MARR-5 Features and Benefits
Features
• Miniature normally open switch
with 19.69mm x 2.66mm (0.775”
x 0.105”) glass envelope
• Capable of switching 1000Vdc at
up to 1mA
• Minimum voltage breakdown
2000 Vdc
• 10¹² Ohms insulation resistance
• Available sensitivity range 17-38 AT
Benefits
• Hermetically sealed switch
contacts are not effected by and
have no effect on their external
environment
• Low, stable contact resistance
• Zero operating power required
for contact closure
• Fit and forget durability
Applications
• Reed relays (particularly suitable
for high voltage breakdown
applications)
• Security
• Limit switching
• Telecoms line switching
• Office equipment
• Automotive applications

Notes
1) For details on electrical specifications, contact Hamlin.
2) Contact rating-Product of the switching voltage and current should never exceed the
wattage rating.
Contact Hamlin for additional load/life information.
3) Operate (inc. bounce) /Release Time-per EIA/NARM RS421A, diode suppressed coil.
4) Pull in Range-Contact Hamlin for tolerances available within this range.
5) Rating Sensitivity-The value at which contact ratings and operating characteristics are
determined. Derating may be required below this value.
6) MARR-5 Switching current is limited to 1ma at 1000 Vdc. Higher voltages and currents can
be switched using correct suppression circuitry (consult Hamlin).
7) Storage Temperature-Long time exposure at elevated temperature may degrade
solderability of the leads.
