Product Description

The GCD-SE Series of heavy-duty DC operated gage heads enable high performance in environments containing moisture, dirt, and fluid contaminants. With a spring loaded LVDT, a precision linear bearing, and internal conditioning electronics operating on a single ended 8.5 to 28VDC input with minimal current draw, the GCD-SE is ideally suited to portable measurement applications in difficult environments. Internal EMI, ESD and
RFI protection, provide CE compliance when correctly installed. Synchronous demodulation ensures unsurpassed noise rejection.
These robust gage heads allow measurements over stroke ranges from 0 to 0.1 inch [2.54mm] up to 0 to 2 inches [50.8 mm]. The spring force is typically 9oz [255 grams] at fully compressed electrical stroke. A removable black-chromed, hardened tool steel tip is threaded (4-48UNF2A) 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.
