to ensure a
watertight seal between the receptacle flange and the panel to which it is fitted.

EMI screen
Plug modules are EMI protected by means of a crimp-fit screen, with a 360 degree arrangement
of spring contacts to provide screening continuity with the receptacle module. Receptacle
modules use a similar crimp-fit shielding screen. The connector and receptacle modules
together form a unit that ensures optimal 360 degree EMI screening.
