Tiefenbach Magnet Switches


Tiefenbach – Extra Heavy Duty Magnet Switches, for Industrial, Mining & Off-shore industries, available in Weatherproof or Intrinsic Safe applications, in Monostable or Bistable.


Magnetic switch monostable:
Type: proof
iK177L11… for intrinsically safe equipment

Magnetic switch bistable:
Type: proof
iK177L21… for intrinsically safe equipment

  • Contact less activation by permanent magnets
  • Maintenance-free
  • High switching capacity
  • Large temperature range
  • Any installation position
  • High responsiveness up to max. 30 m/s
  • Long service life – 10 to the 9 switching cycles
  • Almost instantaneous
  • With connection cable 2 m, 5 m, 10 m or 20 m


The switches are employed as magnet-sensitive contact less bistable limit switches.

Design and mode of operation:
The magnetic switch consists of two dry-reed contacts embedded in cast resin and mounted in a corrosion-resistant brass casing. By the motion of a magnet, the contact and thus the circuit can be made or broken. When the contact is made, the magnetic field increases by the squared power as the air gap between the contact studs decreases and the contact closes abruptly. The contact switches almost instantaneously owing to the very small distance between the contact studs and to their low mass.

Bistable switches wK177L21….
The contact is magnetically locked in its respective position by means of two magnetic clamps. As the switching magnet is more powerful, the switch is set when the magnet moves over and is set back when the magnet returns.

Monostable switches wK177L11….
With this switch design, the switch remains activated for as long as it is influenced by the magnetic field. The switch returns to neutral position when the magnet is removed.

Permanent & Electro-Magnetic Actuators:

Encased in Red Brass – North OR South pole.

Hyde Park CT1000 Series

Ultrasonic Counting Sensors SUPERPROX®

CT1000 Series Counting Sensors. These are able to count separated, staggered, back-to-back, irregular shaped, and “patterned” bottles with a high degree of accuracy. They operate in the harshest environments.

Now there’s accurate counting of containers over a wide range of sizes, even in the presence of “dither” or jiggling back and forth.

Accurate counting of containers on single-file conveying systems has challenged the container manufacturing, food processing and packaging, beer/beverage, and pharmaceutical industries for many years. The Model CT1000A series is an ultrasonic sensor designed especially for achieving accurate container counting.

The Model CT1000A ultrasonic counting sensor counts separated containers as well as those moving back-to-back at line speeds up to 2000 containers per minute. The accuracy is maintained in the presence of line stoppages, reversals, and container jiggling in front of the sensor. The sensor provides a setting for large versus small container sizes, and regular versus irregular container shapes.

The Model CT1000A sensor is capable of counting various size containers with a single setting of the sensor as long as the proper spacing between the rails and containers is maintained and the distance from the sensor to the containers is not changed.

This Feature eliminates the need to stop the conveyor line and readjust the sensor each time there is a change in the container size or material.

Made of tough ULTEM®, the sensor measures 139.7 mm (5.50″) long x 66.5 mm (2.62″) wide x 78.7 mm (3.10″) high. With protection ratings of IP67 and NEMA 4X (indoor use only), the sensor resists most acids and bases, including most food products. It is sealed to withstand dusty, noisy, non-condensing-humidity, high-pressure, wash-down environments typically associated with beverage-filling operations. The transducer face of the sensor is made of silicone rubber.

AECO-Capacitive Level

Capacitive level sensor for bulk products   SC and SCD series:

These are used where it is necessary to control with a high degree of security the level of non conductive substances both liquid and solid.

They are particularly used for controlling the level in silos for cereals and foodstuffs, in feed plants, foundries and cement works.

They function in the vicinity of the material to be controlled:

  • Supply voltage 24 Vac or 110/220 Vac
  • Relay output with 1 pole changeover from 5A to 220 Vac.
  • Led incorporated
  • Sensitivity adjustment
  • Selector of min/max level
  • SC series with power supply-amplifier incorporated within probe
  • SCD series with power supply-amplifier separated from probe
  • SX2 type with power supply-amplifier in plastic body
  • Bar electrodes of teflon in standard lengths of 300/500/800 mm
  • Plastified cable electrodes in standard lengths of 1/2/3/4
  • metres
  • Housing in aluminium alloy with threaded fitting 1.1/2 inch GAS
