What does this sensor/actuator box do in a machine wiring system?

It consolidates multiple discrete sensor/actuator signals from several M12 device connections into a single M23 master connection, reducing field wiring and making installation tidier. It is designed for 24 V DC field I/O distribution with integrated status indication.

How many devices can be connected to it?

It has 8 M12 sockets (5‑pin, A‑coded). Each slot is double-assigned, meaning two separate signal channels can be brought out per slot (commonly via pins 2 and 4), giving up to 16 I/O signal lines in total depending on your application.

What type of connectors are used for the field devices and the master cable?

Field devices connect via M12 5‑pin A‑coded sockets. The master cable connects via an M23 plug connection with a 90° (right‑angle) orientation and 19 positions.

Is it suitable for wet or dusty environments?

Yes. The enclosure is rated IP65/IP67, making it suitable for harsh industrial environments where dust ingress and water exposure can occur.

What voltage and current ratings should be observed?

Rated voltage is 24 V DC, with a maximum operating voltage of 30 V DC. Current carrying capacity is up to 2 A per I/O signal, 4 A per slot, and 12 A total across the box.

Does it provide local indication of power and signal status?

Yes. It includes local diagnostics with a green LED for supply voltage and yellow LED indication for I/O status (PNP signalling). This helps with quick visual checks during commissioning and troubleshooting.

What is the operating temperature range?

The specified ambient operating temperature range is -20 °C to +75 °C.

Is the master connection shielded?

No. This version is specified as unshielded, so it is typically used for standard 24 V DC sensor/actuator signalling where cable shielding is not required by the installation.

How is the M12 pinout typically used on the device ports?

The M12 ports are 5‑pin and commonly used as: pin 1 = +24 V, pin 3 = 0 V, pin 5 = PE, with pins 2 and 4 used as the two signal lines for the double assignment. The exact mapping from each slot to the M23 pins is defined by the internal pin assignment.

What degree of mechanical tightening is recommended for the connector interfaces?

For the sensor/actuator (M12) connections, a tightening torque of 0.4 Nm is specified. Where screw plugs are used for unused ports, 0.4 Nm is also specified.

What materials are used for the housing and contacts?

The housing is made from PA (polyamide). Contacts are specified as CuSn with Ni/Au contact surface finishing, and the master-side contact surfaces are gold-plated.

What approvals or compliance markings are typically associated with this unit?

It is listed with industrial approvals including UL Recognized / cUL Recognized / cULus Recognized and EAC, supporting use in a wide range of control cabinet and machine-building environments.

When would I choose a double-assigned sensor box rather than a single-assigned one?

A double-assigned design is useful when you want two independent signals per device port while still sharing common power conductors, helping reduce the number of home-run cables. It is often chosen when panel space, cable routing, or installation time are key constraints.
