FAQs
The UTS78D3SX32 uses a jam nut receptacle design for secure panel mounting. Position the connector through the panel cutout, thread the aluminium nut onto the receptacle body, and tighten to achieve a robust seal. The 1/3 Bayonet coupling provides quick mating, while the 3 PCB contacts ensure proper alignment. Ensure the insert is neoprene for additional ingress protection and connect the gold-plated PCB sockets to your circuit traces. This approach minimizes field reworks and supports vibration resistance in automated systems.
IP68/69K sealing is achieved through a combination of neoprene insert material, plastic shell, and the jam-nut mounting that maintains a tight seal in unmated and mated conditions. The operating temperature range of -40 °C to 105 °C and UV/vibration resistance further support outdoor and harsh indoor environments. The three-pin, gold-plated PCB contacts provide reliable electrical performance even under high-pressure washdowns and exposure to environmental contaminants.
Yes, the UTS78D3SX32 carries multiple certifications including CSA-C22.2 No.182.3, IEC 61984, and UL 1977, which align with common industrial and control-system requirements. RoHS exemption 6.c further supports compliance for restricted substances. For your specific application, confirm regional regulatory mandates and any additional certifications required by your customer base or end-market, as some projects may require explicit documentation or third-party testing.
The connector is rated for 7 A and up to 250 V (UL/CSA) or 32 V (IEC), with three PCB contacts and gold plating for reliable conductivity. It operates from -40 °C to 105 °C and has 250 mating cycles, making it suitable for repetitive connections in automation equipment. Environmental resistance includes resistance to gasoline, oil, acids, bases, and UV exposure, with a 500-hour salt spray rating to support harsh environments.
Ideal for control panels, industrial sensors, outdoor equipment, and compact automation assemblies, the UTS78D3SX32 provides a sealed, vibration-resistant connection with a compact footprint. Its 3-pin PCB configuration and 1/3 Bayonet coupling simplify installation in tight enclosures, while the jam-nut receptacle ensures durable mounting in rugged machinery. Use it to improve reliability, reduce maintenance, and streamline field diagnostics in harsh industrial settings.
