Datasheet A2TPMI  
The PCB versions are available with following connector assemblies:  
Connection type  
Manufacturer: Model No.  
Header  
Connector  
4 pin top entry  
4 pin side entry  
6 pin top entry  
6 pin side entry  
JST: B 4B-PH-K-S  
JST: S 4B-PH-K-S  
JST: B 6B-PH-K-S  
JST: S 6B-PH-K-S  
Housing: PHR 4  
Contact: SPH-004T-P0.5S  
Housing: PHR 6  
Contact: SPH-004T-P0.5S  
Contact Material: Phosphor bronze ; tin-plated,  
Applicable wire: 0.032 to 0.08mm2  
Insulation O.D.: 0.5 to 0.9 mm  
Note: Engineering samples will be delivered only with a 6 pin header and counterpart connector with  
350 mm cable.  
OUTPUT LOAD  
Capacitive loads which are applied directly to the outputs reduce the loop stability margin. Values of  
100 pF can be accommodated. Resistive load for the outputs should be held as small as possible (i.e. a  
large load resistance, Rload > 50 kW has to be used) in order to avoid an impact on the temperature sig-  
nal due to self heating of the module.  
RESPONSE TIME  
The response time to an object temperature jump depends on the time constant t of the thermopile and  
the signal processing time of the A2TPMI. The processing of the thermopile signal has a latency time  
(tlat) of max. 75ms caused by the time required for AD-conversion, DA conversion and signal process-  
ing. The following diagram explains the connection of these events

The A2TPMI has a sampling rate of 30 samples / second which results in a resolution of approx. 30ms  
for dynamic signals at VTobj
