MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series

SIDE ROTARY: Available levers provide greater versatility.

Heads may be positioned with shaft on any side. All are mo-

mentary action except maintained head (LSN Series).

LSA - Standard: 15° maximum pretravel,

5° (single pole) and 7° (double pole)

maximum differential travel, 60° mini-

mum overtravel. Operating temperature

range from -12°C to 121°C [10°F to

250°F].*

LSR - Low operating torque: 0.19 Nm [1.7 in lb] maximum

operating torque. 60° minimum overtravel, 15° maximum

pretravel. Operating temperature range from -1°C to 121°C

[250°F to 250°F].*

LSN - Maintained contact: Maintained on counterclockwise

rotation and reset on clockwise rotation, and vice versa. Oper-

ating temperature range from -1°C to 121°C [30°F to 250°F].

LSP - Low differential: 3° (single pole) and 4° (double pole)

maximum differential travel. 68° minimum overtravel, 7°

maximum pretravel. Operating temperature range from -12°C

to 121°C [10°F to 250°F].*

LSH - Low torque, low differential travel: Features low

operating torque and narrow differential travel. 68° minimum

overtravel. Operating temperature range from -1°C to 121°C

[30°F to 250°F].*

LSU - Low pretravel: 5° max. pretravel, 70° min. overtravel.

Operating temperature range from -12°C to 121°C [10°F to

250°F].*

LSL - Sequence action: Delayed action between operation

of two poles. 48° minimum overtravel. Operating temperature

range from -12°C to 121°C [10°F to 250°F].*

LSM - Center neutral: One set of contacts operates on the

clockwise rotation, and another set on the counterclockwise

rotation. 53° minimum overtravel. Operating temperature

range from -1°C to 121°C [30°F to 250°F].*

LST - Momentary action with extra low torque: 12 in oz of

operating torque with momentary action. Operating tempera-

ture range from -12°C to 121°C [10°F to 250°F].*

LSS - Gravity return: Has no return spring mechanism in

actuator head so weight of the lever must provide the return

force. Extremely light operating torque (5 in oz max.) is useful

in conveyor applications and can be operated by small or

lightweight objects. Operating temperature range from -1°C

to 121°C [30°F to 250°F].*

TOP ROTARY: Available levers provide greater versatility. Mo-

mentary action.

LSB: With 100° minimum overtravel.

Various levers that fit side rotary shafts

may be used on the top rotary shaft.

Switch is ideal when increased overtravel

is required. Momentary action. Standard

operating temperature range from -1°C

to 121°C [30°F to 250°F].*

TOP PLUNGERS: Available with 4,83 mm [0.19 in] minimum

overtravel. Top pin plungers are offered in pin plunger, an

adjustable plunger, and a roller plunger. Standard temperature

range of -12°C to 93°C [10°F to 200°F].

LSC - Top pin plunger: A corrosion-

resistant steel plunger for in-line actuat-

ing motion. A boot seal on the plunger

and a seal between the actuator head

and housing keep out coolant, dust, and

chips. Momentary action.

LSD - Top roller plunger: A corrosion-

resistant steel roller and plunger that is

adjustable to 90° angles to accept cam

or slide operation from any of two direc-

tions. Boot seal on the plunger and a seal

between the actuator head and housing.

Momentary action

LSV - Adjustable top pin plunger:

Provides easy application and saves on

installation time. The operating points

of the switch can be adjusted from 52,8

mm to 59,3 mm [2.085 in to 2.335 in].

Seals are the same as the pin plunger.

Momentary action.

*(Fluorocarbon seals are preferred for temperatures above 93°C [200°F]).
