Surface Mount Reed Switches

Low Power > MASM-14

MASM-14 14mm Close-Differential Reed Switch

RoꢀS

Description

The MASM-14 surface mount reed switch is a close-differential, sub-miniature,

normally open switch with a 14mm long x 2.28mm diameter (0.551” x 0.090”)

glass envelope, capable of switching 200Vdc at 10W.

This reed switch is a surface mount version of MACD-14. It has high insulation

resistance of 10¹⁰ohms minimum and a contact resistance of less than 100

milliohms. Both reed switches are intended for use in applications that require

low hysteresis between Pull-In and Drop-Out values.

Features

• Surface mount normally open

switch

• Low close/open hysteresis (close

differential)

Agency Approvals

• Capable of switching 200Vdc or

0.5A at up to 10W

Benefits

• Zero operating power required for

contact closure

• Excellent for switching micro-

controller logic level loads

• Hermetically sealed switch

contacts are not affected by and

have no effect on their external

environment

Note: Contact Littelfuse for specific agency approval ratings.

Notes:

1. Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life information.

2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A and

AN107 for details.

3. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load.

4. Breakdown Voltage - per MIL-STD-202, Method 301.

5. Storage Temperature - Long time exposure at elevated temperature may degrade solderability of the leads.
