Proximity Switch Testing

Allows for fast field checks troubleshooting and or demonstration of 10 30 v dc sensors with a maximum sensor current draw of 100 ma.

Proximity switch testing.

A proximity switch is one detecting the proximity closeness of some object. For technical drawings and 3 d models click on a part number. Testing switches proximity solenoids contactors or relays. Pocket sized sensor tester with push type terminals makes wire connections quick and easy.

The proximity switch usually has 3 specific wires going to the switch. Dc 2 3 or 4 wire type sensors. Testers for proximity and photoelectric switches verify the signal output type of dc switches a red light indicates npn and a green light indicates pnp. Confirms operation of inductive photoelectric capacitive and ultrasonic sensors.

Make sure to put the machine in e stop when testing the switches or solenoids manually to check there diagnostics. Grounding hsi sensing can check a proximity sensor that contains a wire connected to the metal housing. The proximity switch generates a small radio frequency field. This test can be done in ac and or dc voltage.

The test voltage is typically 100 volts. 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. A proximity switch will be in its normal status when it is distant from any detectable object.
