DC-Operated, Short-Stroke
Unguided Armature

"SU5" High-Voltage LVDT Series (DC)

These DC-EXCITED SHORT-STROKE LVDT models with UNGUIDED ARMATURE operate from a simple unregulated power supply to generate two high-level output signals: ą5 VDC and 0-10 VDC. For standard-output versions, see the "SU" LVDT Series. For hermetically sealed versions, see the DC "SUM" LVDT Series.

Each model includes high-quality electronics for energization and signal conditioning. Encapsulated, integrated electronics are suitable for operation in harsh industrial environments. All models are fitted with 2 meters (6.6 ft.) of shielded cable.

General Specifications are given below.
