Dunco# MRR1AD 130 12DC. S.P.S.T., normally-open reed relay. Fits 14-pin DIP socket. 12Vdc 1453 Ohm coil. Coil polarity markings on relay are misleading. Correct coil connections are pins 6 and 13; polarity doesn't seem to be a factor (see spec sheet). Operates at lower voltages as well.
Customer Comments

Pinout and polarity important
On the Dunco# MRR1AD 130 relays I received, pin 13 is the negative side of the coil, pin 9 is the positive side, and polarity does matter. I've sent a corrected schematic to All Electronics customer service. Steve

Seems to work
Works fine. Although my pins are 9 and 13 for coil activation and both 1/8 and 7/14 for switch.

Works nice
Works fine, both with electric coil activation or as magnetic reed switch. Hard to find specs on this unit but works great

Relay Pin-Out
This is a magnet activated Reed sensor. There is no coil. The sensor is a magnetical operated Reed proximity switch A magnet must be within 1/2" of the device package to close the switch. The switch contacts are available at pins 1/14 and 7/8.
