Home Product Info Ferrous proximity switches

Features

Proximity switches for detecting ferromagnetic materials such as ferrous metals.　Not react to such materials as aluminim or nonmagnetic stainless steel.

Mechanism

Sensors are deactivated because magnet is being pushed by springs and the detection circuit is within the N-pole magnetic field.
When a ferromagnetic object such as ferrous metals approaches the sensing face, magnet is pulled toward the object. Then, the sensing sirsuit detects S-pole and the switch is activated.

Common specifications

power supply voltage	DC 5～24V
Output specifications	NPN open collector :ON when in proximity.
Output specifications	If it is OFF in close proximity,（B） is added to the end of the model number.
Output current	15mA
Consumption current	8mA
Voltage Resistance	AC1000V
Voltage Resistance	1 minute/packaged part/ between the case
Insulation resistance	DC250V
Insulation resistance	Over 20MΩ in megohms/between the case
Operation temperature range	-20 ～ +85℃ (Without condensation)
Operating humidity range	20 ～ 95%RH

WARNING

・Ferrous proximity switches are not suitable for detecting tiny loose terromagnetic

materials such as iron powders because they are easily stuck to magnets.

・When mounting a ferrous proximity switch, please check that there ia no

ferromagnetic material at the back and lateral sides.
