1sna031831r0300 – bnms t5v-1

Why Choose the TE Connectivity BNMS T5V-1 Optocoupler Plug?

The TE Connectivity / Entrelec BNMS T5V-1, part number 1SNA031831R0300, is a plug-in input optocoupler designed for electrical isolation and signal interfacing in industrial control systems. It is specifically configured for a 5 V DC input and provides a solid-state output rated at up to 58 V DC / 30 mA.

Designed for use with compatible Interfast MS interface assemblies, the BNMS T5V-1 provides optical separation between the control input and output circuit. This makes it suitable for PLC, instrumentation and machine-control applications where a low-voltage 5 V DC signal needs to be transferred to an isolated solid-state output.

The compact plug measures 5 mm wide, 34.5 mm high and 38 mm deep and weighs approximately 4 g. Its removable plug-in construction supports straightforward installation and replacement within compatible Entrelec optocoupler bases, while the white housing helps identify the functional plug within an interface assembly.

Compact 5 V DC Optocoupler Signal Isolation

An optocoupler transfers a control signal across an electrical isolation barrier using optical coupling rather than a direct conductive path. In automation equipment, this provides a convenient method of interfacing electronic control signals while electrically separating the circuits on either side of the interface.

The BNMS T5V-1 is specifically designed for 5 V DC input applications and provides an isolated solid-state output capable of handling up to 58 V DC at 30 mA. Its compact plug-in design makes it particularly suitable for modular PLC and control-panel interfaces where space efficiency, isolation and straightforward component replacement are important.

Typical Applications

• PLC input signal interfacing.
• Industrial automation control panels.
• 5 V DC electronic control circuits.
• Signal isolation and decoupling.
• Machine control systems.
• Instrumentation and process control equipment.
• TE Connectivity / Entrelec Interfast MS interface assemblies.
