ENC-1-1-T-24 vs. ENC-1-1-N-24

ENC-1-1-T-24 that is Totem Pole (Push-Pull) This type can actively for suitable for direct connection to PLCs or counters that accept both PNP and NPN signals.
ENC-1-1-N-24 that is NPN Open Collector This output type is typically used to sink current to ground (drive low) and requires a pull-up resistor if a high signal (voltage) is needed. It’s a common choice for interfaces where the load is connected to the positive supply.
