Model 3721-MTC-1.5 / 3.0 

The Model 3721-MTC-1.5 / 3.0 cable is a 50-pin cable assembly (1.5m (5 ft) or 3.0m (10 ft) in length) terminated 

with a male D-sub connector on one end and a female D-sub connector on the other end.

WARNING 

Make sure the instrument that you are installing is in a powered-down state 
with all cables unplugged. Failure to install an instrument in a discharged 
state may cause personal injury or death from electrical shock. Do not 
exceed the maximum specifications of the switching module. 

 
 

To prevent electrical shock, observe the following safety precautions: 

 

• 

Both ends of the cable must be connected before applying any power 

 

to the system. 

• 

Remove all power in the system before connecting the cable to a 

 

switching module or external circuitry. 

• 

Both D-sub connector shells of this cable must be connected to a 

 

safety earth ground. A shock hazard exists when voltage levels greater  

 

 

than 30V RMS, 42.4V peak, or 60V DC are present. 

Cable maximum signal levels 

The Model 3721-MTC-1.5 / 3.0 cable is rated for 300V DC or 300V RMS. 

Maximum current rating 

The Model 3721-MTC-1.5 / 3.0 cable maximum current ratings are as follows: 

 

Single conductor: 4.4A 

 

Multiple conductors: 2.2A per wire 

 

Conductor gauge: 22 AWG 

Pin number identification 

Pin number identification for the Model 3721-MTC-1.5 / 3.0 D-sub connectors are shown in Figure 4 and Table 3 below
