Professional grade general purpose reed switch with rhodium contacts
Designed to give superior life switching relatively heavy loads
Normal applications include liquid level sensors, security systems, reed relays, proximity
sensors and counting devices
Ideally suited to handle normal 120 VAC loads.
Maintains low contact resistance over life switching light duty logic level loads

1. The specification for VA rating may sometimes be exceeded for less sensitive (higher AT) switches, and should be
decreased for very sensitive (lower AT) switches. Standex-Meder Electronics will run life tests specific to a customer’s
load upon request.
2. Breakdown voltage is measured in the presence of a radioactive ionising source. Switch leakage current is limited to
100 microamperes
3. Contact resistance measurements are made at 10ma from a 1-volt source, with 50% overdrive, using a 4-wire (Kelvin)
measuring system. Contact probes are located on 43 mm centres.
