Allen-Bradley 800MR-D2B Small Round Push Button Unit

Allen-Bradley 800MR-D2B is a non-illuminated, momentary-contact push-button unit (Bulletin 800MR) with a 22.5 mm round mushroom-head operator and a black cap, designed for rugged industrial use with Type 13/IP65 oil-tight enclosure compatibility. It provides two contact blocks (Left and Right), each configured as 1 normally open and 1 normally closed, enabling dual-circuit control from a single actuator. Termination is via small push-on connectors (two 0.110 in × 0.032 in) or a single 0.250 in × 0.032 in stab connector, offering wiring flexibility. The operator is plastic with a metal body, and the unit is rated for operation up to 300 VAC and up to 30 V DC across its contacts, with the listed current/VA values per the catalog data. The 800MR-D2B offers a mechanical life of at least 1,000,000 cycles and withstands shocks up to 100 g and vibrations up to 10 g. Operational temperature is 0 °C, storage temperature -40 °C, and humidity up to 50% at 40 °C, making it suitable for harsh environments. Certifications include UL, CSA, and IEC 529. This compact, non-illuminated push-button is ideal for control panels and heavy-duty machines where momentary signaling from a mushroom-head actuator is required in oil-tight environments.
