Proximity Switch Testing

Insulation resistance this test measures the dc resistance across the open contacts measured in ohms with an ohm meter and the switch in a de energized state.

Proximity switch testing.

Pocket sized sensor tester with push type terminals makes wire connections quick and easy. Dc 2 3 or 4 wire type sensors. A proximity switch will be in its normal status when it is distant from any detectable object. Grounding hsi sensing can check a proximity sensor that contains a wire connected to the metal housing.

Testing switches proximity solenoids contactors or relays. Make sure to put the machine in e stop when testing the switches or solenoids manually to check there diagnostics. This test can be done in ac and or dc voltage. The proximity switch generates a small radio frequency field.

When this field is interrupted by a conductive object moving into the field the switch will detect this and cause a contact closure or opening based on the type of proximity switch. By definition these switches are non contact sensors using magnetic electric or optical means to sense the proximity of objects. A proximity switch is one detecting the proximity closeness of some object. For technical drawings and 3 d models click on a part number.

The test voltage is typically 100 volts. If not you could have uncontrolled motion from other sources due to conditions in the ladder logic. Allows for fast field checks troubleshooting and or demonstration of 10 30 v dc sensors with a maximum sensor current draw of 100 ma.
