Interactive Catalog Replaces Catalog Pages Honeywell Sensing and Control has replaced the PDF product catalog with the new Interactive Catalog. The Interactive Catalog is a power search tool that makes it easier to find product information. It includes more installation, application, and technical information than ever before. These PDF files are no longer being updated and will be removed by January 2001.

Solid State Sensors Hall Effect Gear Tooth Sensors TYPICAL APPLICATIONS Automotive and Heavy Duty Vehicles: 1 Camshaft and crankshaft speed/ position 1 Transmission speed 1 Tachometers 1 Anti-skid/traction control Industrial: 1 Sprocket speed 1 Chain link conveyor speed and distance 1 Stop motion detector 1 High speed low cost proximity 1 Tachometers, Counters FEATURES 1 Senses ferrous metal targets 1 Digital current sinking output (open collector) 1 Better signal-to-noise ratio than variable reluctance sensors, excellent low speed performance, output amplitude not dependent on RPM 1 Sensor electronically self-adjusts to slight variations in runout and variations in temperature, simplifying installation and maintenance 1 Fast operating speed – over 100 kHz 1 EMI resistant 1 Reverse polarity protection and transient protection (integrated into Hall I.C.) 1 Wide continuous operating temperature range (– 40° to 150°C), short term to 160°C GT1 ORDER GUIDE GT1 Series GENERAL INFORMATION 1GT1 Series Gear Tooth Sensors use a magnetically biased Hall effect integrated circuit to accurately sense movement of ferrous metal targets. This specially designed I.C., with discrete capacitor and bias magnet, is sealed in a probe type package for physical protection and cost effective installation. Units will function from a 4.5 to 24 VDC power supply. Output is digital, current sinking (open collector). Reverse polarity protection is standard. If power is inadvertently wired backwards, the sensor will not be damaged. Built-in protection against pulsed transients to +60V, –40V is also included. Optimum sensor performance is dependent on the following variables which must be considered in combination: 1 1 1 1 PDFINFO Catalog Listing Description 1GT101DC Gear Tooth Sensor Target material, geometry, and speed Sensor/target gap Ambient temperature Magnetic material in close proximity p a g e - 0 5 2 MOUNTING DIMENSIONS (For reference only) 52 Honeywell 1 MICRO SWITCH Sensing and Control 1 1-800-537-6945 USA 1 F1-815-235-6847 International 1 1-800-737-3360 Canada Solid State Sensors Hall Effect Gear Tooth Sensors GT1 Series SENSOR SPECIFICATIONS All values were measured using 1 K pull-up resistor.

Any target wheel that exceeds the following minimum specifications can be sensed over the entire temperature range of –40° to 150°C with any sensing gap up to .080 in. (2,0 mm). This data is based on a 4 in. (102 mm) diameter wheel, rotating 10 to 3600 RPM. REFERENCE TARGET/CONDITIONS Characteristics will vary due to target size, geometry, location, and material. Sensor specifications were derived using a coldrolled steel reference target. See table, right, for reference target configuration and evaluation conditions. Target Diameter: 4 in.
