Allen-Bradley 42MTB-5000 Photoswitch Sensor Terminal Base

The Allen-Bradley 42MTB-5000 Photoswitch Terminal Base is a terminal-style power base for the 5000-series PHOTOSWITCH photoelectric sensors, providing the mounting platform and wiring interface between the sensor head and the control system. This Series B base is designed specifically for Allen-Bradley PHOTOSWITCH 5000 sensors and is documented by Rockwell as the terminal-base option for 5000-series devices. The base accepts 120 VAC input at 50/60 Hz, enabling powered operation from standard industrial power supplies, and it is built to withstand the rigors of harsh manufacturing environments. Used with the 5000 photoelectric family, it supports reliable object-detection tasks on conveyors, packaging lines, and other automation applications where AB photoelectric sensors are deployed. In service, the 42MTB-5000 functions as the electrical and mechanical interface that secures the sensor head while routing supply and signal connections to control equipment, simplifying installation and maintenance for end users.
