Bridge terminals

NEMA 5-15P male bridge terminals meet UL1659 requirements and allow all three wires to be terminated at the same time. They come pre-assembled, so loading the mold is as easy as plugging a power cord into a wall receptacle. Features include reduced carpal-tunnel fatigue, molding cycle time, and overall plug costs.

Pressure transmitters

Series W pressure transmitters measure differential pressures of liquids or gases from 6 to 150 psi and provide a plus or minus 1/2% differential pressure-range accuracy. Transmitters utilize high-accuracy piezoresistive sensors and have no moving parts to wear out. Features include stainless wetted parts that provide reliability in aggressive media, compact size, and a heavy-duty gasketted cast-aluminum enclosure. The transmitters are suitable for HVAC processes and automation monitoring applications.

Step motors

POWERMAX IITM hybrid step motors offer flying leads or cabling that terminate directly to the internal motor connections. The leads and cabling are available in a four- lead series or parallel configurations plus an eight-lead configuration to provide flexibility. The direct connection provides the highest possible interconnection integrity, especially in applications where motors are subjected to continuous lead flexing or vibration. The integral flying lead or cable versions feature 100% pin-to-pin isolation, and pins-to-lead receptacles that mate on all four sides.
