FD-H and MD-H
Universal metal-bodied housing series, for PCB mount applications. Designed for use where connector is mounted such that connector enters horizontally and PCB is horizontal, ie angled pins. Panel cutout 24mm, connector can be mounted front or rear of panel. The insert on 3 pin types is removable from rear of connector, and is locked into one place once inserted - thus permitting assembly and testing of PCB before assembly into housing. The lock is a 30° turn internal latch operated by a small tip screwdriver - part 40-998 is a special tool with hardened tip for this purpose. Note that connectors are usually supplied with the locks unfastened for manufacturing user convenience. Most versions are available in 3 pin configuration only, certain models also available in 4 or 5 pin, as indicated in price lines below. Metal body offers RF protection. Standard connectors have countersunk clearance mounting holes to accept M3 bolts. The special 'M3' version of the connector has an M3 tapped thread, for speed of mounting. This obviously means that they can only be used rear-of-panel mounted.
FD-V and MD-V
As FD-H and MD-H, but for use with PCB mounted vertically, ie straight pins. Available in 3 pin configuration only.
