We have found that proximity sensors work well for limit and home sensors. These compact 8mm diameter sensors are only 35mm in length unshielded to provide an increased sensing distance 4mm. 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.
