Sensors, monitoring devices and an entire elevator system are featured this month.
New Controller Module Supports Remote Monitoring
Schmersal Böhnke + Partner has introduced its bp408 lift controller module. It is compact enough to be fitted in door frames, eliminating traditional control cabinets. A built-in safety switch fulfills the requirements of EN 81-20 and -50. Functions also include self driving and collective control, priority and guest calls, and functions for “freedom from barriers” in accordance with EN 81-70. Its “highly developed group algorithm” is adapted to relevant systems and allows it to control up to eight lifts. Paired with the WinMOS®300 software, the module can provide a range of additional functions, such as remote monitoring and maintenance, and emergency call management. It can also be utilized by CANopen lift components.
Sensors with Increased Range
Carlo Gavazzi Inc. has announced an expansion of its popular sensors. The new Extra Extended Range ICB Series Inductive Proximity Sensors provide sensing distances up to three times the sensing distances of standard inductive proximity sensors, up to 10, 20 and 40 mm, depending on model. Additionally, calibration after assembly is allowed, enabling greater temperature stability, reliability and repeatability. A microprocessor design simplifies OEM customization requests, such as special output types, switching frequencies and timing functions. The associated diagnostic LED can be viewed from any direction and provides status, setup, short-circuit and overload indication.
The sensors have an operating frequency up to 2,000 Hz and carry cULus and CE markings, rated for operation from -25°C to +70°C (-13° to +158°F). Connection options include either a 2-m PVC cable or M12 disconnect plug.
Inductive Proximity Sensors, Cordsets
Carlo Gavazzi has released two new product lines designed specifically for harsh environments. Its ICS Inductive Proximity Sensors accommodate both hot and cold temperature extremes with an operating range of ‑40°C to +80°C. The three-wire DC ICS series is available in M12, M18, and M30 316L stainless-steel housings, with single or double sensing distance, flush or non-flush mounting, and normally open or normally closed outputs with 200 mA positive-negative-positive or negative-positive-negative transistor output.
The company’s IP69K CONB Series Cordsets are ECOLAB certified with one of the highest temperature ratings in the market: ‑40°C to 105°C. The CONB Series cord sets are intended to complement IP69K-rated sensors, including inductive, photoelectric and capacitive sensors. They are available in lengths of 2 or 5 m, with a straight or 90° connector, and in non-illuminated or LED versions.
Safety Brake Monitoring
Mayr GmbH + Co. KG has introduced an intelligent brake control module ROBA®-brake-checker. This module is not only able to energize brakes, it can also monitor them without the use of sensors. The product can be integrated into existing systems and communicate with superordinate controls. It recognizes the switching condition of the actuator and the wear on the brake linings, and detects safety-critical conditions prior to their occurrence. Any changes in the braking torque can, thus, be instantly detected and countermeasures initiated.
The product is designed for an input voltage of 24 or 48 VDC and can control brakes with a coil nominal current of 10 or 5 A. It detects when the brake condition changes (i.e., whether the armature disk has been attracted or released) and emits the respective switching condition of the brake via a signal output. The switching condition of safety brakes can, therefore, be recorded in machines and systems even without the usual microswitches or proximity sensors. It is able to detect a possible wear reserve or line breakage, or, if applicable, unpermitted heating. Dimensions of 30 mm in height, 69 mm in width and 73.6 mm in length allow integration into most control cabinets.
Home Elevator
Terry Lifts has introduced the Lifestyle Home Elevator, touted as a compact, easy-to-operate and efficient alternative to the chairlift. The lift is ergonomically designed and comes in an array of colors and finishes. Installation typically takes a few days, and distributors are located in numerous countries, including the U.S. and Canada. Features include:
- Fire protection in line with BS 5900:2012
- Pressure-sensitive safety surfaces to stop the lift if it is obstructed from above or below
- Prevention of travel when door is open
- Backup battery power
- Adjustable cabin lighting
- Capacity of 250 kg
- CE marking
