The HDLS Series Heavy Duty Limit Switches offer a wide choice of mounting and actuator options. Housed in a rugged, die-cast zinc body which is epoxy coated for protection, they are perfectly suited to special applications in harsh duty environments where conventional limit switches may not be used. Versatile and full featured, they are designed for long life.
Listings referenced in this section are mainly standard. Low temperature and fluorocarbon (FC, high
temperature) construction is available in all forms of HDLS limit switches. For temperature ranges see
tables. Also available are factory sealed, pre-wired switches.
Low temperature switches have fluorosilicone diaphragm, shaft seals and external boot seal (where
applicable) plus a low temperature lubricant. If prewired with cable, temperature limits are -10 °C (14 °F)
flex and -30 °C (22 °F) no flex.
Completely fluorocarbon (FC) sealed, high temperature, chemical resistance switches have a full FC
body gasket covering the switch cavity. Rotary types have an extra FC seal on the operating shaft, while
plunger versions have FC boot seals. They are for use in applications where the environment includes
fire-resistant synthetic fluids. The additional FC seals also promote longer operating life for rotary
actuacted HDLS switches in applications where the temperatures are normally -12 °C to 121 °C (10 °F to
250 °F). If prewired with cable, temperature limits are 105 °C (221 °F) dry and 60 °C (140 °F) wet.
Honeywell's Limitless product line combines the best of Honeywell's global limit switches with the latest commercial state-of-the-art wireless technology. Wireless-enabled limit switches can be used for position sensing and presence/ absence detection for an endless number of applications. The Limitless Series is especially beneficial for remote monitoring applications where wiring or wire maintenance is not physically possible or economically feasible. Combining this greater flexibility with proven harsh-duty packaging can result in increased efficiencies for machines, equipment, OEMs, and operator
The 14CE/914CE Series offers a miniature, rugged, compact, pre-wired switch which has proved itself successful and gained wide market acceptance. The entire range of 14CE and 914CE switches has been approved to meet the requirements of the Low Voltage directive and is therefore CE marked. CE switches have different degrees of protection from IP66 to IP68 for the fully booted head styles. The cable entry is fully potted using a special compound to ensure that ingress is virtually impossible.
The BZE/DTE Series general purpose enclosed limit switches offer precision operation and sturdy actuation in a compact but rugged aluminium housing. The large wiring enclosure means that the user can get access to wire the device simply. The switch incorporates high repeatability of the switch point early in the travel of the switch. This is achieved through a very tolerant over-travel mechanism which ensures that application drift will not affect long term accuracy of the switch.
LS Series compact limit switches are carefully designed for accurate repeatability under the most stringent conditions. Compact size and field adjustable features greatly extend the flexibility of these switches. Heads may be positioned at 90° increments. Side rotary models can be adjusted for clockwise and/or counter-clockwise operation. Actuators can be set and locked in any position through 360°. The rugged housings and actuator heads are constructed from cast aluminium, capable of withstanding physical abuse. Protection against oil, water and dust is achieved by O-ring seals on the actuator shaft; a ring seal between head and body; and a seated compression seal between cover and case. The LS fits in many places too small for any other fully adjustable limit switch
