Switchcraft TB3M
XLR 3-pin Male Chassis / Panel Mount Receptacle


STYLE - Streamlined, miniaturized with nickel-plated metal and contrasting black plastic parts. Designed for light weight and unobtrusiveness. Also available in conductive black chrome finish.

CONSTRUCTION - Metal parts are rugged die-cast or precision machined with nickel-plating; plastic parts are molded of high dimensional-stability thermoplastic. Advanced design assures minimum weight consistent with strength and durability of cord plug housings of .413 inch (10.5 mm) diameter Weight: Series TA(*)F plug = .25 ounce (7 g); Series TA(*)M = .3 ounce (8.5 g).

INSERTS - Precision molded of thermoplastic for high mechanical and dielectric strength. Contacts and terminals are precision formed and plated for intimate contact and low resistance connections. Terminal numbers are molded on rear of male insert and on face of female insert for easy identification (except 6-pin male insert). Inserts can be supplied for OEM installation in microphones and instrumentation for optimum connecting reliability. For cord plugs, inserts can also be supplied for replacements.

LATCHLOCK - Positive latch system assures high integrity, vibration-resistant mating and transfer of shielding connection between housing, combined with simple, easy fingertip release.

STRAIN RELIEF - Rugged internal clamp holds cable tightly, while making a secure, low resistance connection between cable shield and housing.

FLEX RELIEF - Protects by minimizing cable bending stress at point of cable entry. Maximum recommended cable diameter is .115 inch (2.92 mm) when flex relief is used. By omitting flex relief (Series T(*)FL and T(*)ML only), cable up to .170 inch (4.32 mm) diameter can be used.

ASSEMBLY - Connector parts are mechanically keyed for simple assembly.

POLARIZATION - Mating male and female connectors are also mechanically keyed (latch and groove) so that it is impossible to mate them incorrectly.

"SCOOP-PROOF" FEATURE - Fully recessed pins on
male plugs and receptacles cannot be "scooped", bent or damaged by accidental mismating with mating connector.

COLOR ESCUTCHEONS - Attractive color escutcheons, Series TYEF, are recommended for use with Series TY(*)F and TY(*)FPC receptacles (when rear mounted) for attractive panel trim, as well as color coding one or more connectors. Colors are: red, black, gray, green, blue, white and yellow.
