HEDT-9040

The HEDT-9040 and 9140 provide high temperature motion control detection at a low cost, making them suitable for automotive and industrial applications.

Note: Agilent Technologies encoders are not recommended for use in safety critical applications. Eg. ABS braking systems, power steering, life support systems and critical care medical equipment. Please contact sales representative if more clarification is needed.

The HEDT-9040 and HEDT-9140 are high temperature three channel optical incremental encoder modules. When used with a codewheel, these low cost modules detect rotary position. Each module consists of a lensed
LED source and a detector IC enclosed in a small plastic package. Due to a highly collimated light source and a unique photodetector array, these modules provide the same high performance found in the HEDS- 9040/9140 three channel encoders.

The HEDT-9040 and 9140 havetwo channel quadrature outputs plus a third channel index output. This index output is a 90 electrical degree high true index pulse. The HEDT-9040 is designed for codewheels which have an optical radius of 23.36 mm (0.920 in.). The HEDT-9140 is designed for codewheels which have an optical radius of 11.00 mm (0.433 in.).

The quadrature signals and the index pulse of HEDT-9040 are accessed through five 0.025 inch square pins located on 0.1 inch centers. Resolutions between 360 and 1024 counts per revolution are available. Consult local Agilent sales representatives for other resolutions.
