M12 A-Code 4-Pin Y-Splitter Sensor / Actuator Cable

Last updated: 7 September 2026

Overview

M12 A-code Y-splitter cable branching one M12 4-pin male trunk into two M12 4-pin female branches. A-code M12 is the standard sensor / actuator keying defined by IEC 61076-2-101 and is used for low-voltage DC signal and 24 V DC sensor power. Each branch carries the same 4-pin assignment, so a single PLC card or distribution box can feed two sensors through one cable, reducing cabinet wiring.

Key Specifications

Construction and Materials

Trunk cable and two branch cables share the same 4 x 0.34 mm2 (22 AWG) stranded copper conductor bundle with PVC or PUR jacket. The injection-moulded Y-block sits inside a TPE overmould so the splice stays sealed to IP67 when mated. Pin assignment follows IEC 61076-2-101 A-coded 4-pin layout: pin 1 brown (power +), pin 2 white (signal), pin 3 blue (power -), pin 4 black (signal).

Typical Applications

• Pairing two 24 V DC proximity sensors, photoelectric sensors or valve solenoids into one M12 port on a remote I/O block or sensor hub; splitting one controller output into two actuator coils; doubling device density in a machine cell without running a second trunk cable back to the cabinet.

Compatibility and Fitment

Mates with any IEC 61076-2-101 A-coded 4-pin M12 socket. Not compatible with B-coded PROFIBUS, D-coded Ethernet, X-coded Cat6A or T/L-coded M12 Power sockets. For sensor-only signal wiring; not suitable for analogue 4-20 mA loops on shared trunks where shielding is required.

Custom Builds and Ordering

Length, connector pin count, coding and jacket material are all configurable. Common builds are listed in the attributes table above; everything else can be specified when requesting a quote. We do not publish a fixed list price because most M12 / M8 assemblies are quoted to a specific build. Lead time depends on length and connector tooling.

Packaging and Shipping

Each cable is individually bagged and labeled with coding, length and lot. Bulk packaging is used for OEM volume orders. Shipments leave our facility within the lead time confirmed on the order acknowledgement.

Quality and Compliance

This product family is designed around the connector codings listed above. The IEC standards referenced (IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111, IEC 63171-7, ISO 20653 for IP69K) define the mechanical keying, electrical ratings and sealing performance. Compliance verification (UL, CE, RoHS, REACH) is documented per build on request.
