MINIATURE HIGH VOLTAGE REED RELAY NOW RATED UP TO 150°C
distance sensors to existing silos is easily possible at any time.
COMPACT, HIGH PERFORMANCE SENSOR
The optoNCDT ILR2250-100 laser distance sensor measures distances up to 150m with an accuracy of < ± 1mm. The sensor measures accurately even on difficult surfaces such as dark, structured or weakly reflecting objects. Without any special adaptations to the target, the sensor has an impressive range up to 100m. Adding a reflector to the target extends the range to 150m. Protected by an IP65 die cast aluminium housing, the optoNCDT ILR2250-100 is suitable for a wide range of applications, from transport, logistics and conveyor systems, to automation, metal processing, production monitoring and unmanned drones or vehicles. It has already found uses in monitoring large coil diameters and gantry cranes. The combined long range and high accuracy of the sensor has also found particular benefits in the measurement and control of diameters for hot ring rolling.

In terms of its technical performance, the sensor is unsurpassed in its field, providing excellent repeatability (<300µm), resolution (0.1mm) and linearity (< ± 1mm), resulting in extremely stable measurements and excellent signal stability. The sensor’s small footprint (102 x 53 x 50mm) and weight (254g) represent a 65 per cent reduction in size and weight compared to its predecessor, allowing it to be easily installed in narrow or restricted spaces in production lines and machines.

ickering Electronics has launched a new high temperature high voltage single-in-line reed relay that can operate at up to 125°C. The new Series 104HT relay belongs to a family of miniature high voltage reed relays and is available in the SIL package on a 6.35mm (0.25in) pitch, with a stand-off voltage capability of up to 4kV. “High temperature can significantly affect the performance of reed relays, and many devices are only able to operate at up to 85°C. By designing these devices with increased magnetic drive and using specialist potting materials to sustain insulation resistance, Pickering can now offer reed relays that perform at elevated temperatures, and which can be stored at up to 150ºC,” says Kevin Mallett, technical specialist at Pickering Electronics. The Pickering Series 104 reed relays feature internal mu-metal screening, effectively countering any magnetic interference. As an added option, electrostatic shielding is also available. These versatile relays come in a range of configurations, including 1 Form A, 2 Form A & 1 Form B, and can be fitted with coils of either 5, 12 or 24V, with optional internal diode protection. With four types of dry switches to choose from, these relays are capable of standing off 1.5, 2, 3 or 4kV DC. For those requiring higher stand off voltages, the 3kV and 4kV versions have been designed with an increased clearance between the switch and coil pins to accommodate the higher voltage. If the user requires even higher voltage ratings, Pickering provides a variety of build options, or fully customized designs tailored to meet unique requirements. Mercury wetted devices are also available for applications where bounce free switching is required. These are rated at 1,500V DC minimum stand-off, 500V DC switching at up to 50W. For users requiring a reliable reed relay that can perform well in high temperature environments, the new Series 104 high temperature, high voltage reed relays are worth considering. They suit a variety of applications, including mixed signal semiconductor testers, high-end cable testers, backplane testers, medical electronics, electric vehicles, solar energy and high voltage instrumentation.
