Crimp Terminal

The MarKK crimp terminal from Molex features a high-conductivity alloy to offer up to 13.5 A per line based on a two-circuit system. The crimp terminal's spring-box design enhances reliability across an extended temperature range. The head- and tail-carried design eliminates the need for customers to monitor cutoff dimensions in application tooling, while four independent points of contact ensure a highly reliable interface. Pricing is $18 for 1000 pieces in quantities of 1 million.

Silicone Connector

Fujipoly America's Zebra FG-S silicone connector provides a current-carrying capacity of 30 mA per wire and exhibits an average contact resistance of only 0.35 V at 15% compression. The Zebra connector is manufactured with a silicone rubber core that is embedded with a single row of thin, gold-plated phosphor bronze wires. The wires are spaced on 0.10-mm centers and offer anisotropic conduction in the vertical orientation. The conductive core is sandwiched between two parallel insulator rows of silicon sponge for easy installation.

Jumper Bars

WAGO has extended the pole configurations for the insulated comb-style jumper bars used with the 231 Series Multi Connection System (MCS) MIDI. In addition to a two-pole configuration, three-, five-, seven- and 10-pole versions have joined the MCS MIDI lineup to provide additional flexibility. MCS MIDI Jumpers are specifically designed for CAGE CLAMP compatibility. The RoHS-compliant jumpers also feature an insulated touch-safe design for safety and suitability for both a 5-mm and 5.08-mm pitch. The 231 Series MCS MIDI terminates solid and stranded conductors up to 16 AWG with ratings of 15 A/300 V.

High-Temperature Connectors

Designated the CIR Series, ITT VEAM's circular connectors meet European CEN/TS 45545 standards governing railway fire safety. The connectors are capable of withstanding a high-temperature exposure period of at least 15 minutes at the ISO 834-1 heating curve, where maximum temperature is 800°C. Typical applications for the connectors include railway systems and transportation interconnects. Featuring a stainless-steel shell and ceramic insulation, the connectors are available with 35 size 12 poles at 40 A.
