These gage heads are air-extend, spring-retract LVDTs (Linear Variable Differential Transformers) with precision linear bearings and internal conditioning electronics.  Operating on a nominal ±15VDC supply, the GCD-AE Series delivers an extremely linear, low noise ±10VDC output. These robust gage heads allow measurements over stroke ranges from ±0.05 inch [±1.27mm] up to ±1 inch [±25.4mm]. A removable blackchromed, hardened tool steel tip is threaded (4-48UNF-2A) to the working end. Internal construction prevents the core and shaft from rotating as they move longitudinally. The integral electrical connector (welded) provides for easy installation and allows replacing a damaged cable without sacrificing the sensor. Installation and adjustment are facilitated by an external ½-20 mounting thread and the two locknuts supplied with each unit.
