E50 Modular Plug-In Limit Switch
Components are the industry stan-
dard with versatility of design and
high reliability for low maintenance,
installation and inventory costs.
Standard Viton gaskets, seals and
boots and a zinc die cast enclosure
provide exceptional chemical resis-
tance to the common coolants,
cleansing agents, and hydraulic flu-
ids found in machine tool, automo-
tive, waste water treatment and
other heavy-duty industrial applica-
tions. Mounting dimensions accom-
modate both U.S. and DIN standards
for easy retrofit installations. Super
bright 24 – 120V AC/DC LED indicat-
ing light versions simplify setup and
troubleshooting operations.

Heavy-Duty Plug-In Switches
(where shown)
Modular Limit Switches Provide Extremely Easy Installation,
High Reliability, and Low Maintenance and Inventory Costs
Product Features
■
Modular, plug-in components (head, body and receptacle) provide applica-
tion flexibility, reduced inventory and less downtime
■
Manufactured to take the physical and environmental abuse (including
cutting fluids and chemicals) of harsh industrial environments
■
Chemical resistant Viton gaskets, seals and boots are standard, and so are
captive, posi-drive screws
■
The switches have terminal identification on the nameplate for a visual
wiring checkout without guesswork. Heads and switch bodies can be
replaced without rewiring
■
E50 devices can be ordered in separate components or as complete assem-
bled switches
■
600V rating, ridge-topped contacts and wiping action assure continuity
even to logic level circuits
■
Keyed, four direction head positioning
■
Standard 5° pre-travel and 90° total travel
■
24 – 120V AC/DC LED and 120V AC neon indicating lights available
■
Rotary heads are field convertible CW, CCW, or both, without special tools
■
Epoxy filled, pin connector or pigtail pin connector receptacles available
