FAQs
Install the jam Nut Receptacle onto the panel, align the PCB with the four female contacts, and secure with the hold-down clips. The unit ships loaded with four PCB contacts and uses a 1/3 Bayonet coupling for quick mating. No backshell is required, and ensure mating orientation is correct for reliable sealing and IP68 protection.
The connector complies with IEC 61984 and UL 1977, and CSA-C22.2 No.182.3, with ROHS exemption 6.c. It also provides an IP68 rating and is designed for rugged industrial use, supporting reliable performance in regulated environments.
Yes. With IP68 sealing, UV resistance, and a wide operating temperature range of -40 °C to 105 °C, the connector is well-suited for outdoor and rugged field deployments in automation and sensor networks.
It has a current rating of 7 A (UL/IEC), a test current of 7 A, and test voltages of 250 V (CSA/UL) and 32 V (IEC). The contacts are gold-plated, and the assembly supports four cavities designed for PCB mounting.
The jam-nut receptacle with hold-down clips provides secure mounting and vibration resistance, while the 1/3 Bayonet coupling enables fast mating. With up to 250 mating cycles and UV stability, it supports lower maintenance costs and extended uptime in harsh industrial environments.
