Angled M12 device connector for THR

Increases efficiency in production

The 90° angled connector in M12 format is designed for automated production and enables efficient mounting processes. Thanks to its angled design, the new connector can be positioned flexibly on the PCB and can therefore also be used in confined spaces.

Main features

  • Angled design
  • For reflow (THR) processing
  • Voltages up to 250 V
  • Currents up to 4 A
  • Available in A and D codings
  • 4-, 5-, and 8-pos.
  • Unshielded version
  • Inverse pin connector pattern

Your Advantages

  • Suitable for pick-and-place: automated assembly on the PCB helps to increase efficiency in production
  • Optimized design: shifted center of gravity, thereby “effortless” standing on the PCB without locking clips
  • Flexible: easy positioning and alignment on the PCB even in confined spaces
  • Modular: compatible with the available THR housings

M12 device connectors for soldering processes

Future-proof in your application

The lead-free M12 connectors for wave soldering processes are RoHS II compliant without Exemption 6c. Due to their universal backward compatibility, you can smoothly integrate the connectors into your existing PCB layout.

Main features

  • Voltages up to 250 V
  • Currents up to 4 A
  • Available in A, B, and D codings
  • 4- and 5-pos.
  • Straight or angled design

Your Advantages

  • Standard pin assignments and codings for signal and data transmission with a uniform design-in design
  • Easy PCB mounting: two-piece connectors for wave soldering
  • Secure assembly: locking clips for fixing onto the PCB
  • Sustainable and future-proof: lead-free in accordance with RoHS II without Exemption 6c
  • Worldwide availability through global distribution channels

M12 push-pull connectors for Ethernet applications

Easy and space-saving data transmission

The M12 push-pull connectors designed for assembly for Ethernet applications enable reliable high-speed data transmission and impress with their extremely small space requirements. With fast-locking, installation is effortless – the connector is simply plugged into the device.

Main features

  • Push-pull internal locking
  • Compact crimp connection
  • X-coded for Ethernet applications
  • Number of positions: 8
  • Connection cross-section: 0.14 mm² ... 0.34 mm²
  • 360° shielding
  • Straight and angled versions
  • Degree of protection: IP65, IP67

Your Advantages

  • Easy installation: quick and reliable plugging, even in confined spaces
  • Significant space savings: extremely compact due to the small wiring space and high contact density
  • Safe use: reliable 360° shield connection
  • Robust connection: suitable for railway applications with high shock and vibration loads
  • Highly future-proof: standardized product range for worldwide availability

M12 push-pull connectors designed for assembly

Easy connection with Push-Lock technology

Two leading technologies in one M12 connector: the M12 connectors designed for assembly featuring push-pull fast-locking and Push-Lock connection enable tool-free conductor connection and provide a secure installation by simply plugging into the device port.

Main features

  • Installation: push-pull fast-locking
  • Connection method: Push-Lock connection technology
  • Data connectors: PROFINET CAT5 (100 Mbps), D-coded, 4-pos., shielded, straight and angled
  • Signal connectors: A-coded, 4- or 5-pos., shielded and unshielded, straight and angled
  • Connection cross-section: 0.14 to 0.75 mm²
  • Temperature range: -40°C to +85°C

Your Advantages

  • Quick and reliable connection even in confined spaces
  • Establish flying leads with connectors in male and female versions
  • Tool-free connection of rigid and flexible conductors with and without ferrules
  • Intuitive conductor connection with color coding and numerical coding of the contact levers
  • Long-term stability and vibration resistance of the PE connection and 360° shielding
