I am connecting a relay, but I am a bit confused by the datasheet..

Relay: TE Connectivity Potter & Brumfield Relays RZ03-1A4-D005 Digi-Key: PB1267-ND

Datasheet: http://www.te.com/commerce/DocumentDelivery/DDEController?Action=srchrtrv&DocNm=RZ&DocType=DS&DocLang=English

This is how I connected it:

Is it properly connected? Will it be NO?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

  • \$\begingroup\$ How can we tell if it's properly connected when you haven't shown us any context in the schematic (what's it connected to?) and you haven't explained what it's supposed to accomplish? \$\endgroup\$ – uint128_t Apr 12 '17 at 17:00

Based on your given product code and the datasheet your connection is correct.

enter image description here

It will be a NO relay where pins A1 and A2 correspond to the coil and pins 11x and 14x are open when coil is off and closed when coil is on.

  • \$\begingroup\$ Note that the diagram given by the datasheet and OP's part number does not correspond to OP's schematic symbol, so something may be amiss. \$\endgroup\$ – uint128_t Apr 12 '17 at 17:02
  • \$\begingroup\$ As a schematic symbol you're right, it's different, but the supplier uses the same package (8 pin) for a NO relay (RZ03-1A) and a NO-NC relay (RZ03-1C), given that, pins 121 and 122 would be present in his relay but won't be used. \$\endgroup\$ – Marcelo Espinoza Vargas Apr 12 '17 at 17:13
  • \$\begingroup\$ Good catch, looks OK then! \$\endgroup\$ – uint128_t Apr 12 '17 at 17:15
  • \$\begingroup\$ Thank you for taking your time and reply! I made the library for the relay myself, figured it was 8 pins on the relay even though it looks different from the above datasheet-image. Once again, thanks! \$\endgroup\$ – Martik Apr 12 '17 at 17:43
