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.
