The B Series is the general-purpose indoor line of TRCONN push-pull self-locking connectors. It is the series to reach for when the equipment lives in a cabinet, an instrument enclosure or a machine control panel — protected from wash-down and rain, but exposed to vibration, dust and frequent mating. This page collects the data an engineer needs for a first selection.

The plug family
- TGG straight plug — the standard cable plug, in nut-tail and sleeve-tail versions.
- THG 90° elbow plug — same latch, cable exit turned sideways for tight routing.
- TEG front-sealed plug — O-ring at the mating face; also available with an anti-loss lanyard.
- TAG fixed plug — mounts through the panel so the harness is wired once inside the enclosure.
The socket family
- ZGG fixed socket — internal thread, mounts through a plain hole from the rear.
- ZEG outer fixed socket — external thread for thin panels and plastic housings.
- ZCG double-nut socket — front-of-panel installation without rear access; a long elbow-pin PCB variant reaches boards parallel to the panel.
- ZPG and ZXG — 90° PCB sockets for board-level mounting, with or without panel hardware.
- DHG floating socket — absorbs panel misalignment between the two halves.
Keying
All B Series connectors use a positioning-pin keying system. 0° (code G) is standard; 30° (A), 60° (B), 90° (C), 45° (J) and 155° (F) positions are listed in the catalogue. Specifying different key angles on same-size connectors is the standard way to prevent a wrong-line connection on a crowded panel.
Accessories
The accessory set follows the shell sizes: plug-side and socket-side dust caps, protective sleeves, and D-type cable clamps sized for 3.2 / 4.2 / 5.2 / 6.2 / 7.2 mm cable OD (codes D32 to D72). Cable OD on assemblies runs 2.5–8.2 mm with UV-, hydrolysis- and oil-resistant jackets in black, grey or orange.
