Reed switch is a basic component of a reed relay, typically consisting of two iron spring plates. The following are some main parameters of reed switches:

Rated Current: The maximum current that a reed switch can withstand, usually measured in amperes (A).

Rated Voltage: The maximum voltage that a reed switch can withstand, usually measured in volts (V).

Static Contact Resistance: The resistance value of a reed switch in the closed state. Lower contact resistance is crucial for some precision measurement and control applications.

High voltage dielectric strength: The maximum voltage that a reed switch can withstand between two contact points in the closed state, usually measured in volts (V).

Pull in Current: The minimum current value required to switch a reed switch from a closed state to an open state.

Release Current: The maximum current value required to switch the reed switch from the open state to the closed state.

Operating Temperature Range: The temperature range within which a reed switch can operate normally. Usually expressed in degrees Celsius (℃).

Rated Life: The expected service life of a reed switch, usually expressed in the number of on/off cycles.

Wiring method: The wiring method of the reed switch can be direct insertion, pin insertion, or wire harness, etc. Choose the appropriate wiring method according to specific application requirements.

These parameters can usually be found in the product specification sheet or data manual of the reed switch. Different reed switches may have different parameter ranges, so when choosing a reed switch, it is necessary to match the appropriate model and specifications according to specific application requirements.
