One uncoupling electromagnet and ramp for use with tension lock couplings. The electromagnet goes underneath the baseboard, with the ramp on top between the rails. On applying current, the ramp rises and disengages any couplings standing over it.
The recommended power supply is 12V DC, and it should be operated by a SPST non-latching switch, as the electromagnet is not designed to take continuous current.
The actual size of the electromagnet is 38mm long x 25mm wide x 15mm deep. The ramp rod is 57mm long; the ramp is 40mm long and 10mm wide.
