M12 angled connector Harting M12 21 01 140 5 4‑pole — angled signal/data connector

Harting M12 21 01 140 5 angled 4‑pole connector is designed for reliable signal and data transmission in industrial environments. The compact M12 format integrates four contacts into an angled housing that simplifies cable routing and installation in confined spaces. Built for use with sensors, actuators and control devices, this angled signal/data connector offers stable electrical contact and a form factor intended to reduce strain on cabling where space is limited.

Advantages

The angled connector geometry allows neat cable exit and easier mounting in panels or machinery where straight connectors would obstruct components. Four contact positions provide standard signal and low‑power data connections, while the robust housing supports repeated mating cycles and reliable contact retention. Its compact dimensions help maintain tidy harnessing and reduce the likelihood of cable interference with nearby parts.

Suitable for

• Industrial sensors and transducers
• Actuators and valve controllers
• Machine control panels and I/O modules
• Automation wiring in tight or confined mounting locations

Key specifications

• Connector format: M12, 4 contacts (4‑pole)
• Mounting orientation: angled (right‑angle) housing for improved cable routing
• Intended use: signal and low‑power data transmission
• Contact arrangement: 4 contact positions suitable for typical sensor/actuator wiring
• Mechanical durability: designed for repeated mating and unmating cycles (industrial grade)
• Housing: compact design suitable for tight installation spaces

How to use

Prepare the cable by stripping the outer sheath to expose individual conductors and terminate them according to the device wiring diagram. Insert conductors into the connector contacts following the correct pin assignment and secure the contacts per the connector’s assembly instructions. Mount the angled connector on the device or panel, tighten the locking mechanism to the specified torque if indicated, and verify continuity and correct signal routing before commissioning the system.

Recommendations

Use the angled M12 connector where cable exit direction and space constraints require a right‑angle solution. Verify compatibility with mating receptacles and follow industry best practices for cable shielding and grounding to maintain signal integrity in electrically noisy environments.
