SECTION A - Series 93
Terminal Blocks for Printed Circuit Boards Series 93 screw connectors for printed circuit boards are some of the smallest available in the marketplace. Their space-saving design is based on a center-to-center spacing of 3.5 mm (0.138 in.). They are available both in solid versions from 2 to 24 positions as well as in 2 and 3 position dovetail (-T) blocks which can be clipped together quickly to provide the designer with the needed number of positions while maintaining center-to-center pin-spacing. Another advantage of the dovetail system is that both inventory and delivery times can be kept to a minimum. This series is end-to-end stackable while maintaining the 3.5 mm spacing.

We strongly recommend the optional wire protectors (-DS designation) to prevent damage to stranded wiring from the clamping screw mechanism. Solid wiring does not require wire protectors this makes insertion of larger wires easier in field wiring applications.

Type 938 has a rectangular wire entry design which can allow the use of a larger wire than type 930 the 938 can provide easier wire insertion.

Each product has a "How To Order" area as well as a complete listing of UL and CSA approval specifications, available options and accessories.
