Proximity Cards (20 suppliers)
Proximity cards or tokens do not need to touch a reader in order to validate a transaction. Their radio-wave transmission technology is highly secure and their readers can be hidden behind walls, in clean, maintenance-free, vandal-proof locations. Best, because proximity readers don't require contact, they speed the flow of human and vehicular traffic through checkpoints. These cards and tokens can remain in pockets, purses, or even on the front seats of vehicles and still be read by the system. Each proximity card contains a coil of wire that acts as both the receiving and transmitting antenna and a small, integrated circuit that is programmed with a unique ID code. These cards are powered by the voltage generated from a reader's magnetic field in relation to the card's antenna coil. Once energized by a reader, the card transmits its ID information. Transmission is so fast that access verification takes place in less than a quarter second. There are two types of proximity cards or tokens such as active and passive proximity cards.

Proximity Sensors (66 suppliers)
Proximity sensors are sensors that detect the presence of near objects without any physical contact. The maximum distance this sensor detects is defined as 'nominal range'. Proximity sensors offer a variety of ways to sense the relative position of specific machine elements requiring continuous monitoring.
Proximity Sensors (117 suppliers)
Proximity Sensors is a device that sense when one object is close to other object. They indicate only the presence or absence of an object within their sensing region but some can give some information about the distance between the object and the sensor as well. They are used for detecting the properties of the surface of an object without touching it. It is used in collision detection situations and in detecting approach situations for the arm.

Proximity Switches (58 suppliers)
Proximity Switches are non contact type switches that are used to sense the presence or absence of an object without actually contacting the object. They combine high speed switching with small physical size.
Proximity Switches (78 suppliers)
Proximity switches are non contact-type switches that are used to sense the presence or absence of an object without actually contacting the object. Proximity switches combine high-speed switching with small physical size. In a proximity switch mode, a field amplitude threshold is set, below which a solid state switch changes the signal output from high to low or vice versa. In this manner, a digital signal is produced, which indicates whether a metal object has approached closer than a prescribed value.
