Many relays use soldered post coil terminatins inside the relay. In one case many years ago I found the SMT relay manufacturer used eutectic solder inside their hermetic relay. The SMT relay would fail because the solder balled up on the post, woul

You're correct: * Sealed relays should not be cracked or have moisture intrusion. * Hand soldering relays is going to be expensive. [Using a mini-solder pot for this might reduce some of the burden.] The good part is that the problem is gross enough

Hi, I am looking for a cheap Siemens safety contact relay for S-20 machine also call K2 relay. 3TK2804-OAC2. Anyone with info please contact me via email. I am also need to know the different between these two relays 3TK2804-0BB4 and the above metion

I hope you could able to help me how come the fuse blown out when we powered up the board containing relays. The relays rated current is 80milliAmps only compared to the 2A fuse.The relay contact form is SPDT.

Thank you for your long mail. I think the problem with machine is linked to the Blue relays on the cards which form part of the enable circuit. I think those relays form part of the safety circuit preventing me latching in the main safety relay. I am

Kindly explain to me how to calculate 24V DC Relay Coil Impedence for a 2PDT Relay.

that sounds like bad relay or relay control. are you in position to check it on relay pins? I would go from there.

Relay: Yes, you can drive a "DC" relay with AC. As long as the latching threshold is achieved, you can close the contacts. However, if the relay impedence is improperly selected, relay chatter can occur. I am confident MPM selected a correct rela

I have seen similar issues in the past. 1. We had an issue when the relays were installed a leg was bent over. This cracked the epoxy base and allowed water and flux to get in. 2. We have had to bake relays after washing. We would cut open the

So, project background first. I am in the process of designing a PCB that incorporates a microcontroller, LEDs, capacitive sensors and relays to control auxiliary light in my truck. I have the little stuff worked out and have it prototyped and workin
