Usage Notes on Reed Sensors

Reed sensors are delicate products. Handle with extra care.

Cropping of terminals will change the operate, release, and differential values.

green rightDo's

When switching inductive or capacitive loads, use contact protection circuits.

Follow SMD soldering specifications. Exceeding these limits may permanently damage the sensors.

red wrongDon'ts

Do not use ferro-magnetic mounting parts, screws, or other ferro-magnetic devices nearby. This will affect the sensitivity (AT).

When manual soldering, do not subject to more than a 5 second dwell. This may cause damage to the seals, change sensitivity, and reduce solderability.

Do not drop. Dropping or subjection to shock will permanently damage the contact or alter the sensitivity (AT).

Switching voltage, switching current, and contact rating should not exceed maximum limits stated in specification sheets.
