AMP/TE CPC Circular Connector – 4/9/14 Pin, OEM 182919-1 / 206153-1 / 182647-1

TE Connectivity (formerly AMP) CPC (Circular Plastic Connector) series connectors for industrial control, SMEMA board handling equipment, and automotive sensor applications. The CPC series uses a bayonet-lock coupling mechanism — a quarter-turn rotation locks the connector, providing vibration-resistant mating without the thread engagement time of screw-lock connectors. OEM part numbers 182919-1 (4-pin), 206153-1 (9-pin), and 182647-1 (14-pin) are widely used in SMT pick-and-place machines, PCB handling conveyors, and automotive test equipment.

SMEMA Interface — Why CPC Connectors Are Used

SMEMA (Surface Mount Equipment Manufacturers Association) defines the standard electrical interface between SMT machines (printers, pick-and-place, reflow ovens, conveyors) for board-available and machine-ready signaling. The SMEMA interface uses a 4-pin connector — typically the CPC 182919-1 — carrying:

• Pin A: Board available signal (from upstream machine)
• Pin B: Machine ready signal (to upstream machine)
• Pin C: Common / GND
• Pin D: +24V or signal return (machine dependent)

The bayonet-lock coupling is specified for SMEMA because it allows rapid connection and disconnection during machine reconfiguration without tools, while providing vibration resistance during machine operation.

Frequently Asked Questions

How do I identify which CPC part number I need?

The part number is typically molded into the connector housing or printed on a label on the cable assembly. If the part number is not visible, count the pins and identify the coupling mechanism (bayonet = CPC series). Cross-reference the pin count against the three part numbers: 182919-1 = 4-pin, 206153-1 = 9-pin, 182647-1 = 14-pin. For other pin counts, consult the TE Connectivity CPC connector catalog.

Are CPC connectors compatible with Amphenol or other circular connectors?

CPC connectors are not interchangeable with MIL-DTL-5015, MIL-DTL-26482, or other military-style circular connectors — different coupling mechanisms, contact sizes, and housing geometries. CPC connectors are also not interchangeable with GX12/GX16 aviation connectors. Only mate CPC connectors with other CPC series connectors of the same shell size and contact configuration.

What crimp tool is required for CPC contacts?

TE Connectivity specifies the 91285-1 hand crimp tool (or equivalent) for CPC size 16 contacts, and the 91286-1 for size 20 contacts. The correct die must match the contact size — using the wrong die produces an incomplete crimp that fails pull-out testing. For production environments, pneumatic crimp tools with the appropriate applicator provide higher throughput and more consistent crimp quality.

Can I use CPC connectors outdoors?

Standard CPC connectors are rated IP50 (dust-protected, not water-resistant). For outdoor or washdown applications, use CPC connectors with the optional sealing plug and cable sealing grommet, which upgrades the rating to IP67. Alternatively, use Deutsch DT series connectors which are IP67 as standard without additional sealing components.

Typical Applications

• SMEMA interfaces: Board-available and machine-ready signaling between SMT line equipment
• PCB handling: Conveyor control connections, loader/unloader interfaces
• Automotive test equipment: ECU test fixture connections, end-of-line test system interfaces
• Industrial control: PLC I/O connections, servo drive interfaces, sensor cluster wiring
• Aerospace ground support: Test equipment connections requiring vibration-resistant bayonet coupling
