Operating Characteristics

Output Characteristics

Ambient Operating Conditions

Mounting, Soldering and Handling

These Sensors have been improved over previous Models and can withstand normal handling and automatic assembly as well as wave soldering at 280° C for 10 seconds, at 1/4" (6.3mm) from the case bottom. Contamination and fingerprints on the window surface should be cleaned with alcohol and a soft cloth. Avoid mechanical stresses on the case and leads.

Static Discharge

Additional safety features are used internally to make these sensors almost immune to electrostatic discharge.

Reference Voltage

The internal biasing voltage is accessible on pin 3. This voltage is used to drive the internal output amplifier. Offset voltage is referred to this point. This reference provides a low drift zero to allow for direct DC coupling of a subsequent comparator or A/D converter. The recommended maximum load on this pin is 20 uA (source only) to maintain electrical and thermal stability. Current loads greater than 20 uA may adversely affect performance; however, the output is short circuit proof.

Light Leakage

Slight sensitivity to visible light leaking through the glass-to-metal seal on the base may be observed.
