Switchtec's ultra slim relay socket gets screwless treatment for speed and safety

Standard sockets' use of normal screw technology is a time consuming process, having to ensure that all terminals are tightened securely and correctly to the specified level. Tool little pressure and wires can vibrate out, too much and copper conductors can be crushed and severed.

The use of the screwless socket removes this process, speeding up panel assembly times, 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, leading to costly repair bills and call out charges. But with this screwless socket version, 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.

Hongfa's HF41F follows the trend for ultra slim relays, and when fitted to a panel offers users a very high level of flexibility due to its compact size, contact rating and highly sensitive coil.

Aimed at panel builders and control manufacturers, the slimline relay interface module is ideal for use in PLC controls, air-conditioning equipment, other freestanding applications, and in many general Industrial applications.

For longevity and reliability, the relay contacts are SPDT 6A rated silver nickel oxide and have a maximum switching voltage of 400VAC. The relay is also available with gold plated contacts for specialised switching applications.

The fully featured, ultra slim (6mm) relay has a built-in green LED that indicates supply status, making the module quick and easy to commission and test. Supplied with a robust plastic retaining clip, the relay can be instantly removed from the module for quick substitution or isolation.

Offering versatility, seven operating coil voltages are available; 6, 9, 12, 24, 48-60, 110-125, and 220-240, all being AC/DC compatible. Able to operate safely in a very wide range of ambient temperatures (export opportunities), all devices offer an operating temperature range of -40 to +70 degrees C.

For multiple installations, a 2 to 20-way jumper link is available, allowing all 'common' terminals to be safely connected together. As well as being much neater, the jumper link also eliminates the need to cut, strip and terminate short lengths of cable, greatly reducing installation times.

The Hongfa 41F relay interface module has many applications. With its very low power consumption, its versatile 6Amp SPDT contacts, built in indication, and its 6mm wide construction, the unit is a manufacturing costs cutter and also a great selling point for OEMs and manufacturers.

The Hongfa 41F screwless socket can also be used with the solid state version of the relay, the plug-in HFS32. Suitable for controlling 2A, 48-440VAC (AC Version) and 5A, 0.1-57.6VDC (DC version), the HFS32 series is able to withstand a maximum surge current of up to 80A (depending on type) making the relays very well suited for high inrush or inductive applications.

Carrying the CE, UL and CUR approval mark, the 41F and HFS 32 series of relays and sockets from Hongfa can be installed into industrial applications with confidence. Switchtec is able to offer all the relays and sockets from stock at competitive prices.
