We have found that proximity sensors work well for limit and home sensors. These 8mm diameter sensors are shielded to provide a more narrow and precise sensing area with a nominal 1.5mm sensing distance. They will operate from 10-30 VDC and provide a standard NPN output with a 3kHz switching frequency. The sensors come with a 6' three wire cable built in.
Optionally we can add a 3-pin Molex Microfit connector (male) which will fit out LMTS-4I junction box, so the sensor will plug right in. You can also get the sensor with the connector installed and the mating connector included. You will need a crimper to install the mating connector. Please see the link at the bottom of this page for a suitable crimper.
