Traditionally, industrial relays were not suitable for the reflow soldering process, requiring an additional manual assembly step. The new reflow-resistant relay base RA5-1W from PTR Hartmann puts an end to that cumbersome process. Thanks to its clever design, the relay is easily inserted after the reflow process. The integrated suction surfaces eliminate the need for pick-and-place pads, saving additional processing time.
The RA5-1W is available as an SMD version (THR on request) and suitable for solid state and electromechanical relays with standard 3.75/5/5 mm pin layout. The feet are supplied in tape & reel and can thus be fully automated. Due to the horizontal placement, the SMD variant also saves valuable PCB space, which is a great advantage especially in compact applications such as DIN rail enclosures.
In addition to efficiency in production, the RA5-1W also offers technical security: the base complies with UL1059, IEC 60664 and DIN EN 61010. With a maximum load of 400 V / 6 A, it is suitable for almost all common slimline relays.
This combination of time saving, space saving and standards compliance makes the RA5-1W a valuable component in modern, automated production environments.
