Switchtec have introduced Hongfa screwless sockets, which serve to reduce installation time and provide a vibration-resistant connection. The sockets are of particular benefit to panel builders who are constantly striving to reduce production time, whilst improving performance and adding value.
Aimed at panel builders, OEMs, CEMs, equipment manufacturers and machine builders, the sockets are designed to be used with Hongfa's HF115F and HF18FH plug-in relays, and can be used in any application where control applications need to be wired in quickly and securely.
Standard sockets' use of normal screw technology is a time-consuming process, as all terminals have to be tightened securely and correctly to the specified level. With too little pressure, wires can vibrate out, and with too much, copper conductors can often be crushed and severed.
The use of the screwless socket removes this process, speeding up panel assembly times, and therefore reducing man-hours and increasing productivity. A second purpose or benefit is for use in areas of high vibration.
Traditional screw technology is susceptible to vibration, causing the screw to work loose, resulting in panel or product failure, and leading to costly repair bills and call out charges. When using Hongfa¹s screwless sockets, the cable is clamped by metal springs arms that are under a constant tension, ensuring a safe and reliable connection that is much less susceptible to vibration.
Aiding identification and deployment during manufacture and later in service, the screwless sockets are supplied complete with a white identification label and a relay ejector and retaining clip. All Hongfa sockets are suitable for mounting on 35mm Din rail (EN50022), they all carry the CE mark, and all terminals are rated to IP20 Œtouch proof.
The sockets are rated at 10A per pole, and feature an ambient temperature range of 40ºC to +70ºC. For safety and reliability, the sockets feature a 5000VAC insulation performance, are rated at 250VAC, and are made from a self-extinguishing high-grade plastic material.
