Sensor Module for Electricians

The Banner MA3AF is a sensor amplifier module designed for electricians and maintenance technicians who need reliable signal conditioning in industrial environments. It operates on a 10 to 30V dc supply and provides a complementary SPDT NPN transistor output for direct integration with control systems.

Replaces Failed Amplifier Units

This module serves as a direct replacement for a malfunctioning MA3AF amplifier in existing Banner sensor installations. The upgrade is worthwhile when the current module no longer switches cleanly or when the application requires the specific ON/OFF logic without timing functions that this part number 33168 delivers.

Steady Switching Under Continuous Power

Under sustained load the amplifier maintains consistent ON/OFF switching behaviour as long as the input voltage remains within the 10 to 30V dc range. The complementary NPN output transistors are rated for continuous operation without the thermal drift or timing variations that can affect modules with built-in delay circuits.

Questions about this item

What voltage supply does the MA3AF sensor module require for mounting?

The module operates on a 10 to 30V dc supply, so ensure your control panel or enclosure provides power within that range before wiring the unit.

Which wiring step is most often missed when installing the MA3AF amplifier module?

Connecting both complementary NPN transistor outputs (SPDT) to the load is the step installers skip; leaving one output unwired defeats the ON/OFF switching logic.

When should the MA3AF module (part 33168) be replaced in service?

Replace the module if the red housing shows heat damage, the NPN outputs no longer switch cleanly on a 10 to 30V dc supply, or after the three-year parts coverage period ends.
